The most commonly used method of asexual propagation for Angraecum Rhodostictum Kraenzl. is stem cuttings.
Stem cuttings are taken from healthy, mature plants during their growth phase. Cuttings are taken early in the morning when the plants' water content is highest. The cuttings are usually 5-10cm long, and they should be taken from the upper part of the stem, just below a node. The cutting is then placed in a rooting hormone to stimulate root growth.
After treating with rooting hormone, the cutting is planted in a medium that provides a good balance of moisture and air. The ideal medium for Angraecum Rhodostictum Kraenzl. is a mixture of sphagnum moss and vermiculite in equal proportions. The cutting should be kept in a warm and humid environment for several weeks to encourage root development.
Once the cutting has developed strong roots, it should be transplanted into a potting mix and kept in a warm, humid environment with bright, filtered light. Gradually accustom the plant to brighter light as it matures
