Beans

Winged BeansPsophocarpus tetragonolobus are grown principally for their edible “winged” pods.  Pick them when you can bend the pod without breaking it or it will become too tough to eat.  The leaves and flowers are also edible and quite appealing.  The plants thrive in the hot humid summers of southern Florida with few disease or insect problems, though nematodes can be a problem.  Most varieties of this jungle plant from Borneo only bloom and set fruit when the days become very short, so they are planted in early fall. The variety ‘chimbu’ produces longer pods than most and is a striking deep red color. For pods in a summer garden in Florida or “up north,” be sure to purchase a “day neutral” or “long day” variety.  Seed available at ECHO Nursery

“For pods in a summer garden in Florida or “up north,” be sure to purchase a “day neutral” or “long day” variety [of winged bean]. ”

Adzuki Bean, Vigna angularis (a.k.a. azuki bean) and Southern Pea (a.k.a. black-eyed pea, cowpea, crowder pea) Vigna unguiculata subsp. unguiculata.  In southern Florida during the summer months Phaseolus (green beans or common beans) do not grow well due to the heat, moisture and diseases.  However, the Vigna beans usually thrive.  Here we feature two types, with a third in the following entry, all of which will do well in the summer Florida garden.  There are similarities, but differences in their uses as well.  Southern pea and adzuki have the same bushy growth habits, although the adzuki bean itself is a bit smaller than the pea.  Whereas southern pea is prepared more as a shell pea, the adzuki is prepared more as a dried bean or pulse.  At ECHO we have also noticed that adzuki bean is consistently more insect tolerant than the southern peas.

Yardlong BeanVigna unguiculata

Yardlong BeanVigna unguiculata subsp. sesquipedalis, (a.k.a. asparagus bean) produces pods similar to climbing green beans of temperate regions except that they really can be up to a yard long.  The yard-long bean is eaten as one would eat fresh or green “string” beans, either cooked or uncooked.  There is a purple “yard long” bean that is visually quite striking in the garden.  The yard-long bean is an annual propagated by seed.  Seed available at ECHO Nursery

Tubers & Corms

Cassava (a.k.a. Tapioca, yucca, manioc), Manihot esculenta, is an important root crop that is grown as a staple food in many parts of the tropical and subtropical world.  Tapioca is made from processed cassava tubers.  Cassava is tolerant of drought and poor soil, but needs good drainage. It is a perennial shrub harvested for its roots about 8-12 months after planting. Our cultivated varieties grow to about 8 ft. and tend to sprawl. The young, fully expanded leaves can be eaten after boiling.  They contain 11-39% protein on a dry weight basis. Cassava is propagated by stem cuttings

Both the leaves and roots contain a cyanide compound, so both should be cooked and the water drained. Cassava should only be eaten in moderation. This reduces cyanide to a very low level.  Check the web or ask a friend from the tropics for more details. Only eat cassava that is known to have more moderate amounts of cyanide. Cassava is frost sensitive but can re-sprout from the underground part of the stem if a freeze kills it to the ground.  Keep in mind that your liver can detoxify modest amounts of cyanide and has almost certainly done that for you.  Compounds that turn into cyanide when exposed to acid or chewed by an insect are one of the common ways nature has of helping plants survive.    Plant available at ECHO Nursery

JicamaPachyrhizus erosus

JicamaPachyrhizus erosus, a.k.a. yam bean is a bean plant, the seeds of which must not be eaten.  It is grown for its edible underground tuber.  The tubers begin to form when days are short around December and are harvested in January or February, though they need to be planted in the summer to take advantage of the rains and long days to develop the massive vines which pour energy into forming the tubers.  Tubers will be the size of a grapefruit or larger if planted in May or June and the size of an apple if planted in August. You will find jicama in most grocery stores.  The shredded, raw, white crunchy item that you see on fancier salad bars is jicama.  It remains crunchy when cooked in a stir fry or soup, so can be used as an inexpensive substitute for water chestnut.  Jícama is an annual propagated by seed. Jicama seeds are available in the ECHO Bookstore.

 

Taro, Dasheen, Colocasia esculenta

Taro, Dasheen, Colocasia esculenta (a.k.a. eddo, cocoyam) and Tanier, Xanthosoma spp. (a.k.a. tannia, yautia, malanga) are two types of root crops that will grow well in the summer.  Taro and dasheen are grown principally for their large, edible starchy corms (underground root and stem structure).  Taro is grown in wet, paddy-like surroundings, is fibrous and has a spongy texture.  It is usually beaten to extract the starch which is made into poi.  Dasheen is grown in a drier, upland environment and the corms are crisp, easily cut and are eaten as a boiled or fried vegetable.  Colocasia has peltate (petiole attached to the leaf inside the leaf margins) shaped leaves to distinguish it from the Xanthosoma leaves which are sagittate (arrow head) shaped.

Xanthosoma species are also grown principally for their starchy corms, but many also have leaves that when cooked make excellent greens.  It is recommended to use the leaves that are freshly unrolling, although different species and different cultures will treat this differently.  Often the petioles are peeled and cut into sections revealing their spongy insides for use in soups.  These crops have varying quantities of oxalates and oxalic acid, and so it is recommended to boil them and discard the water to remove the acrid taste that may cause the sensation of pins and needles on your tongue.

