Lawns can go dormant in a dry spell, but trees and shrubs remain active during growing season. We’re in the dry part of summer now, with moderate drought conditions when surface water level declines and plant growth can be stunted so please continue to water trees and shrubs.
When you water, wet the entire root area of the tree and soak the soil approximately 12 inches deep. A 6-to-8 foot tree uses about 2 1/2 to 3 gallons of water once a week.
Soaker hoses, trickle or drip systems can feed the root zone with minimum surface wetting and water waste. Alternatively, a berm around the tree or shrub base may be filled with water for slow infiltration and percolation into the root zone.
