If you have ash trees that you are protecting from emerald ash borer with insecticide treatments, be sure to water them during dry spells. Water-stressed trees are more susceptible to the borers. Keeping them watered will make them less attractive to emerald ash borer, and will help them recover faster from borer injury.
