Jatropha curcas grows almost anywhere , even on gravelly,
sandy and saline soils. It can thrive on the poorest stony soil.
It can grow even in the crevices of rocks. The leaves shed
during the winter months form mulch around the base of the
plant. The organic matter from shed leaves enhance earthworm
activity in the soil around the root-zone of the plants,
which improves the fertility of the soil.
Regarding climate, Jatropha curcas is found in the tropics and subtropics and likes heat,
although it does well even in lower temperatures and can withstand a light frost. Its water
requirement is extremely low and it can stand long periods of drought by shedding most
of its leaves to reduce transpiration loss. Jatropha is also suitable for preventing soil
erosion and shifting of sand dunes.