You can find the corms of these crops in the grocery store and this will be your best source of propagation stock.  They can be cut and allowed to heal over or dry before planting them.  Make sure each piece has at least 1 bud or eye to sprout.

Sweet PotatoIpomoea batatas

Sweet PotatoIpomoea batatas, of most varieties will grow well in the summer and beyond in SW Florida.  ECHO has several varieties. They need very warm growing conditions so should be planted during spring and summer and harvested four to five months after planting. Propagation is by cuttings stuck directly in the ground or by small fleshy root pieces. These can be planted almost any time of the year, provided there is sufficient soil moisture.

Vine tips are high in protein; they may be cooked and eaten. The fleshy roots are a good energy food, and the roots with orange-colored flesh indicate high quantities of vitamin A.

Water ChestnutEleocharis dulcis, (a.k.a. Chinese water chestnut) is a popular ingredient of Chinese cooking that can be easily grown in an inexpensive plastic wading pool. The best planting time in south Florida is March through June. Start plants by placing corms in a large styrofoam coffee cup with soil and some standing water. After a good root mass has developed, place 6-10 plants on the bottom of the pool, stuff pine needles tightly around them and periodically add some fertilizer. Keep flooded with water. When the tops die down in November, you should find dozens of “chestnuts” on the bottom. You can also just grow in regular soil, but then the corms will be more difficult to harvest because they will likely be spread throughout the soil. Corms can be stored in moist mud or refrigerated at 50 to 55º F. They should not be allowed to dry out.

You can find chestnut corms in fresh markets where Asian vegetables are sold.

YamDioscorea alata

YamDioscorea alata, (a.k.a. greater yam) is often confused with sweet potato, which is sometimes called ‘yam’ in the United States. Those who know the tropical yam, however, will not mistake it with sweet potato. Yam is a tuber crop that is well known throughout the humid tropics of Tropical America, the Caribbean, Africa, and Asia. In Florida you will see it sold in the supermarkets under the Spanish name, ‘ñame’ (pronounced: nyah-may).

The yam is an important carbohydrate food that is relatively easy to grow. Yams have a very specific life cycle. Unlike the sweet potato, which can be planted by vine cuttings almost year-round, the yam is planted once-a-year, when the stored tuber begins sprouting. At ECHO, this usually begins in February or March. As the tuber breaks dormancy, the energy is transferred from the tuber into stem and leaf growth. This vegetative stage, lasting 6 to 8 months, occurs during the warm and humid summer months. A new root system with multiple tubers develops with most of the tuber development occurring toward the end of the rainy season and into fall. When the vine dies back, the tubers are ready for harvest. At ECHO this usually occurs in late November.

Yams do well in sun or partial shade and prosper with ample rainfall. They require good drainage, and therefore, are often planted on mounds or ridges. They are most commonly staked but can be planted on a trellis or at the base of a sufficiently strong tree. At ECHO it has worked well to stake them with bamboo, not more than 1 inch in diameter as the vines have some difficulty twining up the large bamboo’s slick exterior. Growth is lush and very vigorous once the rains begin. Remember the vines die back in the fall. They then get a number of leaf diseases and look sickly; however, this has little effect on the tuber.

When harvesting, be careful as the tuber skin is thin and easily damaged. The tubers are often large, several lbs. a piece, often as great as 15 lbs. or more. The yam is consumed much like a potato – peeled, then boiled or baked. Peel or cut away any discolored areas. Yams reportedly make good French fries and chips. The storage life of the yam tuber is short, averaging maybe 2 to 3 months, due to the high moisture content. One recommendation is to harvest them as needed when they are in the dormant stage. If unused, the tuber will begin to sprout in the spring.

For propagating, yam sprouts first at the top, which is the most desirable planting piece next to a whole ‘seed’ tuber. Cut off a section about the size of an adult’s fist and cure it a few days in the shade before planting. Yam is a wonderful food and is generally an easy, dependable crop to grow.

Note: Planting should be done in February or March to allow for the greatest amount of sunlight and heat units for growth and tuber development.  Yam is then harvested in November to January.  You may purchase yams in the supermarket (generally found under the Spanish name, ‘ñame’) and these may be sprouted and planted in your garden.

Word of Caution:  A wild form of Dioscorea alata called “winged yam” is a noxious, class I invasive weed species in Southern Florida.  It is not the same as D. bulbifera the “air potato,” also a class I invasive, but care must be taken when planting this crop.

Fruiting Vegetables

OkraAbelmoschus esculentus (a.k.a. gumbo), and EggplantSolanum melongena, well-known vegetables to most Americans, will grow well planted spring or summer in SW Florida.  Both can be harmed by root knot nematodes.  The pods of two okra varieties, ‘Borneo’ and ‘African’, can be eaten at a much larger size than most standard okra varieties. These two varieties both out-produce most other okra varieties in the late summer planting at ECHO while other varieties do better in earlier plantings

Eggplants come in many colors, shapes and sizes, from large, melon-sized to those that are egg-sized to those that are pea-sized.  Their cheerful color variations make an appetizing addition to a fresh vegetable platter, soups, stir-fries, casseroles and other dishes.

