Propagation of Hemiptelea davidii
Propagation of Hemiptelea davidii can be done through seeds and cuttings.
Propagation through seeds
The seeds of Hemiptelea davidii can be collected in the fall when they are mature, and stored in a cool, dry place until spring. Before sowing the seeds, they need to be cold stratified for 60-90 days to break the seed dormancy. This can be done by placing the seeds in moist sand or vermiculite and storing them in a refrigerator. Once the stratification period is over, the seeds can be sown in pots or trays filled with well-draining potting mix, and kept in a warm, bright location with consistent moisture until they germinate. The seedlings can then be transplanted when they are large enough to handle.
Propagation through cuttings
Hemiptelea davidii can also be propagated through softwood or semi-hardwood cuttings taken in the summer. Select healthy stems with no flowers or buds, and make a clean cut just below a node. Remove the lower leaves and dip the cut end of the stem in rooting hormone powder. Insert the cutting into a pot filled with a rooting mix of sand or vermiculite, and keep it in a warm, bright location with high humidity until roots develop. Once the roots have established, the cutting can be transplanted into a larger container or planted out in a permanent location.
