Planting a cutting of a plum tree requires care and attention to detail to make it successful. Hardwood plum cuttings are somewhat more difficult to root, but plum trees grow successfully from proper care of hardwood cuttings.
The size and health of the cutting must be adequate for a hardwood plum cutting to root. Cuttings should be several inches long and with no visible health problems, such as breaks, torn bark or fungal spots.
Rooting the Cutting
Hardwood cuttings grow best under a controlled environment for the first growing season. Dipping the end of the hardwood plum cutting into a rooting hormone helps encourage the cutting to put out healthy roots.
One of the most important factors of growing a hardwood plum cutting is keeping the cutting moist from the time it is taken until it is planted. Plum cuttings that dry out may not sprout roots.
