How To Plant Moringa (Cultivation)

I could not believe myself the present interest of so many with the tree called “moringa,” as I received so many feedbacks after I wrote some articles about it and its economic and nutritional benefits. Believe it or not, one of my always read articles on this blog falls under tag moringa. Maybe because global trading is now pointing to organics and people these days are getting more health conscious. One of which is “how to plant moringa?

I have to admit that though have the knowledge, I am not yet an expert on moringa farming. Nonetheless, I knew one writer who has written a more precise suggestion and fit to where it most needed these days… “Africa.” Allow me to excerpt from the writings of Lowell J. Fuglie and K. V. Sreeja …

Quote:
Moringa oleifera (“Malunggay” in Philippine native language) is believed to be native to sub-Himalayan tracts of northern India but is now found worldwide in the tropics and sub-tropics. It grows best in direct sunlight under 500 meters altitude. It tolerates a wide range of soil conditions, but prefers a neutral to slightly acidic (pH. 6.3-7.0), well-drained sandy or loamy soil. Minimum annual rainfall requirements are estimated at 250mm with maximum at over 3,000mm, but in waterlogged soil the roots have a tendency to rot. (In areas with heavy rainfall, trees can be planted on small hills to encourage water run-off). Presence of a long taproot makes it resistant to periods of drought. Trees can be easily grown from seed or from cuttings. Temperature ranges are 25-35 degrees Celsius (0-95 degrees Fahrenheit), but the tree will tolerate up to 48 degrees in the shade and it can survive a light frost. Moringa seeds have no dormancy period, so they can be planted as soon as they are mature and they will retain the ability to germinate for up to one year. Moringa trees will flower and fruit annually and in some regions twice annually. During its first year, a Moringa tree will grow up to five meters in height and produce flowers and fruit. Left alone, the tree can eventually reach 12 meters in height with a trunk 30cm wide; however, the tree can be annually cut back to one meter from the ground. The tree will quickly recover and produce leaves and pods within easy reach. Within three years a tree will yield 400-600 pods annually and a mature tree can produce up to 1,600 pods.

IN THE NURSERY:
Use poly bags with dimensions of about 18cm in height and 12cm in diameter. The soil mixture for the sacks should be light, i.e. 3 parts soil to 1 part sand. Plant two or three seeds in each sack, one to two centimeters deep. Keep moist but not too wet. Germination will occur within 5 to 12 days, depending on the age of the seed and pre-treatment method used. Remove extra seedlings, leaving one in each sack. Seedlings can be out-planted when they are 60-90cm high. When out-planting, cut a hole in the bottom of the sack big enough to allow the roots to emerge. Be sure to retain the soil around the roots of the seedling.

To encourage rapid germination, one of three pre-seeding treatments can be employed:
1. Soak the seeds in water overnight before planting.
2. Crack the shells before planting.
3. Remove shells and plant kernels only.

IN THE FIELD:
If planting a large plot it is recommended to first plough the land. Prior to planting a seed or seedling, dig a planting pit about 50cm in depth and the same in width. This planting hole serves to loosen the soil and helps to retain moisten in the root zone, enabling the seedlings’ roots to develop rapidly. Compost or manure at the rate of 5kg per pit can be mixed with the fresh topsoil around the pit and used to fill the pit. Avoid using the soil taken out of the pit for this purpose: fresh topsoil contains beneficial microbes that can promote more effective root growth. The day before out planting, water the filled pits or wait until a good rain before out-planting seedlings. Fill in the hole before transplanting the seedling. In areas of heavy rainfall, the soil can be shaped in the form of a mound to encourage drainage. Do not water heavily for the first few days. If the seedlings fall over, tie them to stick 40cm high for support.

DIRECT SEEDING:
If water is available for irrigation (i.e., in a backyard garden), trees can be seeded directly and grown anytime during the year. Prepare a planting pit first, water, and then fill in the pit with topsoil mixed with compost or manure before planting seeds. In a large field, trees can be seeded directly at the beginning of the wet season.

GROWING FROM CUTTINGS:
Use hard wood, not green wood, for cuttings. Cuttings should be 45cm to 1.5m long and 10cm thick. Cuttings can be planted directly or planted in sacks in the nursery. When planting directly, plant the cuttings in light, sandy soil. Plant one-third of the length in the ground (i.e., if the cutting is 1.5m long, plant it 50cm deep). Do not over water; if the soil is too heavy or wet, the roots may rot. When the cuttings are planted in the nursery, the root system is slow to develop. Add phosphorus to the soil if possible to encourage root development. Cuttings planted in a nursery can be out-planted after 2 or 3 months.

SPACING:
For intensive Moringa production, plant the tree every 3 meters in rows 3 meters apart. To ensure sufficient sunlight and airflow, it is also recommended to plant the trees in an east-west direction. When the trees are part of an alley-cropping system, there should be 10 meters between the rows. The area between trees should be kept free of weeds.

