How to Propagate Sempervivum: Leaf Cuttings and Division Both Root Easily

Sempervivum is a must-have for many beginner succulent growers. Below we will discuss with everyone how to propagate Sempervivum. We hope this experience can help with your Sempervivum care.

Sempervivum Propagation Method: Leaf Cuttings

Lay a complete, mature leaf flat on moist sandy soil, leaf surface facing up and leaf underside facing down. There is no need to cover it with soil. Place it in a cool, shaded spot. After about 10 days, small leaf clusters and new roots will grow from the base of the leaf. Bury the root system in the soil. After that, let it get plenty of sunlight, water and fertilize appropriately, and it will gradually grow into a robust new plant.

Sempervivum Propagation Method: Stem Cuttings

You can use a single leaf, an offset branch, or a top branch. The length of the cutting taken is not restricted, but the cut end must dry out, then remove the lower leaves before inserting it into a sand bed. After insertion, roots generally form in about 20 days. The cutting medium must not be too wet, otherwise the cut end easily turns yellow and rots. When the roots are 2-3 cm long, pot it up. Leaf cuttings can also be used.

Sempervivum Propagation Method: Division

It is best to do this in spring. Cuttings are commonly used for propagation. Indoor cuttings can be taken in all four seasons, with August to October being better, as roots form quickly and the survival rate is high. For cuttings you can use a single leaf, an offset branch, or a top branch. The length of the cutting taken is not restricted, but the cut end must dry out before inserting it into a sand bed. After insertion, roots generally form in about 20 days.

Sempervivum Propagation Method: Pest and Disease Control

Rust, leaf spot, and root-knot nematodes are common problems. You can spray 75% chlorothalonil wettable powder at 800 times dilution for control. For root-knot nematodes, use 3% carbofuran granules for control. Among insect pests, the black vine weevil is a problem; spray 25% carbaryl wettable powder at 500 times dilution to kill it.

The main propagation methods for Sempervivum of the Crassulaceae family are leaf cuttings, stem cuttings, division, and so on. Whether it is a new plant or an old plant bought without a pot, do not water it right after planting; at most, spray a little water on the leaves.
