Stem Cutting Propagation
The stem cuttings of Santolina chamaecyparissus L. are taken in late summer or early autumn when the plant is at its best. Cut about 5-6 inches of semi-hardwood stem cuttings from the parent plant. Remove the lower leaves from the cuttings and dip the base of the stem in rooting hormone powder.
Prepare a well-draining potting mix using a mixture of perlite, peat moss, sand, and compost in equal amounts. Plant the cutting about an inch deep in the potting mix. Keep the soil moist but not waterlogged and place the cutting in a partially shaded location.
Within two to three weeks, roots should appear, and the cutting can be transplanted into the ground or a container. It is suggested to fertilize the soil with a balanced fertilizer every three to four weeks for the first year.
