Propagation of Acalypha decumbens Thunb.
Acalypha decumbens Thunb. can be propagated through several methods:
1. Seeds
Seeds are the easiest way to propagate Acalypha decumbens Thunb. They are usually collected in early fall and sown in a seedbed. The seedlings should be kept in a warm and humid place until they are ready to be transplanted into individual pots.
2. Stem Cuttings
Stem cuttings can also be used to propagate Acalypha decumbens Thunb. Cuttings should be taken from the plant in late spring or early summer. They should be about 6 inches long with at least two nodes. Remove the leaves from the bottom node and dip the stem in rooting hormone. Plant the stem cutting about an inch deep in a pot filled with a well-draining soil mix. The pot should be covered with clear plastic and placed in a warm, bright place. After a few weeks, the cutting should start to root. Once the roots have developed, the plastic covering can be removed, and the cutting can be transplanted into a larger pot or directly into the garden.
3. Division
Division is another way to propagate Acalypha decumbens Thunb. It can be done in late winter or early spring when the plant is dormant. Dig up the plant and separate the root ball into several sections using a sharp knife. Each section should have several stems and roots. Replant the divisions in individual pots or directly in the garden.