Both okra and eggplant are propagated by seed.  Seed available at ECHO Nursery

Ethiopian KaleBrassica carinata

Ethiopian KaleBrassica carinata (a.k.a. Abyssinian cabbage) is an annual cole crop which originates in the East African Plateau. It tolerates high temperatures and high humidity, setting seed where other kale varieties will not.  Young tender leaves and stem tips of Ethiopian kale may be eaten fresh in salads or cooked. Older leaves and stems may be cooked and eaten like collards. Flower stalks may be cooked and eaten like broccoli. It can also be used as a fodder crop species for animals.  Ethiopian kale is reproduced by seed and it is easy to designate an area in the garden for constant production of this prolific, nutritious leafy vegetable. Seed available at ECHO Nursery

Cherry TomatoesLycopersicon esculentum

Cherry TomatoesLycopersicon esculentum var. cerasiforme, can produce during summer months, however, only varieties that are resistant to nematodes should be tried at any time.  The package or at least a catalog description should indicate which diseases the variety is resistant to by using letters (V=verticilium wilt; N=nematode; F=Fusarium wilt; T=tobacco mosaic virus, among others).  Even tomato vines that do well may not set fruit because of pollination problems during the warm season. Daytime temperatures must be under 90 F and nighttime temperatures under 70 to set fruit.  Other than cherry tomatoes, romas, grape and salad tomatoes will also produce during the summer months.  Tomatoes are propagated mainly by seed, but some have successfully propagated them by cuttings.  Seed available at ECHO Nursery

Hot peppers, Capsicum annuum

Hot peppers, Capsicum annuum, C. frutescens, C. chinense, and C. pubescens, can be grown as annuals, but they are actually perennials, and in countries where it does not freeze they can grow for several years.  The variety ‘Indian firecracker’ is particularly striking when used in a container garden. The small red and green peppers make the plant look like it is decorated for Christmas.  The larger “sweet peppers” are annuals and usually do not do well in the summer.  Plant and seed available at ECHO Nursery

Bunching onionsAllium fistulosum

Bunching onionsAllium fistulosum, (a.k.a. Welsh onions) keep dividing, forming bunches that can be cut and used like green salad onions.  These perennials may be propagated by divisions or by seed.

 

Garlic ChivesAllium tuberosum

 

Garlic ChivesAllium tuberosum (a.k.a. Chinese chives) make a great grass-like border or container plant, thriving through all seasons here in Florida. They are a great addition to an herb garden or as a border. Growing best in moist soils, they are also drought resistant.  They grow well in sun or partial shade. The white stems and green leaves are used like green onions or chives to add flavor to salads, sour cream, stir fries, omelets and soups. They also make delicious herb butter and are popular in Asian cooking. They are perennial and should live for years, with clumps growing larger each year. Garlic Chives do not form a bulb.  Most varieties have a bad reputation of producing a lot of seeds that can spread into the lawn.  But ECHO was given a start of a variety being grown by a Japanese lady in the local rare fruit club.  It almost never blooms in southwest Florida and hence does not become weedy.   Harvest by cutting off at ground level. DO NOT DIG UP THE ROOTS WHEN YOU HARVEST!  If you leave the roots they become very dense and the edible part will grow back in 3-4 weeks.  Garlic chives are perennial and are propagated by seed or division.  Plants propagated by seed will themselves produce seed and may become weedy.

“Garlic Chives make a great grass-like border or container plant, thriving through all seasons here in Florida. ”

If you want color, a plant with similar looking leaves called society garlic produces attractive purple flowers (and seeds).  It also has a garlicy taste, but not nearly as subtle a taste as garlic chives. Plant available at ECHO Nursery

Wax gourdBenincasa hispida

Wax gourdBenincasa hispida, will grow best in the hot but dry late spring, but might produce into the summer months.  It is sometimes called “Chinese winter melon,” and is popular in Asian markets and cuisine.  The white flesh of the melon-like fruit is cooked in soups.  The fruit is covered with an attractive white waxy “bloom” that protects it from microbial and insect attack and from drying out.  Consequently, it stores exceptionally well.  As with other plants in the cucurbit or cucumber family, the young shoots and flowers of the wax gourd may also be eaten in soups, in stir-fries or cooked and eaten as greens.

Tropical pumpkinsCucurbita moschata

Tropical pumpkinsCucurbita moschata, are one of the same species of squash grown in temperate climates although these have been selected for production in the tropics.  Latin markets will likely have ‘Calabaza,’ which is the same species.  They can be very productive any time except during the coldest weather. Tropical pumpkins can be used the same as the temperate pumpkin, but it can also be baked just like a winter squash or cooked when it is small and green and used like a summer squash.  Additionally, the flowers and young shoots may be cooked and eaten as greens or stir-fry.

