Propagation of Cistus villosus L. var. undulatus Gross.
Cistus villosus L. var. undulatus Gross. can be propagated through several methods:
Seed propagation
Seeds from healthy plants can be collected in the fall. The seeds can be stored in a dry and dark place until the spring. In March or April, the seeds can be sown in a seed-starting mix. The mix should be kept moist and warm, but not wet. The seeds should germinate in two to four weeks. The seedlings can be transplanted in individual pots when they have two or three pairs of leaves.
Cuttings propagation
Cuttings from healthy plants can be taken in the summer. The cuttings should be taken from the current year's growth. The lower leaves should be removed, leaving only a few pairs of leaves at the top. The cuttings should be dipped in rooting hormone and planted in a mix of peat and perlite. The mix should be kept moist, but not wet. The cuttings should root in four to six weeks and can be transplanted in individual pots.
Layering propagation
The layering method involves bending a low-growing branch of the plant towards the ground, where it is covered with soil. The soil should be kept moist. After a few weeks, roots should start to grow from the branch. Once the branch has developed enough roots, it can be separated from the parent plant and transplanted in a pot.
