Question: How much water should I give my shrubs and trees?
Answer: Your trees and shrubs need watering, just like everything else growing in your yard, especially in periods of little rain. Watering cools them off in hot weather and helps the plants absorb nutrients from the soil, as well as make their own food. Don’t get overzealous, however. Wait for signs of water stress, including wilting and loss of leaves. Here’s a rule of thumb for watering: Give your trees an inch of water every two weeks if you’ve had less than an inch of rain. Try to saturate the soil all at once, so the water goes deep. To monitor your watering, use a sprinkler and place an empty tuna can nearby. When the can is full of water, empty it and then fill again. Two fills will ensure adequate soil saturation. Water in the early morning or late evening to avoid quick evaporation.
