Propagation of Lobostemon glaber
Lobostemon glaber (Thunb.) A.DC. is a hardy succulent plant that is relatively easy to propagate. There are different methods of propagation including division, stem cutting, and leaf cutting.
Division
Division is one of the easiest ways to propagate Lobostemon glaber. It involves dividing the plant into two or more parts, each with its own root system. This can be done when the plant becomes too large for its pot or when it has outgrown its current location.
To divide the plant, the soil around its root system must be moist. The plant is then carefully lifted from the soil and gently separated into two or more parts. Each part should have a good root system. The divided plants should then be planted in individual pots.
Stem Cutting
Stem cutting is another method of propating Lobostemon glaber. This method is best done in the spring or summer when the plant is actively growing. The stem cutting should be about 10cm long and should be taken just below a leaf node.
The cutting should be left to dry for a day or two before it is planted. When planting, the cutting should be inserted into moist soil up to the first leaf node. The soil should be kept moist and the cutting should be kept out of direct sunlight until it develops roots. After roots have formed, the cutting can be moved to a larger pot or planted in the ground.
Leaf Cutting
Leaf cutting is a less common method of propagating Lobostemon glaber. It is however, still an effective method. To do this, a healthy leaf should be taken from the parent plant.
The leaf should then be placed in moist soil with its end buried in the soil. It should be kept in a shaded area and the soil should be kept moist. After a few weeks, roots will start to form and a new plant will start to grow. The plant can then be transplanted to a larger pot or planted in the ground.
