African blackwood (Dalbergia melanoxylon) is a small, slow-growing legume native to seasonally dry savannas and woodlands across Africa. While seeds germinate readily without pre-treatment at relatively modest rates of 50-60%, the species faces significant conservation challenges due to overharvesting and low natural regeneration. Careful moisture management and seed viability screening are critical factors for successful propagation.
Before sowing
Pre-treatment is not necessary; seeds extracted from pods germinate readily
Sowing
What to expect
Tips
Keep seedlings in shade for 2 weeks after sowing, then move to full sun. Maintain consistently moist (not wet) soil throughout germination. Avoid crowding—space seedlings individually to prevent yellowing. Transfer to individual pots after 4-5 weeks. Seedlings require intensive weeding as they do not compete well with other plants. Store seeds with low moisture (9-12%) at 3°C for long-term viability; avoid storage longer than 1 year as viability declines significantly. Remove abortive and insect-damaged seeds before sowing to improve germination rates.