The pumpkin leaves can be damaged severely and quickly by a small caterpillar.  See “vegetable amaranth” for a discussion of how to control it.  The vigorous vines will grow along the ground and send out new roots, so planting near an area where it can sprawl is ideal.  A few months later you might find the vine dead where you planted it but the new portion thriving many feet away. This may help the roots avoid nematodes. Seed available at ECHO Nursery

Edible Leaves and Shoots

Basket VineTrichostigma octandrum, a.k.a. Haitian basket vine, hoop vine, liann panye (in Haiti) grows as a large perennial, sprawling bush. It is considered a native species in South Florida and on many of the Caribbean islands.  It has long pliable stems that are used in making baskets. The young leaves, eaten after cooking, are an outstanding green vegetable. They are reported to be extremely nutritious. Discard the cooking water. Some boil the leaves a second time in fresh water to remove traces of bitterness.  (Note that the opposite of sour is bitter, so some vinegar or vinegar-based salad dressing might make it a better match for the taste buds of some.) There have been a few times where it has been killed to the ground in a freeze at ECHO, but will grow back.  Although basket vine has a beautiful purple flower, it is propagated principally by cuttings.

“There have been a few times where it [basket vine] has been killed to the ground in a freeze at ECHO, but will grow back. ”

Cassava ,  Manihot esculenta

CassavaManihot esculenta

Cassava (a.k.a. Tapioca, yucca, manioc), Manihot esculenta, is an important root crop that is grown as a staple food in many parts of the tropical and subtropical world.  Tapioca is made from processed cassava tubers.  Cassava is tolerant of drought and poor soil, but needs good drainage. It is a perennial shrub harvested for its roots about 8-12 months after planting. Our cultivated varieties grow to about 8 ft. and tend to sprawl. The young, fully expanded leaves can be eaten after boiling.  They contain 11-39% protein on a dry weight basis. Cassava is propagated by stem cuttings

Both the leaves and roots contain a cyanide compound, so both should be cooked and the water drained. Cassava should only be eaten in moderation. This reduces cyanide to a very low level.  Check the web or ask a friend from the tropics for more details. Only eat cassava that is known to have more moderate amounts of cyanide. Cassava is frost sensitive but can re-sprout from the underground part of the stem if a freeze kills it to the ground.  Keep in mind that your liver can detoxify modest amounts of cyanide and has almost certainly done that for you.  Compounds that turn into cyanide when exposed to acid or chewed by an insect are one of the common ways nature has of helping plants survive.    Plant available at ECHO Nursery

ChayaCnidoscolus aconitifolius

ChayaCnidoscolus aconitifolius, is sometimes called “tree spinach.” Its large leaves are boiled and eaten, especially in Mexico. It is also used to wrap tamales. The plant becomes a shrub about the height of a person and is quite attractive. Occasional pruning will make a more compact, bushy plant.  Only if left unattended for a few years will it even resemble a tree here in Florida. The stems break so easily that you can easily prune them

As with its cousin, cassava, the leaves of chaya must be cooked around 10 minutes or more in boiling water or cooked as a stir fry or baked in a casserole to remove the small amount of cyanide they contain. Do not use them fresh in salads.  The texture of the chaya leaf is firmer than many cooked greens.  They remind me of collard greens.  Most varieties of chaya have small stinging hairs that are harmless after cooking, but the variety ECHO sells is free of these hairs. A USDA study in Puerto Rico reported that one can get higher yields of greens per unit area with chaya than any other vegetable they have studied.

Chaya is unique in that it is exceptionally resistant to the hot humid weather of a Florida summer and to extreme dry weather (that is the climate in Central America where the plant is native).  Insects have not bothered chaya at ECHO.  If the plant blows over in a tropical storm or the above-ground part is killed by a freeze, don’t worry. This often makes for a prettier, more unique plant, as the main stem sends up additional branches and a bushier plant results.  Chaya plants almost never produce seeds, but propagate easily by cuttings. Plant available at ECHO Nursery

KatukSauropus androgynus, (a.k.a. sweet leaf) is one of the staple vegetables in the rainforest climate of Borneo. It has become one of the favorite salad greens of the staff at ECHO, and is eaten either cooked or fresh for its nutritious leaves and shoots. The unique flavor of these leaves is most similar to raw peas when eaten raw. It grows exceptionally well in Florida, going dormant in the winter.

Katuk is disease and pest resistant, tolerates most soils, and grows in sun or shade. For the best tender shoots and leaves, grow katuk in at least half shade and fertilize frequently. This shrub should be occasionally pruned to 3-5 feet since it tends to grow straight up until it falls over. In SW Florida it can be killed back by hard freeze but grows back from the ground and may re-grow bushier than before.  In Asia, katuk is propagated by seed as well as cuttings, but in SW Florida we have not been very successful with seed propagation.  Plant available at ECHO Nursery

 

KatukSauropus androgynus

MoringaMoringa oleifera

MoringaMoringa oleifera, (a.k.a. horseradish tree) is a tree grown for food and seed at ECHO.  It is one of the most requested seeds in ECHO’s seed bank. This is due to its many edible parts and its ability to survive in arid parts of the world. It is an exceptionally nutritious leafy vegetable. The large frilly leaves can be broken off easily at the stem and carried inside. The tiny leaflets can then be quickly pulled off between the fingers. Tender growing tips can be cooked stem and all. At ECHO, leaves are boiled as any green or added to soups or rice. In the southern portions of the United States the tree will probably survive a hard freeze but may be killed to the ground. Even where no freeze damage occurs, some people cut it back to about 4 feet each year.  This causes the leaves to be closer to the ground for ease of harvesting. If not forced to branch by pruning, the tree becomes tall, spindly and in most cases not very attractive. We do not recommend it as a prominent shade tree or landscape specimen.

