How Much Water Do Apple Trees Need?
Apple tree water requirements depend on rainfall. In general, for an established tree, you won’t need to water it unless you are not getting much rain or there is a particularly dry spell or even drought. About an inch (2.5 cm.) or so of rainfall every week to ten days is adequate for most apple trees. Trees in their first growing season may need a little more than this.
How to Water an Apple Tree
When you do need to water your tree, it is important to do so without creating standing water and soggy roots. This can be as damaging as drought conditions for your tree. Too much water depletes oxygen from the soil, prevents the roots from absorbing necessary minerals, and makes a tree susceptible to rot and infections. Ideal apple tree irrigation involves giving the roots a deep soaking. Let a garden hose trickle around the base of the tree for an extended period of time. This will give the soil time to soak up the water and minimize runoff. A soaker hose can do multiple trees at one time. Each time you water, make sure the ground around the tree and roots gets fully soaked. Knowing how much water to give your apple tree will depend on factors unique to your climate, weather, and soil. If you see standing water, you may be overwatering. If the weather is unusually hot or dry, you may need to increase watering for that period of time. Waterlogged roots are always worse than dry roots, so always err on the side of caution when watering apple trees.
