To propagate a tree cutting, remove the leaves from the bottom one-third of the cutting, and remove any flowers or buds. Dip the cutting in rooting compound before inserting the bottom one-third to one-half of the cutting in sterile, well-draining growing medium, such as a mixture of peat and perlite. Cover the cutting with plastic wrap, and place the container in a warm location with indirect sunlight. Water the cutting as needed to maintain moist growing medium.
To encourage rooting, take a 4- to 6-inch cutting of new growth from the upper portion of a young, healthy plant. Take the cutting in the early morning, and store the cutting in a cooler or inside a dark-colored plastic bag with several damp paper towels. Mist the cuttings with water on a regular basis.
When propagating coniferous trees, do so in the late autumn or early winter to promote successful growth, and propagate other species after new growth appears.
When treating the cutting with rooting compound, place a small amount of the compound in a container, and drip the cut end of the cutting into the compound. Discard any remaining compound to prevent transmitting diseases among cuttings. Allow the cutting ample time to develop a strong root system before transplanting.