Moringa might have potential as an annual vegetable farther north.  We are told that as far north as Gainesville Florida it is grown as a “cut and come again” perennial.  We were sent a photo of a tree that was started in a greenhouse, transplanted out, and grew to the height of eight feet in Wisconsin before winter killed it. Aside from eating the leaves, very young pods can be cooked and eaten like asparagus or green beans. Pod production is variable and seems to be increased by stress. Some trees bloom at less than a year old and others take longer.

Along with the moringa leaves and pods, the blossoms are also edible.  All parts have a taste similar to mild horseradish. When trees are about 3‑4 feet tall, they can be pulled out of the ground and the roots grated and used like horseradish. The root bark is toxic and should be peeled off before grating. Eat the roots in moderation only.  Personally I just buy horseradish if that is the flavor I want and don’t risk the potentially harmful chemicals in the roots.  Crushed raw leaves may irritate the skin and, if eaten in quantity, can be purgative. Under good conditions the tree can easily reach 15 feet the first year. The wood is very soft and does not make good fuel wood.  Moringa may be propagated either by seed (available in ECHO’s bookstore) or cuttings. Trees from cuttings tend to be more susceptible to blowing over in the wind because the roots tend to be more shallow.   Plant and seed available at ECHO Nursery

Amaranth (vegetable type), Amaranthus tricolor

Amaranth (vegetable type), Amaranthus tricolor (a.k.a. tampala) is attractive (especially the variety ‘tiger leaf’) and produces leaves that taste much like spinach when cooked.  Though it will grow well in the summer, stay alert to the likely arrival of small caterpillars that can devastate it within a few days.  The natural insecticide called B.t.® or Dipel ® can be bought at your garden center and will control the insect if used in time.  Vegetable amaranth or tampala is an annual and is propagated by seed.  Seed available at ECHO Nursery

Lagos spinachCelosia argentea

Lagos spinachCelosia argentea (a.k.a. quail grass), is a cousin to vegetable amaranth but much less prone to insect damage.  It is quite popular in SE Asia as well as West Africa where it originates (presumably named for Lagos, Nigeria).  As a young plant before it flowers, it makes a tasty cooked green.  Harvest it when it reaches 8-12 inches in height (before it flowers), cut up the whole plant except for the roots and put it into the pot.  Boil it for at least a minute or two and discard the dark water.  It is very much like cooked spinach in taste, color and texture.

We found out the hard way not to steam cook it because boiling in water is needed to remove oxalates that otherwise leave a burning sensation on the tongue.  It also has a beautiful flower later in the year; though at that stage the leaves become narrow and are not useful in cooking.  Lagos spinach is an annual and is propagated by seed.  There is a red- and a green-leafed variety.    Seed available at ECHO Nursery

Cranberry HibiscusHibiscus acetosella,

Cranberry HibiscusHibiscus acetosella, a.k.a. false roselle or red-leaf hibiscus has striking red leaves and is similar to Japanese maple, in both leaf shape and color. It can be planted in the spring and kept pruned for an attractive annual shrub and may be grown as a temporary hedge. Cranberry hibiscus is nematode and insect resistant and does well in sandy soil.

The young tender red leaves have a tart flavor and are an attractive addition to fruit and tossed salads, slaws, or stir fries. In the fall it has pink blossoms. About thirty blossoms can be picked at dusk after they have folded, and blended with lime juice and sugar to make a beautiful and tasty drink. The petals add a bright red color rather than any special flavor.  Pinch the tips of stems as it grows to make it bushy, otherwise it will grow several feet tall and fall over.  Cranberry hibiscus may act as a long-term annual or as a short-term perennial and can be propagated by seed or by cuttings.  Plant and seed available at ECHO Nursery 

“The young tender red leaves [of cranberry hibiscus] have a tart flavor and are an attractive addition to fruit and tossed salads, slaws, or stir fries.”

RoselleHibiscus sabdariffa i

RoselleHibiscus sabdariffa is sometimes called “Florida cranberry” because of the bright red, crunchy, sour calyx that can be used somewhat similarly to cranberries in recipes.  The calyx surrounds the developing fruit and seed and is the size of a small nut.  A very popular drink is made from the calyx in many tropical countries by cooking them in water, then adding sugar and lemon juice and cooling.  Plant roselle later in the summer to avoid likely root knot nematode damage.  It will not bloom and form the edible part until around October. Roselle, an annual is propagated by seed.    Plant and seed available at ECHO Nursery

