Use hand pruners and cut at a 45° angle at least 6-8 inches long off at right below a leaf node. Remove the leaves on the bottom half of the branch. Then cut the remaining leaves in half to still promote photosynthesis but not take excess energy away from the rooting system. Use a sterilized knife or box cutter to scrape the stem down to the green inner growth, breaking through the outer layer. Dip in root hormone (mixed in water at a paste consistency) and place in damp, well-draining, moist potting soil mix and tamp down around the stem to secure it. Use a container that has drainage and is deep enough for the roots to grow. Plant at least 1-2 inches down into the soil. Mist inside a clear plastic bag to create moisture and humidity. Place the bag over the top of the plantings and let it set over the planter. There is no need to tie off the bag but allow a little airflow under and into the planting pot. Set it in bright, indirect sunlight while they are rooting. Check the moisture and humidity each day and add misting to keep the soil moist while the roots establish.
After 6-8 weeks, roots will begin to form. You can tug onto the stem to ensure the roots are establishing. When temperatures are warm outside, transplant into the garden for years of enjoyment!
