Most of the tree seeds need special pretreatment before sowing. A short note on seed pretreatment and nursery consideration are enclosed in the consignment upon purchasing seeds from TTSA. We encourage customers give all information on viability, pretreatment and storage prescriptions to the responsible seed handling staff at the nursery (or the seed store) to ensure seed viability is maintained. Upon request, TTSA can help regarding pretreatment for certain species, especially hard coated species, e.g. Acacia, Tamarindus, Afzelia, Julbernadia etc. See list of species below for further reading.
