How to propagate Sempervivum
Do you know about this? Let's learn about the propagation methods of Sempervivum, including how to propagate Sempervivum and the green plant flower aspects of its propagation techniques.
The Sempervivum we usually refer to is a general term for plants in the Sedum family, Sempervivum genus. Sempervivum is very easy to propagate, as its leaves can root when they fall on the soil surface. It can be propagated using a single leaf, lateral branches, or top branches. Sempervivum plants are native to Central America and are now distributed from Mexico to South America. Common species include Sempervivum pieroti, Sempervivum blackhead, Sempervivum teyuscum, Sempervivum kikutii, Sempervivum 'Amakusa', Sempervivum 'Moonlight', Sempervivum 'Ebony', and Sempervivum 'Moss'. Below is a detailed introduction to the propagation methods of Sempervivum.
1. Propagation Season
Propagation can be done throughout the year, but it is suitable to do so in spring and autumn. The best time is from August to October. By this time, the leaves and branches on the mother plant have accumulated a large amount of nutrients after growing in spring and resting in summer. Propagation in autumn results in the fastest rooting and easiest survival.
2. Cutting Propagation Method
1. Selecting and preparing cuttings
Select healthy and robust suckers or top branches, cut them, soak the bottom cut ends in rooting powder, then air-dry until the wound surface is dry, and remove the lower leaves.
2. Preparing the growing medium
The growing medium should be a fertile sandy loam with good drainage, which can be a mixture of decomposed leaf soil, garden soil, coarse sand, and a small amount of bone meal.
3. Propagation process
Water the growing medium thoroughly before propagation, keeping it slightly moist but not too wet to avoid rotting the cut ends. Insert the cuttings directly into the medium.
4. Post-propagation care
After propagation, maintain a suitable environment. Usually, roots will form within 15 to 20 days, and once the roots are 2 to 3 centimeters long, they can be transplanted into pots.
3. Leaf Propagation Method
1. Selecting and preparing leaves
Remove large, plump, and healthy mature leaves, and let them dry in a shaded and well-ventilated area for 1 or 2 days, or expose them to the sun for 5 to 8 minutes before propagation.
2. Preparing the soil
Prepare sandy soil or vermiculite as the growing medium, and water it thoroughly before propagation.
3. Propagation process
Place the leaves flat on the sandy soil with the upper side facing up and the back side facing down.
4. Post-propagation care
After propagation, place the leaves in a shaded and well-ventilated area, maintaining a suitable temperature of 20 to 24°C. If the leaves do not shrink after 7 to 10 days, it indicates that they have survived, and soon fine roots will grow, followed by new buds. At this point, you can start watering and then cover the fine roots with soil, and provide normal care in a sunny location.