Okinawa SpinachGynura crepioides

Okinawa SpinachGynura crepioides forms a dense, non-vining, edible ground cover, or as a specimen plant that grows well in full sun or partial shade. Grown commercially in China, the plant is a vigorous, perennial vegetable that is adaptable to a variety of tropical climates and requires little if any additional input. Okinawa spinach has attractive pointed leaves that are green on the top side and purple underneath. Young leaves and shoots can be eaten raw or cooked. Its rather insignificant yellow blossoms attract a constant stream of butterflies.  Okinawa spinach has potential to grow for more than one year but usually declines after about a year at ECHO.  It is propagated by cuttings.  Plant available at ECHO Nursery

 

Edible hibiscusAbelmoschus manihot

Edible hibiscusAbelmoschus manihot, is a shrubby perennial from Indonesia, the leaves of which are flavorful eaten fresh as one would eat lettuce or cooked either alone or added to soups.  It is grown exclusively for its leaves and is a very prolific producer, out yielding most crops planted for the production of leafy greens.  It is touted as having very high nutritive value.  Edible hibiscus must be propagated by cuttings, and is susceptible to nematodes.  If you do not have nematode-free soil, try planting edible hibiscus in containers.  The leaves can be as large as a slice of bread and one leaf can be used instead of lettuce.  The plant is a hibiscus but only blooms, sparingly, in SW Florida around January.  Plant available at ECHO Nursery

Tropical lettuceLactuca indica

Tropical lettuceLactuca indica, (a.k.a. Indian lettuce) grows well in full sun and tolerates the heat of the South Florida summer, growing to perhaps four feet tall.  When eaten fresh, the leaves are somewhat bitter.  Tropical lettuce has a nice flavor when stir-fried or boiled.  Tropical lettuce can be propagated by cuttings and by seed.  As this “tropical lettuce” is perennial, it can be cut back and it will re-sprout.  When you do this, remember to fertilize it to give it the needed boost.

 

Malabar spinachBasella alba

Malabar spinachBasella alba, a.k.a. Basella or Ceylon spinach is grown for its attractive edible leaves that are cooked.  Some people like the mucilaginous leaves and some do not.  It has potential to be a great substitute for lettuce in our hot summers.  The plant can grow up a fence or trellis or sprawl along the ground and, on top of mulch, forms an attractive ground cover. Malabar spinach is a perennial that comes in two stem colors.  The variety ‘Bangladesh’ has red stems; the variety “green” is entirely green. Both are propagated by seed and by cuttings.  Plant and seed available at ECHO Nursery

 

New Zealand spinachTetragonia tetragonioides

New Zealand spinachTetragonia tetragonioides is an annual green that often behaves more like a perennial. This is partially because the plant continues to grow and produce until the surrounding environment is no longer favorable for its growth and partially because it produces seeds close to the crown of the plant where they inconspicuously drop into the soil.  They then lie dormant until conditions are ideal for them to germinate and continue growing the following season.

Soak the seeds overnight before sowing.  Plant in pots or direct seed into the garden, spaced at 1-2 feet apart.  New Zealand spinach likes fertile soil, so the addition of organic matter in the form of compost, worm castings or animal manures will help maintain its lush vegetative growth.  Harvest by snipping 3-4 inch tips of the stems or individual leaves.  Picking them at least once a week ensures continued lush growth and leaf production.  They may be prepared as you would spinach – either by cooking (steamed, boiled, stir-fried) or by eating fresh in salads, and may substitute for spinach in any recipe. Plant and seed available at ECHO Nursery

How to Make your Own Worm Compost Bin

by Gabby Brown

Hey, this is Gabby, a volunteer at ECHO! I’m here to share with you an awesome post from the Childhood 101 blog about how to make a worm farm —at home, with your family! ECHO loves to promote composting with worms because they are great at turning food scraps, shredded office paper, and coffee grounds into incredible compost. We use worms on the ECHO Farm all the time, and we just taught a local school how to make their own worm farms! Here’s Childhood 101’s tutorial:

Have you or your children ever wondered what earthworms actually do for our earth? It’s hard to believe these smooth, and slippery little beings are actually one of the most significant contributors to our ecosystem; they are helpful to the natural soil system, as well as humans!

The scientists at Science Learning Hub, often describe Earthworms as engineers of a sort, because they change the physical, biological, and chemical properties of the soil. These changes influence the habitat and activities of other plants and organisms within that ecosystem. So—what you ask, are the actual benefits to starting your own worm farm?

Earthworms, fungi, and other bacteria decompose organic material found in compost piles, pastures, and plant waste. This decomposition leads to the absorption and incorporation of organic materials into the soil, and unlocks the nutrients hidden inside the organisms and plant matter.

Nutrients like phosphorus and nitrogen become readily available to the plants after the earthworms digest the matter. These nutrients are then excreted through the earthworm casts.

Other than creating the nutrients in the soil, the earthworms are also responsible for spreading it, and bringing it into closer contact with the plant roots.

Small spaces in the soil known as pores, are created by earthworms to increase water infiltration and circulate air. The worms create these small spaces by burrowing into the soil, this can lead to an increase in water infiltration by rates of 10% but also enhances root penetration, so the plants in the soil grow strong from the inside out!

Still curious on how to build your own? Follow these easy steps!

