Choose a portion of the stem you wish to root with healthy foliage at the tip. Remove the leaves on the lower section of the stem. Leave about 3 inches of bare stem for smaller plants and allow up to 10 inches for larger plants or shrubs.
Take a pair of sharp loppers or clippers and make a clean, angled cut. Make the cut at the bottom of the bare stem section. Clean the cutting tool with disinfectant after you have clipped all the tips you wish to root.
Place the tip and stem section in a propagation medium with a mixture of moistened peat moss, perlite, vermiculite and sand. Apply a heating cable to the bottom of the pot. Set the temperature at 75 degrees. Keep the soil moist.
Place the stem in a glass container with clean water for another rooting option. Provide plenty of diffused light, but no direct sunlight. Store in a well-ventilated area during the rooting process.
