The pot should be kept in a warm and moist environment with adequate light and humidity.
Air Layering Propagation
Air layering is another propagation method that can be used for Pelea parvifolia. The stem should be selected, and a notch should be created about an inch below a leaf node. A rooting hormone should be applied to the notch, and the area should be wrapped with moist sphagnum moss. The moss should be kept moist and covered with a plastic bag. After a few months, roots should develop, and the stem with roots can be separated from the mother plant and planted in a well-drained potting mix.
