Plum trees are an ideal addition to any home or garden, for their delicious fruit harvest, easy maintenance and shade. Plum trees grow easily in most parts of the United States, but proper watering is key to their health.
Provide young or newly planted plum trees with generous water during any dry spells and immediately after planting. If your plum tree is growing against a wall or fence, then you will need to provide it with almost twice as much regular watering throughout the tree's life than a plum tree that isn't planted by one.
The tree needs deep watering every 7 to 10 days. Let regular rains provide the water for your tree if you live in a wet climate. If you aren't getting any rain, let a slow-running hose or root feeder (without fertilizer) soak the soil for 15 to 20 minutes at a time.
Observe your plum tree to make sure it is not getting too much water or too little. If the leaves curl up and turn brown, the tree needs water. If they grow yellow and start to drop, it has been watered too often.
Maintain your watering schedule into mid-October so that the tree goes into the winter with a good moisture supply.
