If you have a plum tree, you should get about an inch of water from rainfall or irrigation every week, otherwise you may find that the blossoms drop and/or the fruit does not mature.

During dry periods of the year, water the soil to the point of soaking it up several inches deep once per week if rainfall is not sufficient.

There can be significant reduction in plum production if rainy or cloudy weather or exceptionally strong winds prevail during the bloom period. This is because bees have minimal opportunities to pollinate, and this can slow the blooming process.

A great deal of plum trees are self-incompatible, which means that they are unable to produce fruit of their own. In order to start producing fruit they need another variety of plum tree.

Even the plum varieties considered self fertile tend to produce more fruit For a plum tree to produce at its best, there must be another variety of plum tree blooming at the same time within 50 feet or less, and some willing pollinators to do the transferring.

If the plum tree does not receive the chilling hours it needs, then it may not be able to even bear fruit, or it may be forced to blossom too early, and the blossoms will get destroyed by frost.

It is recommended that Japanese plum varieties be chilled for 500 hours to 900 hours for the best quality. In Europe, plum varieties are usually grown in cool climates and require up to 700 hours of chilling, although there are varieties adapted to the warmth of the tropics.

Fruit trees should be fertilized with a balanced formula like 10-10-10 or a higher phosphorus fertilizer (the P in N-P-K) as phosphorus is the element that is most important for blooming and fruiting.
