Propagation of Kalanchoe Rotundifolia (Haw.) Haw. Forma Peltata Raym.-Hamet ex R.Fern.
Kalanchoe rotundifolia (Haw.) Haw. forma peltata Raym.-Hamet ex R.Fern. can be propagated from stem cuttings, leaf cuttings, and offsets.
Propagation from Stem Cuttings
Stem cuttings are the most common way of propagating Kalanchoe rotundifolia (Haw.) Haw. forma peltata Raym.-Hamet ex R.Fern. To propagate from stem cuttings, select a healthy stem with no flowers or buds, and cut it with a sharp, sterilized scissors or knife. Allow the cutting to form a callus by setting it aside in a dry place for a few days. Once the callus has formed, plant the cutting in well-drained soil and water it sparingly. Keep it in a bright, warm location, but away from direct sunlight. After a few weeks, the cutting will produce roots.
Propagation from Leaf Cuttings
Kalanchoe rotundifolia (Haw.) Haw. forma peltata Raym.-Hamet ex R.Fern. can also be propagated from leaf cuttings. To do this, select a healthy leaf with a short stem attached. Cut the leaf and its stem cleanly from the plant, and let it dry for a couple of days. Plant the leaf cutting in well-drained soil with the stem buried in the soil, and water sparingly. Keep it in a well-lit place with no direct sunlight. After a few weeks, the cutting will produce roots.
Propagation from Offsets
Offsets are small plantlets that grow from the base of the mature Kalanchoe rotundifolia (Haw.) Haw. forma peltata Raym.-Hamet ex R.Fern. plant. These can be gently removed from the mature plant and planted in their own pots. Make sure they have enough access to nutrients and light to support their growth.