Materials:

  • 2 Large Styrofoam boxes, with lids.
  • Knitting needle/Chopstick/Screwdriver (to poke holes in your styrofoam box)
  • Worm Bedding: Compost, shredded paper, leaves, or straw works fine.
  • 1 Handful-Compost worms: You can buy them online or get them from a friend or neighbor that has a worm farm.
  • A newspaper

Directions:

  • Poke holes in the bottom of one of your boxes. This box is the ‘feeder box’ – where the worms will live and feed.
  • Fill half of the feeder box with the worm bedding. Make sure your bedding is moist but not wet. If you are using dry materials like straw or shredded paper, wet them first and then squeeze out any excess water.
  • Carefully scatter the worms on top of the worm bedding.
  • Soak the newspaper in water and lay it on top of the worm bedding. This will help keep the worms’ home dark and moist.
  • Place the feeder box on top of the other styrofoam box that doesn’t have any holes. This lower box is where the worms’ urine will be drained.
  • Place your worm farm in a shady spot in Summer and a sunny spot in Winter.

How to Care for Your Worm Farm:

  • Leave your worms to settle in for a week.
  • After a week, you can start adding kitchen scraps on top of the bedding, underneath the newspaper. Add only small amounts (around a handful) initially. As more worms breed they will eat more food. Eventually your worm farm should be able to handle most of your kitchen scraps.
  • Keep the top layer of newspaper damp and replace as needed.
  • To harvest the worm castings, move all the castings to one side and add fresh bedding to the empty side. Most of the worms will move to the fresh bedding and in a few days, you can then remove the castings. Worm castings are a great plant food. Grow seedlings direct in the castings or use it to top fertilize your potted plants or garden.
  • The worm urine, collected in the bottom box, is a super plant fertilizer! Pour the worm urine from the bottom box into a watering can, or bucket, and dilute 1 part worm juice to 20 parts water. It is too strong to use undiluted!
  • You can eventually increase the size of your worm farm by adding an additional feeder box on top, creating a multi-story worm farm. The worms will migrate up through the holes to the new bedding.
  • After the worms have all migrated to the top box you can plant seedlings directly into the initial feeder box to create a miniature garden.

Raising Hogs on Banana Silage in Myanmar

Farmers use what they have to make what they need for their family’s nutrition.

By Patrick Trail

Small home gardens are common to nearly all households in Myanmar’s Karen communities, and may be second only in occurrence to the pig that can be found being raised underneath so many homes. Like many other countries in Southeast Asia, land in Myanmar is as hard to come by as the protein that needs to be produced on it, making hog production a viable and popular source of animal protein. It would only take a few minutes for a visitor to realize the importance of agriculture to the Karen people.

Being omnivores and efficient consumers of household waste, pigs are well suited for integration into small farm systems where space and resources are limiting factors. Even one or two pigs can become costly to feed and will require, in many cases, expensive purchases of commercial feed.

“We seek to provide appropriate options for using on-farm resources, encouraging farmers to use what they have, to make what they need.”

For this reason, ECHO seeks to provide appropriate options for using on-farm resources, encouraging farmers to use what they have to make what they need. At our most recent Myanmar Seed Saving Workshop, our team met an attendee who had participated in our first Myanmar training event in 2013, where he learned to make fermented banana stalk silage for hog feed. We were delighted to learn that for the last four years he’s been promoting its use!

Now a Program Manager for World Vision Myanmar, our friend is working to spread this technology to communities within his reach.

One of his ongoing projects, which began with four participants, encourages the production of fermented banana stalk silage to supplement any purchased feeds needed for raising hogs. Through trial and error (and the creation of their own appropriate silage chopper), he and his coworkers have found that they can reduce the need for purchased feeds by up to 75% by supplementing with their own farm-generated feeds, thus improving production margins tremendously. The program now has 120 participants and is expanding to additional communities!

DIY Mango Jam: a step-by-step guide to the best homemade mango jam

By: Maddie Christy

Have you ever wondered how to make homemade jam? Or thought about it, but figured it was much too hard?

You’re in the right place! And I felt the same way as you a couple days ago before the ECHO experts taught me how to make jam for the first time!

Join me on the blog today in learning to make the best (seriously, I love this stuff!) homemade mango jam.  This is an easy step-by-step method for any experience level, and we’ll have lots of tips and tricks from experts along the way!

Let’s jump right in!

First, you’ll need lots of mangoes! Here’s what we started with.

THE RECIPE:

4 cups chopped mangoes

1/2 cup lemon juice

1/2 tsp butter

1 box Sure Jell (fruit pectin)

4 cups sugar

(This recipe yields approximately 7, 8 oz. jars of jam)

THE PROCESS:

Step One: Prep

Wash the mangoes and place a bag in the sink to collect scraps for composting.

Also collect and measure sugar, lemon juice, butter, and pectin. Set aside to combine in a later step.

Step Two: Peel

Peel all the skin off the mangoes either in a circular motion or in vertical slices. Collect the scraps in a bag for composting.

Step Three: Slice and Squeeze

Slice and squeeze the mangoes. Get as much fruit off the pit as possible. Collect it all in a bowl. It will all be mashed eventually so don’t worry about making it look nice!

