Propagation
Seeds from dried tamarind blocks, or from fresh tamarind usually grow, but sow more than you want as germination can sometimes be poor. Steep the seed in tepid water for a few hours before sowing.
Sow in a shallow pot contaning a mixture of seed compost and grit, just cover the seeds and keep warm, preferably with bottom heat, at 20°C for at least 3 weeks.When shoots emerge, keep damp, in a warm light place but not in direct sunlight.
Tamarind can also be increased by taking cuttings of young shoots in the summer in a heated frame.
