Propagation of Holodiscus dumosus var. glabrescens
Holodiscus dumosus var. glabrescens can be propagated through various methods including:
Seed Propagation
Seeds of Holodiscus dumosus var. glabrescens can be collected in the fall when they mature and become brown. The seeds can be sown immediately or stored in a cool, dry place until spring. The seedbed should be prepared by removing weeds, stones, and other debris and should be well-drained to prevent waterlogging. The seeds should be sown shallowly, covered with a thin layer of soil and kept moist until germination occurs. Germination can take several weeks to several months.
Cuttings Propagation
Holodiscus dumosus var. glabrescens can be propagated through softwood cuttings taken in the spring or hardwood cuttings taken during the dormant season. The cuttings should be 4-6 inches long and have at least 2-4 nodes. The basal end of the cutting should be treated with a rooting hormone and inserted into a well-draining rooting medium. The cuttings should be kept in a warm, humid environment with bright, indirect light until they develop roots. This can take several weeks to several months.
Division Propagation
Holodiscus dumosus var. glabrescens can be propagated through division in early spring before new growth begins. The plant should be carefully dug up and the root system divided into several sections, each with several shoots and roots. The sections should be replanted in well-draining soil and kept moist until they establish.
