Propagation Methods for Pelea puauluensis St. John Plant
Propagation of Pelea puauluensis St. John plant is usually done through cuttings and seeds. Both methods require favorable environmental conditions for the plant's growth and development.
Cuttings
Cuttings are usually taken in the spring or early summer when new growth is present. Select a healthy stem and make a clean cut just below a node with a sharp, sterile knife. Remove the lower leaves from the cutting, leaving only the top 2-3 leaves. Dip the cut end of the stem in rooting hormone and place it in a well-draining potting mix. Water the soil to settle it around the cutting and then cover it with a plastic bag or plastic wrap to retain moisture. Place it in bright, indirect light and keep the soil moist until roots have formed, which can take several weeks to a few months depending on the conditions.
Seeds
Seeds collected from the Pelea puauluensis St. John plant usually require a period of stratification or chilling to germinate. Soak the seeds in water for 24 hours, then place them in a plastic bag with a moistened paper towel and place it in the refrigerator for 4-8 weeks. After this chilling period, sow the seeds in a well-draining potting mix and cover lightly. Keep the soil moist and place the pot in a warm, bright place. Germination can take several weeks to a few months depending on the conditions. Once the seedlings have grown big enough to handle, they can be potted into their individual containers.
