Propagation of Haworthia Scabra Haw. var. Johanii M.Hayashi
Haworthia scabra Haw. var. johanii M.Hayashi is a beautiful succulent plant that looks like a miniature aloe plant. Propagating this plant is easy and fun, and it will help you grow your collection quickly.
Propagation by Division
The most common propagation method for Haworthia scabra Haw. var. johanii M.Hayashi is division. When you propagate by division, you need to remove the offsets or pups growing from the base of the mother plant. It is best to wait until the offsets are at least one-third the size of the mother plant.
Use a sharp and clean knife or shears to cut the base of the pup as close to the mother plant as possible. Let the cut pup dry for at least 24 hours before you plant it in its own pot.
Propagation by Leaf Cuttings
You can also propagate Haworthia scabra Haw. var. johanii M.Hayashi by leaf cuttings. When you use this method, you will cut a leaf from the mother plant, let it dry for a few days, then place it in soil or a propagating mix.
The first step is to cut the healthy leaf from the bottom of the stem with a clean and sharp knife. The leaf must be at least 2-inches long. After the cutting, let the leaf dry for three to five days so that the wound can heal and prevent rotting when planted.
When the leaf is fully healed, prepare a well-draining soil mix such as perlite or sand. Place the leaf cutting in a pot, keeping it upright. Add a small amount of soil or propagating mix around the cutting, covering only the base of the leaf. On average, it takes two months for the leaf to root and produce a new plant.
Propagation by Seeds
If you want to propagate Haworthia scabra Haw. var. johanii M.Hayashi by seeds, you need to collect ripe seed pods from the mother plant during the summer. Let the seed pods dry and split to release the seeds. Sow the seeds in a tray or pot containing well-draining soil mix.
The seeds must be at least half-buried in the soil. Keep the soil moist until the seeds germinate, which usually takes up to three weeks, but it can take longer. Once the seeds germinate, remove the cover and begin to grow the seedlings under bright light.
Propagation of Haworthia scabra Haw. var. johanii M.Hayashi can be fun and rewarding. Choose the method that works best for you, and enjoy growing your own collection of beautiful succulent plants.
