The Moringa family (Moringaceae) has one genus, Moringa, with 13 species. Moringa
oleifera is the most widely cultivated species, grown throughout the tropics as a multipurpose
food tree. More than 70 cultivated varieties have been developed in India.
4-40 years, depending on cultivar.
Rapid, usually 10' a year. This tree can grow 20' a year in favorable conditions.
Small, yellow-white, sweetly fragrant, clustered. The flowers and buds are edible, but act
as a diuretic in large amounts.
Twice a year or more in non-freezing regions: late fall to early winter and late spring to
Years before fruiting:
This tree fruits in its first year. Flowers appear 8 months after planting.
A very long, slender, ribbed pod containing round, edible seeds. The dried mature seeds
are dark brown, round, with 3 white wings and are composed of 38-40% oil. For some
cultivars, the fruit is bitter and inedible in later years, causing the plant to be grown
as an annual.
Months for fruit to ripen:
2-4, depending on cultivar.
Storage after harvest:
Store mature pods in a dry space.
The green, oval leaflets are edible. The tree provides light to light-medium shade.
No thorns. New stems are slender and brittle, but become stronger in succeeding years.
The trunk, with whitish-gray, corky bark, becomes more cold hardy with age.
The tree grows a large taproot. The thick roots are edible and are a substitute for
horseradish. They are prone to root rot in waterlogged soil.
The flowers attract bees and butterflies. The seeds attract mammals.
Toxic / Danger:
The bark is mildly poisonous to humans. Eating more than two dried seeds can induce a
Southern foothills of the Himalayas in northwest India. The plant has been in use more
than 4000 years.
Cultivation and Uses
USDA hardiness zones:
9-10. Protect from freezes. The plant will regrow from its roots if well mulched. It may lose
leaves below 40°F.
Moringa needs extra water or afternoon shade above 90°F.
Dig a hole 1-2' deep and as wide, where the mature Moringa tree should grow. Make sure it
is well draining. Refill the hole with dirt and plant unsprouted seeds in the center, no
deeper than 1/2". Seed germination rate decreases with age and you may want to plant two
or three seeds per hole.
Plant as soon as possible after the last frost in late winter or early spring so the roots
will have time to become well established before the next winter freeze.
Young seedlings do not transplant well because their roots are fragile. If more than one
seed sprouts in the same hole, cut the weaker ones off at ground level. Pulling a seedling
out will damage the roots of the one remaining.
Seeds watered daily will often sprout in one week. Seedlings should be watered moderately,
every day until the trunk becomes woody. The soil should be dry the next morning to prevent
root rot. Yellow leaves on seedlings are a sign of insufficient water.
The young seedlings must be protected by 18" high fencing so they will not be eaten by
Moringa trees grown for food can be spaced 6' apart. As an ornamental screen they are
spaced 12' apart.
The tree can be grown in a large pot and moved inside in the winter.
This tree is very tolerant of any well drained soil, but does better in sandy soil with moderate
organic content. A soil pH of 6.3-7.0 (slightly acidic to neutral) is ideal.
Unnecessary because of rapid growth.
Water after becoming established:
once or twice a month depending on
temperature. This is a low water plant.
Apply organic mulch, inside the drip line and 8" away from the trunk, in late fall to protect
roots from freezes.
First Year Care:
To encourage the tree to grow rapidly, remove all fruit when very small in the first year.
Growing fruit takes energy away from developing the trunk and branches.
When growing as an edible leaf source, pinch off the top leader branch when the sapling
is two feet tall. This will encourage side branching and produce more leaves within reach.
As an edible seedpod source, the tree is often pulled up at the end of the year and new
seeds planted in the spring.
When used as an edible leaf source, cut the main trunk to a three foot stump every spring
to keep the tree height under control for leaf harvesting. When used as an ornamental, do
not prune until the first winter, then cut off all branches above head height to encourage
branching and a wider tree form. After the last freeze in spring, cut off any dead wood.
Leaf and seedpod drop in fall.
Rooted cuttings at least 36" long and 1.5" in diameter, or seed. Refrigerating or freezing
a seed will kill it.
A shade tree or food source. As a shade tree, it will attain a 40' height within four years
with a trunk up to 1.5' in diameter.
Many parts of the plant are edible, especially the highly nutritious leaves. Used raw
in salads, they taste similar to watercress or radicchio. Lightly cooked and added to chili,
omelets, stew or soup, they taste like a nutty flavored spinach. While they contain oxalates,
the oxalates are non-soluble, cannot contribute to kidney stones, and provide flavor without
The leaves have seven times the Vitamin C of oranges, four times the vitamin A of
carrots, three times the potassium of bananas, at least twice the calcium of milk and two
times the protein of yogurt. Teas made from the flowers or leaves have medicinal uses.
In commercial cultivation, the trees are used to produce either leaves or seedpods, but
Young small seedpods can be used raw in salads or cooked like green beans. Older green
pods, with the outer stringy coat scraped off, need longer cooking and have an asparagus
Pressing the seeds produces a non-drying, clear, odorless oil called Ben Oil, used for
cooking and as a machine lubricant. The inedible seed cake remaining after oil extraction
is used as a plant fertilizer.
Cuttings and branches are used as livestock feed.
The wood is too weak for construction but is good firewood. A blue dye can be made from
Other names are Miracle Tree, Horseradish Tree and Drumstick Tree.
Some cultivars are grown for their leaves, others for their oily seeds. Check the
characteristics of the plant you will be purchasing.
