How to Propagate Spindle trees?
Propagation of spindle trees can be achieved by seed sowing, softwood cuttings, or semi-hardwood cuttings. Seeds require cold stratification to germinate. Cuttings are more successful when taken in late spring to early summer. Key factors include moist, well-draining soil, indirect light, and maintaining temperatures around 70-75°F. Special considerations involve the pre-treatment of seeds and the use of rooting hormones for cuttings. This species has moderate difficulty due to germination and rooting challenges. To propagate:
1.For seeds:
a. Collect seeds in autumn.
b. Stratify seeds by chilling them in refrigeration for 2-3 months.
c. Sow in a seed-starting mix, lightly covering with soil.
d. Keep moist and in indirect light until germination.
2.For cuttings:
a. Take 4-6 inch cuttings from healthy, non-flowering stems.
b. Remove lower leaves and dip the cut end in rooting hormone.
c. Insert into a mix of peat and perlite or sand.
d. Cover with a plastic bag to retain humidity and place in indirect light.
e. Keep the medium lightly moist until roots develop.
