Root-promoting substances increase the percentage of cuttings that root, shorten the period needed for rooting, and increase the number of roots per cutting. Most products are in powder form. To avoid brushing off the powder when inserting the cuttings, make holes in the rooting medium with your finger or a pencil. Insert the cuttings approximately 2 inches deep into the rooting medium. After all the cuttings are inserted, carefully water the medium and let it drain.
Water is critical to the survival of the cuttings.
A cutting has no root system to absorb water, yet continues to lose water through its leaves. The cutting will wilt and die if it loses a large quantity of water. Water loss can be reduced by placing a glass jar over the cuttings or by inserting several stakes just inside the wall of the container and then placing a clear plastic bag over the cuttings and container. Once covered, place the cuttings in bright light, but not direct sunlight. Inspect the cuttings daily.
