- Remove the offsets from the main plant using a sharp knife or scissors.
- Prepare a well-draining potting mix and a pot that is slightly larger than the offset.
- Plant the offset in the potting mix and water it lightly.
- Place the pot in a warm and bright location, but out of direct sunlight.
- After a few weeks, the offset should start growing roots and new leaves.
Leaf Cuttings
Gasteria subverrucosa var. marginata can also be propagated using leaf cuttings. To propagate using leaf cuttings, follow these steps:
- Choose a healthy leaf from the main plant and remove it from the stem.
- Allow the leaf to dry for a day or two, until the cut end has formed a callus.
- Prepare a well-draining potting mix and a pot that is slightly larger than the leaf cutting.
- Plant the leaf cutting in the potting mix with the callused end inserted into the soil.
- Water the soil lightly and place the pot in a warm and bright location, but out of direct sunlight.
- The leaf cutting should start growing new roots and leaves after a few weeks.
Seeds
Propagation of Gasteria subverrucosa var. marginata can also be done using seeds. To propagate using seeds, follow these steps:
- Collect ripe seeds from the plant and allow them to dry out completely.
- Prepare a well-draining potting mix and a pot that is large enough for the seedlings.
