The waxy plum can be propagated through several methods, including seed sowing, cuttings, grafting, and ramification. Each technique has its own advantages and is suitable for different growing conditions and goals.
1. **Sowing Method**
a. **Autumn Sowing**: After the fruit matures between July and August, it is harvested, and the seeds are extracted from the fruit. These seeds can be sown immediately. Within 10 days of planting, seedlings will begin to emerge. They can grow up to 20 cm in height within a few weeks.
b. **Spring Sowing**: This method is typically done between March and April, using seeds that were collected and stored the previous year. Before planting, the seeds should be soaked in warm water (30–40°C) for 12 hours to enhance germination. Then, they are planted in sandy loam soil. It usually takes 15 to 20 days for the seedlings to appear. With proper care, these plants can take 3 to 4 years before they start flowering.
2. **Ramet Method**
The ramet method is best performed when buds begin to sprout, usually between March and April. The plant selected for ramification should be at least 20–30 cm above the ground. Ideally, the previous year’s growth should have been pruned to allow the mother plant to store more nutrients. To perform this, soil around the base of the mother plant is carefully removed, and a portion of the plant is cut away with a knife, ensuring minimal damage to the root system.
3. **Grafting Method**
Grafting is commonly used to improve the quality and productivity of waxy plum trees. There are two main approaches: cutting and docking.
a. **Cutting**: This is usually done between March and April, when buds begin to swell. The scion should be taken from a healthy 2–3-year-old tree, selecting strong one-year-old branches. The scion is cut into 6–7 cm sections, leaving 1–2 pairs of buds. The cut surface is slightly angled, exposing a small amount of xylem. The rootstock, which is typically a 4–5-year-old seedling, is cut 3–6 cm above the ground, creating a split that is 4–5 cm long. The scion is then inserted into the rootstock, aligning the cambium layers, and secured with plastic tape. A small amount of wet mud is applied to the interface, and the area is covered with soil to keep it moist.
b. **Docking**: This method is best carried out between May 6 and May 21 each year. The rootstock is selected from a fine variety of Lamei, and a branch of similar thickness is chosen as the scion. Both the rootstock and scion are cut with 3–9 cm incisions, making sure not to damage the xylem. The incision on the rootstock should be no higher than 20 cm. The wounds are matched carefully, especially the cambium layers, and tied tightly with string. Wet mud is applied to the interface, and it is wrapped with plastic film to maintain moisture. The branches on the rootstock are lightly cut but not removed entirely, allowing them to continue supplying moisture and nutrients to the scion. After about 40 days, when new leaves and shoots appear on the scion, the lower part of the incision is cut, and all the branches and leaves above the root cut are removed, allowing the grafted plant to become independent.
