Dracaena angolensis is can be propagated from seed sown in spring or summer, or by lifting and dividing clumps and replanting rhizomes. It can also be propagated through leaf cuttings, which is a moderate method requiring controlled conditions. Cut the leaves into 1 cm pieces, sterilize them and place them on a growth medium to promote root growth and plant development. Keep at standard conditions for 4-5 weeks to induce roots, then increase daytime temperature to 37°C to trigger shoot growth. Multiple shoots form at higher rooting hormone concentrations. After 5 weeks, separate the plantlets, harden them in soil for 2 weeks, and then transfer them to pots. This method works best any time with controlled conditions. It is best to use a rooting hormone to improve shoot formation. Once potted up, the plantlets are ready to be gradually acclimated to outdoor conditions.
