Germination Information
Pre-treatment: Cuttings are 15 to 20 cm in length and 7 mm in caliper. They are placed in a 2 minute fungicide bath to remove surface pathogens and treated with 1000 ppm liquid IBA. They are then struck in a mist bed with at least 2 nodes below the surface of the rooting media.
Establishment: Cuttings can be either spring hardwood or summer softwood stem cuttings. Hardwood tip cuttings are collected before bud break, while softwood cuttings can be collected any time of year after flowering.
