Seed Propagation
Propagation of Pelea clusiifolia Gray through seeds is a simple and easy process. The seeds are usually harvested from ripe fruit. The fruit is removed and the seeds are extracted from the pulp. The seeds are then soaked in water for several hours to soften the seed coat. The softened seed coat is then removed, and the seeds are sowed immediately in a well-drained potting mix. The seeds should be kept moist until they germinate, which usually takes about 2-3 weeks. Once the seedlings are big enough, they can be transplanted into individual pots.
Cuttings Propagation
Pelea clusiifolia Gray can be propagated through cuttings. The cuttings should be taken from semi-ripe stems, which are neither too soft nor too woody. The stem should be cut at an angle, and the leaves should be removed from the lower half of the cutting. The cutting should then be dipped into rooting hormone and planted in a well-drained potting mix. The pot should then be covered with a plastic bag to retain moisture. The cutting should root within 2-3 weeks. Once the cutting has rooted, the plastic bag can be removed and the plant can be transplanted into a bigger pot.
Air Layering Propagation
Air Layering is another method of propagating Pelea clusiifolia Gray. This method is used for larger plants. In air layering, a stem is cut partially through, and the cut is covered with a rooting hormone and wrapped with damp sphagnum moss. The moss is then covered with plastic wrap to keep it moist. The roots will develop within 4-6 weeks. Once the roots have developed, the stem can be cut below the rooted area and planted in well-drained potting mix.
In conclusion, Pelea clusiifolia Gray can be propagated through different methods including seed propagation, cuttings propagation, and air layering propagation. These methods are easy and simple, and the plant can be propagated successfully with some effort and care.
