Q: How far out from my twenty-foot tall Leyland cypresses should I set my hose to water them?

A: The majority of the water and nutrient absorbing roots are five to fifteen feet away from the trunk. The easiest way to water is with a soaker hose. Run a loop around each tree, ten feet away. You’ll need approximately sixty feet of hose per tree. Hoses deliver one gallon per foot per hour. Use a water timer valve to water the trees for an hour each week in times of drought and hot weather.
