Care in the first three years

For three years, keep the young palm shaded in summer, watered in dry spells and free of weeds.

Water. Irrigate in the dry months for at least the first two years (TNAU Agritech); where rain is scant or badly spread, a coconut needs water in long dry spells for life (ICAR-CPCRI).

Basin and drainage. Weed the pit, remove soil washed onto the collar in the rains, and widen the basin a little each year; as a guide, ICAR-CPCRI says it should reach a radius of 1.8 m from the trunk by the fourth year. In low-lying land, make sure rainwater drains away.

Mulch and manure. Spread husks (ICRAF) or fallen coconut leaves (ICAR-CPCRI) in the basin to hold moisture and keep weeds down, a hand's width from the stem (rule of thumb). Mix in well-rotted manure or compost when you widen the basin; for anything more, ask your local Krishi Vigyan Kendra (KVK).

Pests and diseases. ICAR-CPCRI names the rhinoceros beetle as the biggest problem for young palms: it bores into the collar and leaves V-shaped cuts in new leaves, and it breeds in rotting manure, compost and dead coconut logs, so keep these away. Bud rot, which rots the central spear leaf, is worst in the monsoon. If you see holes at the collar, a dying spear leaf or a foul smell from the crown, take clear photos or a sample to your local KVK or agriculture department, and do not spray anything without their advice.

Patience. ICAR-CPCRI says a tall-type palm gives its first nuts roughly 5–7 years after planting and a dwarf roughly 3–4 years after planting. There is no shortcut beyond a good seedling, full sun, enough water and early action against rhinoceros beetle (practical guidance).
