Seeds and propagation
Entandrophragma excelsum is propagated using seedlings or wildlings. Collect mature fruits from the tree or from the ground; dry them in sun and extract seeds by hand using a knife. There are 1200-1500 seeds per kilogram. Germination is very good and can attain 30-80% after 4-6 weeks from sowing. No pre-treatment required before sowing but the wings should be broken off. Seeds are susceptible to insect attack, therefore it is advisable to use ash for reducing insect damage. Stored in a cool place, seeds can retain viability for six months
Entandrophragma excelsum needs nurse trees in early stage and needs regular weeding at this stage. It can be planted as a shade tree i banana, coffee and tea plantation
