Germination Information

Pre-treatment: Seeds are stored in cool-dry conditions with temperatures of approximately 50° F and relative humidity of 20 to 30%. Cuttings are treated with Dip 'n Grow Rooting Hormone #1 (IBA/NAA) diluted to 1250PPM (20:1), debudded and defoliated, except for 4 upper leaves. Cutting ends are retrimmed, prior to sticking.

Establishment: Seeds germinate 10 days after sowing. Seedlings are transplanted 15 days after germination to individual containers. It is important to keep seedlings evenly moist throughout growth. Do not allow to dry out. Cuttings are taken in the morning to keep turgid and fresh. Pruners are sterilized with isopropyl alcohol between cuttings.
