The seeds are raised in a nursery and when the seedlings are about 5 cm in diameter, they are grafted with buds from high yielding varieties. The trees are grown in rows at an interval from 4-6 m. A tree starts producing rubber when it is about 7 years old. During this time, the trees must be well protected from pests, weeds and diseases and must be regularly fertilised. Rubber cultivation is a labour intensive job and requires a large and skilled manpower.
