Moringa oleifera is a fast-growing, short-lived, drought-tolerant tree from northern India, widely grown across the tropics for its edible leaves and pods. The key to growing it is warmth, full sun and well-drained soil, since roots rot in waterlogged conditions and it does not tolerate frost.

About

Moringa oleifera is a short-lived, fast-growing, drought-resistant tree of the family Moringaceae, native to northern India and used extensively in South and Southeast Asia. Common names include moringa, drumstick tree (from the long, slender, triangular seed-pods), horseradish tree (from the taste of the roots, which resembles horseradish), ben tree (for its oil), or malunggay (as known in maritime or archipelagic areas in Asia).

It is widely cultivated for its young seed pods and leaves, used as vegetables and for traditional medicine. It is also used for water purification.

How to grow it

The moringa tree is grown mainly in semiarid, tropical, and subtropical areas, corresponding in the United States to USDA hardiness zones 9 and 10. It tolerates a wide range of soil conditions, but prefers a neutral to slightly acidic (pH 6.3 to 7.0), well-drained, sandy or loamy soil. In waterlogged soil, the roots have a tendency to rot. Moringa is a sun- and heat-loving plant, and does not tolerate freezing or frost. Moringa is particularly suitable for dry regions, as it can be grown using rainwater without expensive irrigation techniques.

Safety

Toxicity data in humans are limited, although laboratory studies indicate that certain compounds in the bark and roots or their extracts may cause adverse effects when consumed in excess. Supplementation with M. oleifera leaf extract is potentially toxic at levels exceeding 3,000 mg/kg of body weight, but safe at levels below 1,000 mg/kg. A study on albino mice found that high levels (>5,000mg/kg) of consumption could impair renal function.

M. oleifera may interfere with prescription drugs affecting cytochrome P450 (including CYP3A4) and may inhibit the antihyperglycemic effect of sitagliptin.

Where it grows

The moringa tree is not affected by any serious diseases in its native or introduced ranges. In India, several insect pests are seen, including various caterpillars such as the bark-eating caterpillar, the hairy caterpillar, or the green leaf caterpillar. Budworms from the Noctuidae are known to cause serious defoliation. Damaging agents can also be aphids, stem borers, and fruit flies. In some regions, termites can also cause minor damage. If termites are numerous in soils, insect-management costs are not bearable.

Uses

M. oleifera has numerous applications in cooking throughout its regional distribution. Edible parts of the plant include the whole leaves (leaflets, stalks and stems); the immature, green fruits or seed pods; the fragrant flowers; and the young seeds and roots.
