Moringa oleifera or Drumstick Tree can be grown easily with least maintenance.
Light: Full sun.
Moisture: Moderate water requirements. It is drought-tolerant once well established.
Soil: Fertile, slightly acidic, loamy and well-drained soils.
Prune regularly to promote regrowth and keep its shape in check. In cultivation, it is often cut back annually to 1-2 m and allowed to regrow so that the leaves remain within arm’s reach. Once monthly, feed the plant with slow-release granular fertiliser to stimulate growth and fruit production. Generally free from serious pests and diseases.
For subtropical and temperate regions: Hardiness: USDA Zone 9-11.
Moringa oleifera or Drumstick Tree is grown mainly in semi-arid, tropical and subtropical areas. This tree does not tolerate freezing or frost. Flowering begins within the first six months after planting. In seasonally cool regions, flowering only occurs once a year between April and June. In more constant seasonal temperatures and with constant rainfall, flowering can happen twice or even all year-round.
- Propagation: Easily propagated from seeds. Alternatively by stem cuttings of 1 m length and at least 4 cm diameter.
Usage: Moringa oleifera or Drumstick Tree is widely cultivated in tropical and subtropical areas where its young seed pods and leaves are used as vegetables.
Immature green pods are edible and often used in curries. They are eaten by sucking out their internal contents and the tough valves are discarded. Seeds inside mature pods can be eaten like peas or roasted like nuts. Flowers are also edible when cooked. Roots are shredded and used as a condiment like horseradish. Its highly nutritious leaves are cooked and used like spinach and can also be dried and crushed into a powder that is used in soups and sauces. Seed are also pounded and used to purify dirty or cloudy drinking water. Mature seeds contain about 25% oil that does not turn rancid and are used for cooking, lubrication and perfumery purposes. This beauty can be planted as a hedge for the provision of wind protection, shade and support for climbing garden plants.
