Propagation of Acalypha amentacea Roxb.
Acalypha amentacea Roxb. can be propagated through a variety of methods.
Seeds
The plant produces seeds, which can be collected and sown into a well-draining potting mix. The seeds should be lightly covered with soil and kept moist until they germinate.
Cuttings
Softwood cuttings can be taken from the plant in spring or early summer. Cuttings should be taken from the tips of healthy, young stems, and should be approximately 5-7cm in length. The bottom leaves should be removed to create a bare stem, and the cutting should be placed in a well-draining potting mix. Keep the cutting moist and in a humid environment until it roots and begins to produce new growth.
Air Layering
Air layering can also be used to propagate Acalypha amentacea Roxb. This method involves making a small cut in a stem, and then wrapping it with sphagnum moss and plastic. This creates a humid environment for roots to grow. Once roots have formed, the stem can be cut below the air layer and potted up in well-draining soil.
