If it just feels cool because of the moisture, I water. Forcing an established plant to abandon lazy ways and develop roots takes time, they warned. The changeover from frequent to infrequent watering must be gradual. Otherwise, plants develop homeowner-caused drought stress. Plus, infrequent watering must be deep.
Moist soil allows it to pass easily.
Dry soil stops it in place. A The west may be dry. The hard pan traps rainfall. For days after a storm, you can dig down and reach water 4 to 5 inches below the soil surface, as the moisture tries to drain away. In a drought, however, this same soil profile literally hangs shallow-rooted plants out to dry.
