Plum trees require consistent moisture, particularly during flowering, fruit set, and dry periods. Deep watering once or twice a week is generally sufficient, ensuring the soil is moist to a depth of 30-45 cm.

Avoid waterlogging, which can lead to root rot and other issues. Young trees need more frequent watering to establish their root system effectively.

Prune plum trees annually in late winter or early spring while dormant to maintain shape, remove dead, diseased, or crossing wood, and encourage fruit production.

Open the canopy to improve air circulation and light penetration. Thin out overcrowded branches and remove any suckers from the base. Light summer pruning can manage growth.

Plum trees are commonly propagated by grafting desired cultivars onto suitable rootstocks for disease resistance and size control.

They can also be propagated by semi-hardwood cuttings taken in summer, treated with rooting hormone, and rooted in a moist, well-drained medium. Seed propagation is possible but does not guarantee true-to-type offspring.

Repotting is not applicable for mature plum trees grown in the ground, as they are permanent landscape features.

For young trees grown in containers, repot every 2-3 years into a slightly larger pot with fresh potting mix. This is typically done in late winter or early spring before active growth resumes. Ensure good drainage.
