|You suggested my boulevard cypress pom is turning brown due to water stress. Does that mean too much water or not enough?
|I could be either. Droughty conditions can cause browning foliage, but overly wet conditions caused by soil that does not drain well or too much water from the hose can actually suffocate the roots and kill the vascular system. In general, landscape trees and shrubs need about an inch of water per week which can be supplied by rainfall or water from the hose. If you think you may have overwatered, dig down into the root system to see if it is mushy or slimy. Break a few of the smaller roots. Healthy roots will be creamy white inside; dead roots will be brown, black or rusty colored. Hope this sheds some light on the subject!|
