How to Propagate Colletia?
Colletia species are primarily propagated through semi-hardwood cuttings or seeds. Key factors for successful propagation include well-drained soil, consistent moisture, and bright, indirect light. Semi-hardwood cuttings should be taken from healthy plants in late summer. The difficulty level is moderate, with challenges including rooting hormone application and patience for slow root development. To propagate, take 4-6 inch cuttings, apply rooting hormone, insert into well-draining soil mix, keep conditions slightly humid, and wait for rooting before transplanting. Colletia benefits from bottom heat and avoiding waterlogged soil during the rooting process.
