How to Propagate Deutzia?
Deutzia can be propagated by semi-hardwood cuttings, softwood cuttings, or seeds. Key factors for successful propagation include maintaining a warm temperature, ensuring high humidity, and using well-draining soil. Cuttings are typically easier and more reliable than seeds, which can be variable in germination. It's important to consider the timing, with cuttings best taken in the late spring or early summer. Propagation of deutzia is generally straightforward, though some patience is needed for rooting. To propagate by cuttings: 1) Cut a 4-6 inch stem segment from a healthy deutzia plant. 2) Remove the lower leaves, dip the cut end in rooting hormone, and plant in a mix of peat and perlite. 3) Keep the medium moist and provide indirect light. 4) After 4-8 weeks, check for root development before transplanting.