Trees are often spaced in a line one meter or less apart in order to create living fence posts. Trees are also planted to provide support for climbing crops such as pole beans, although only mature trees should be used for this purpose since the vine growth can choke off the young tree. Moringa trees can be planted in gardens; the tree’s root system does not compete with other crops for surface nutrients and the light shade provided by the tree will be beneficial to those vegetables which are less tolerant to direct sunlight. From the second year onwards, Moringa can be inter-cropped with maize, sunflower and other field crops. Sunflower is particularly recommended for helping to control weed growth. However, Moringa trees are reported to be highly competitive with eggplant (Solanum melongena) and sweet corn (Zea mays) and can reduce their yields by up to 50%.

PINCHING THE TERMINAL TIPS:
When the seedlings reach a height of 60cm in the main field, pinch (trim) the terminal growing tip 10cm from the top. This can be done using fingers since the terminal growth is tender, devoid of bark fiber and brittle, and therefore easily broken. A shears or knife blade can also be used. Secondary branches will begin appearing on the main stem below the cut about a week later. When they reach a length of 20cm, cut these back to 10cm. Use a sharp blade and make a slanting cut. Tertiary branches will appear, and these are also to be pinched in the same manner. This pinching, done four times before the flowers appear (when the tree is about three months old), will encourage the tree to become bushy and produce many pods within easy reach. Pinching helps the tree develop a strong production frame for maximizing the yield. If the pinching is not done, the tree has a tendency to shoot up vertically and grow tall, like a mast, with sparse flowers and few fruits found only at the very top.

For annual Moringa types, directly following the end of the harvest, cut the tree’s main trunk to about 90cm from ground level. About two weeks later 15 to 20 sprouts will appear below the cut. Allow only 4-5 robust branches to grow and nib the remaining sprouts while they are young, before they grow long and harden. Continue the same pinching process as done with new seedlings so as to make the tree bushy. After the second crop, the trees can be removed and new seedlings planted for maximum productivity.

For perennial Moringa types, remove only the dead and worn out branches every year. Once in four or five years, cut the tree back to one meter from ground level and allow re-growth.

WATERING:
Moringa trees do not need much watering. In very dry conditions, water regularly for the first two months and afterwards only when the tree is obviously suffering. Moringa trees will flower and produce pods whenever there is sufficient water available. If rainfall is continuous throughout the year, Moringa trees will have a nearly continuous yield. In arid conditions, flowering can be induced through irrigation.

FERTILIZING:
Moringa trees will generally grow well without adding very much fertilizer. Manure or compost can be mixed with the soil used to fill the planting pits. Phosphorus can be added to encourage root development and nitrogen will encourage leaf canopy growth. In some parts of India, 15cm-deep ring trenches are dug about 10cm from the trees during the rainy season and filled with green leaves, manure and ash. These trenches are then covered with soil. This approach is said to promote higher pod yields. Research done in India has also showed that applications of 7.5kg farmyard manure and 0.37kg ammonium sulfate per tree can increase pod yields threefold.

PESTS 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 an 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 Noordia moringae and the scale insects Diaspidotus sp. and Ceroplastodes cajani are reportedly able to cause serious damage. Also mentioned as pests in India are Aphis craccibora, the borer Diaxenopsis apomecynoides and the fruit fly Gitonia sp. Elsewhere in the world, where Moringa is an introduced tree, local pests are less numerous.

HARVESTING:
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.

When producing seed for planting or for oil extraction, allow the pods to dry and turn brown on the tree. In some cases, it may be necessary to prop up a branch that holds many pods to prevent it breaking off. Harvest the pods before they split open and seeds fall to the ground. Seeds can be stored in well-ventilated sacks in dry, shady places.

For making leaf sauces, harvest seedlings, growing tips or young leaves. Older leaves must be stripped from the tough and wiry stems. These older leaves are more suited to making dried leaf powder since the stems are removed in the pounding and sifting process.

    I notice that the one I planted in my house compound just for my family use is not growing well. It is about 2 months old, 1ft high. The worrisome part is that the leaves are turning brown, some falling off. It is receiving enough daily water. What do you think is wrong? or what should I do to save it from total extinction?

    Thanks for your time.

    Dear John, The information, “daily water,” concerns me. Moringa roots will begin to rot after left standing in water for 3 days. My best guess is over watering is something to consider. I have found that daily watering is only necessary when the potted trees are outside in the direct sun over at least 80 degrees.

    Let the soil dry up but I have found the potted trees like a little moisture in the soil, so you don’t want it to get “bone dry,” for long.

    Don’t forget to eat those leaves that are dropping. Once you see them start to dry or turn yellow, go ahead and trim them.

    Keep your tree in a place that it can get the most sunlight possible. I have used grow lights, but the leaves grow larger and healthier with natural sunlight.

    Best Wishes

    It is (moringa) a very usueful plant but difficult to process the leaf under sun drying and in leaf-concentrate making.
    Let us discuss the use of non-solar dryers . Does oven drying of the leaves reduce the potency of the leaf-powder?

      pls e-mail me directly at denissalvatierra@yahoo.com for your suggestion and recommendations. I am at the moment seeking support for this advocacy as moringa is widely demanded these days for nutritious products, high end perfume/cosmetics raw materials, biofuel, etc. Philippine Government is promoting for moringa propagation as Philippine soil and climate is best to grow such plant.
