ShapeThis evergreen is dense, round, and mounded.
LandscapeIt is commonly used for accent features, massing, specimen, border, bonsai and hedges. For restoration, it can be used for slopes and banks as it is dense, multi-stemmed and compact. It is also used for winter gardens as its berries are persistent throughout the winter season, giving it seasonal interest. Wildlife such as songbirds, bees, and other pollinators tend to enjoy the small black berries.
PropagationThe Soft Touch Japanese Holly is propagated depending on the type of cutting preferred, whether it’s soft wood (in summer or late fall), or hardwood (winter time when shrub is dormant). For softwood cuttings, make a 0.6 cm cut below the leaf node, for hardwood cuttings cut above or below the bud union. Once either or is completed, make a container with soil media and sand. Then, add rooting hormone on the cut end and plant in the pot. Make sure to keep the cutting moist and in indirect light. Another option is seed propagation, first remove the skin of the berries. Then, rinse the seed in cold water and plant in a big flat with soilless potting medium. Next, cover the flats with a weather protection tarp to protect from winter weather. In the spring, germinating can occur, if not then leave them through another winter. This seed propagation process can take up to 16 months to 3 years.