Step Four: Begin boiling

Measure out 4 cups of chopped or mashed mango. The consistency is your choice. Keep in mind that big chunks will boil down. The ECHO experts prefer a chunky mango jam to a smoother version.

Combine mango, lemon juice, butter, and pectin in a large pot.

Bring it to a rolling boil.

What is a rolling boil?! It means the mangoes can be stirred and it will keep boiling instead of dying down like they would if they were just simmering.

Step Five: Add sugar

Once the mixture has begun boiling, stir in 4 cups of sugar.

Bring the new mixture back to a boil.

Let the jam mixture boil for 3 minutes. Seriously! 3 whole minutes. Set a timer!

It’s important to get this step right in order for the sugar to have the proper reaction that creates the jam consistency. Science says so, and so do the ECHO experts!

Step Six: Fill jars

After 3 minutes, ladle the jam into jars. This recipe should yield about 7, 8 oz. jars.

We recommend using a funnel! (Which you can purchase here).

Do not fill the jar to the brim. Leave about 1/4 of an inch of space at the top.

Lightly screw on caps.

Step Seven: Hot water bath

Submerge cans in a pot of boiling water.

To ensure they are properly sealed, boil for 10 minutes! Again, this is important. Set a timer for 10 whole minutes!

Step Eight: Remove, cool, and enjoy!

Carefully remove jars from boiling water. Jars will be hot. 

The experts at ECHO recommend a canning jar lifter. This is the best tool for taking the hot cans out of the boiling water safely.

Set them aside on the counter to cool. We suggest leaving them out overnight. Jars may make popping sounds- this is a good sign! It means they are sealing.

After jars have cooled,  keep them in a cool dry place and use within 18 months to 2 years! Consider labeling your new favorite jam with an “enjoy-by” date.

Once opened, store the jam in the refrigerator.

Enjoy!!

And there you have it! A simple eight-step process for mango jam that’s perfect for beginners or experts.

DIY Self-Watering Planter

ECHO has been teaching urban gardening techniques since the early 80’s when Co-founder Dr. Martin Price visited Guatemala City and was inspired by the acres and acres of usable rooftop space being wasted.

Shortly thereafter, Dr. Price set up the urban garden demonstrations that ECHO is well known for, including growing vegetables in discarded automobile tires. Some say that the most challenging part of growing gardens in containers is making sure that they receive adequate amounts of water at regular intervals.

Self-watering planters exist in all shapes, sizes and price points. ECHO Asia’s Patrick Trail shares his tips on building a self-watering container garden with easy-to-find or recycled materials.

Materials that you’ll need: 5-gallon bucket with lid, a length of PVC, an old t-shirt or cloth, a drill, some screws, a zip tie, and a plastic cutting tool.

Reducing Losses and Improving Quality – Solar Dryers at ECHO Asia

The ECHO Asia Impact Center has teamed up with the Horticulture Innovation Lab at University of California, Davis (UC Davis) to build and compare two solar dryers.

Fruits and vegetables have the potential to be profitable commodities for small-scale farmers, but have high risk. These crops are often harvested in high volume over a short period of time, when quality is high but prices are low. Rates of loss and waste in fresh produce can be quite high, especially in developing countries. Solar drying of fresh fruits and vegetables is a processing technique that preserves and extends food supplies, creates value from crop surpluses, empowers smallholder farmers with income and creates rural employment.

The Horticulture Innovation Lab at UC Davis was born out of the Horticulture Collaborative Research Support Program, or HortCRSP, a five-year program that has funded projects aimed at improving the livelihoods of impoverished smallholder farmers. Innovative new technologies, like low-cost solar dryers capable of raising the temperature above 100ºF, are a key part of this. The ECHO Asia Seedbank is one of seven sites around the world that have been chosen to build and run trials between two dryers. One is a traditional model designed by the United Nation’s Food and Agriculture Organization (FAO) in the 1980s, and the other a new UC Davis design.

The traditional FAO model is an indirect solar dryer, which means that the product won’t be dried by direct exposure to sunlight, but rather by air that is heated and drawn over it by convection. The new UC Davis design, by contrast, is both an indirect and direct solar dryer: hot air is drawn across the six-meter length of table and up the three-meter tall chimney, drying the product indirectly, but the trays lining the table are also exposed to direct sunlight.

The team assembled at the ECHO Asia Impact Center in Chiang Mai was composed of staff, several volunteers, a visiting expert from Kasetsart University in Bangkok, and Principal Investigator Lizanne Wheeler. They spent two days sourcing all materials required locally: wood (New Zealand pine); plastic (both clear and black; expensive); corrugated metal (the solar absorber); food-grade plastic netting (for trays); a piano hinge; and a staple gun. The chimney for the FAO model was brought from Bangkok.

After pre-fabricating as many parts as possible in Chiang Mai all the materials were transported to the ECHO Asia Seedbank outside Fang for assembly.

The result is two large drying apparatuses where before there was only hog manure and compost. Between the two they set up a weather station that will monitor wind velocity, wind gusts, hours of daylight, relative humidity, and ambient temperature. Preparations for trials on 140 kgs of tomatoes and 15 kgs of chillies have now begun, and these will be repeated in the cold and hot seasons when weather conditions are even more suitable for cooking.
