Propagation of Kedrostis hirtella (Naudin) Cogn.
Kedrostis hirtella (Naudin) Cogn. can be propagated by both seeds and cuttings.
Propagation by Seeds:
The easiest way to propagate Kedrostis hirtella (Naudin) Cogn. is through seed collection and sowing. The plant produces small, black seeds that can be collected in autumn, just before they drop from the plant. The collected seeds must be cleaned and stored in a cool, dry place.
The seed propagation process involves sowing the cleaned seeds in a well-draining potting mix at a depth of about 1 to 2 cm. The potting mix must be moist but not overly wet during the germination process. The seeds usually germinate within 3 to 4 weeks, and the seedlings can be transplanted to larger containers or directly into the garden bed once they are large enough to handle.
Propagation by Cuttings:
Kedrostis hirtella (Naudin) Cogn. can also be propagated by stem cuttings taken during the growing season. The cuttings should be at least 10 cm in length and should be taken from the plant's new growth, where the stems are soft and flexible.
The cuttings must be allowed to dry for a few hours to prevent the cut ends from rotting before planting. They can be planted directly in a well-draining potting mix and kept moist until the cuttings have developed roots and new shoots. The new plants can then be transplanted to larger containers or directly into the garden bed.
Propagation by seeds and cuttings are both successful methods of propagating Kedrostis hirtella (Naudin) Cogn. The plant is easy to propagate, and with the right care, the new plants can grow into healthy and beautiful plants.
