Care in the first three years

In the first three years the main jobs are keeping water away from the stem, watering in dry spells, protecting the young plant from frost and light shaping.

Year 1

The seasons below follow the north Indian year; where the rains come earlier or later, shift the timings to match.

Watering depends on soil, weather, plant age and recent rain. Water the root zone when it begins to dry, then let excess water drain away. Reduce watering during cool or rainy weather; do not follow a fixed litre schedule if the soil is still wet. None of our sources gives a watering schedule for a home moringa tree (TNAU's commercial annual crop is irrigated every 10–15 days according to soil type).

• Monsoon (Jul–Sep): Shape the soil so that water drains away from the stem; water only in long dry breaks.
• Post-monsoon (Oct–Nov): Mulch with dry grass or leaves (about 5–8 cm is our rule of thumb), kept off the stem.
• Winter (Dec–Feb): Where winters bring frost, cover the sapling with a jute or old-cloth hood on nights when frost is forecast (practical guidance). Water sparingly; cold, wet soil invites root rot.
• Spring and summer (Mar–Jun): The most demanding time for a young plant. Check the soil more often and water deeply when the root zone dries, in the morning or evening.

Year 2

Add well-rotted farmyard manure or compost around the tree in the monsoon (practical guidance). Water deeply in long dry spells and less after rain. Cover it on very cold nights while it is still small. If frost kills the tops, wait until the cold has passed, then cut back to live wood; ICRAF notes that moringa quickly sends out new growth when cut, or from the ground when frozen.

Year 3

Light shaping after the rains; water only in long dry spells. Dropping leaves in a dry spell is normal.

Pests and pruning

Watch for the hairy caterpillar (Eupterote mollifera), which ICRAF says causes defoliation. In a home garden, start with non-chemical steps: check the trunk and leaves regularly and remove caterpillar clusters by hand, wearing gloves, because the hairs can irritate skin (practical guidance). TNAU's commercial crop guide lists insecticides for farm pests such as the pod fly and leaf caterpillars; do not copy farm doses into a home garden. If an infestation is heavy, ask your local Krishi Vigyan Kendra (KVK) or horticulture office for current advice.

Pruning: for a tree form, remove only crossing or damaged branches. For commercial perennial moringa, TNAU Agritech describes medium pruning of shoots, about 70 cm from the tip, to regulate flowering; the yield it reports with this (37 kg per tree) is a farm figure, not a guarantee for a backyard tree.
