Yes, watering may be necessary in our dry summer months. The last few summers have been exceptionally hot and dry which have stressed many woody landscape plants. Even established trees & shrubs with more established root systems have been showing signs of drought stress. Many times, trees & shrubs that are near irrigated lawns or landscaped areas will handle drought stress better.

Check out page 13 & page 15 of the pdf of this OSU Extension publication for helpful tips. While this guide is gear toward care of newly planted trees, the tips for mulching (page 13) and the diagram showing where to water to target the root zone (page 15) will be helpful.
