Harvesting of the leaves can begin three to four months after planting.

To harvest leaves with plenty of protein without the hard veins, harvesting must be done after every 30 to 40 days. Meanwhile, if there is no irrigation, the roots can take a longer time to grow. In this case harvesting has to be done after every two months especially in the dry season. There are two possible harvesting methods.
- Cutting of all the branches with leaves 50cm from the soil. The leaves are then cut off from the branches out of the farm. The green branches can be given to animals as fodder. This is the best method for two reasons: The plants are trimmed during harvesting. The leafing is vigorous and plenty.
- The other method is the cutting of leaves at the bud directly in the farm. Such harvesting is very fast but the leaves grow back much slower and lesser in quantity and the plant does not ramify. This method must be accompanied by a two times trimming per year. This trimming is done on the stem 20 cm from the soil.
When harvesting pods for human consumption harvest when the pods are still young (about 1cm in diameter) and snap easily. Older pods develop a tough exterior, but the white seeds and flesh remain edible until the ripening process begins.

Pet and diseases
Moringa is resistant to most pests. In very water-logged conditions, Diplodia root rot can occur. In very wet conditions, seedlings can be planted in mounds so that excess water is drained off. Cattle, sheep, pigs and goats will eat Moringa seedlings, pods and leaves. Protect Moringa seedlings from livestock by installing a fence or by planting a living fence around the plantation. A living fence can be grown with Jatropha curcas, whose seeds also produce oil good for soap-making. For mature trees, the lower branches can be cut off so that goats will not be able to reach the leaves and pods. Termites can be a problem, especially when cuttings are planted.

Among approaches recommended to protect seedlings from termite attack :
- Apply mulches of castor oil plant leaves, mahogany chips, tephrosia leaves or Persian lilac leaves around the base of the plants.
- Heap ashes around the base of seedlings
- Dry and crush stems and leaves of lion's ear or Mexican poppy and spread the dust around the base of plants.

In India, various caterpillars are reported to cause defoliation unless controlled by spraying. The budworm and the scale insects are reportedly able to cause serious damage. Also mentioned as pests in India are the borer and the fruit fly. Elsewhere in the world, where Moringa is an introduced tree, local pests are less numerous.

Do not spray Moringa leaves with chemical pesticides because they will always have residues since the leaves are harvested so very often and these pesticides are dangerous to the body.

Seed production
It is preferable for a farmer to produce his own seeds if he wants to increase the size of his farm. The Moringa tree whose leaves are being harvested cannot produce seeds anymore. It is necessary to have some plants for seeds. For plants to produce seeds, planting should be well spaced for up to three to five meters apart. The leaves must not be harvested and the seeds are ready for harvesting when the fruits are brown and dry.

The brisk business in Moringa
Though Moringa is just in it early stage in Cameroon, there are already several money making avenues in this sector.
1-The sale of seeds
The sector can be very profitable in the southern part of Cameroon where Moringa is still not highly cultivated but where several farmers have already started its production. Seeds from the Sahel region are highly solicited with a dozen at a cost of 2500Cfa francs. For a hectare of land taking about 400 plants, 500 seeds would cost about 104000 Cfa francs. Sales of the seeds for over 10 hectares of land will bring in over 1m Cfa francs. Your expenditure is negligible especially if you are not travelling and have somebody who does the expe-dition. 5000 seeds of Moringa weigh approximately 6kg.

2- The sale of plants
Some people like to buy the plants directly from the nurse-ries because of time constraints. In Yaounde, a Moringa plant cost 2500 Cfa francs. If you sell 1200 plants which is the quantity needed to plant 3 hectares of land, you will have 3 000 000 Cfa francs. Even if you spend 1m Cfa francs to produce these plants, you will still make profit.

3- Sale of leaf powder
Moringa leaf powder is selling presently like hot cake for those who have various health problems and those who just what to keep their bodies fit. A 200g package of the product is generally sold at 5000Cfa francs in Yaounde. A kg of the product can give about 25000 Cfa francs. To have an attractive packaging the powder can be put in a small box with a hermetic lead sold in supermar-kets. You can buy your own powder from trustworthy producers in the Sahel region if you are unable to produce yours. It is re-packaged before it is sold. Demand is very high and the producers and middlemen are making brisk business.

4- Feeding of animals at a lower cost
LesThe stems of Moringa have a lot of proteins and good for the feeding of animals. Some farmers who gave their fowls maize and Moringa obtained the same results as those with classical feed. With the high cost of feed in poultry production, one would imagine the high profit made by those who produce Moringa to incorporate in the feeding of poultry.

Process of making powder
- As soon as possible after the harvest (the same day) the leaves are laid out to dry in the drying workshop;
- 2 days after, the folioles are separated from the petioles and set back out to dry;
- After 3 to 4 days of additional drying, collect the dried leaves and pound in mortars;
- The powder is then sieved;
- After sieving, the powder is packaged in transparent plastic bags closed with a knot.
