Mow as needed, frequency of mowing should decrease due to heat stress on cool season grasses. Irrigation will be required if turf is to remain green throughout the season. If restrictions on irrigation are enforced, due to extended drought periods, one half inch of water per month is all that is required by grasses to keep the crown from dying.
Trees and Shrubs:
Continue to scout for weed, insect and disease problems. Only treat problems that are causing significant damage. During hot periods aphids, scale insects, and mites populate rapidly. The use of pheromone traps could aid in early detection of insects. Remember that the presence of insects does not necessarily indicate a need to spray. Provide water for newly planted trees and shrubs as needed. Established plantings should be watered if season has been dry. Use at least one inch of water per week in one application. Applications of an additional one half of pre-emergence herbicide in planting beds will extend weed control. Weed beds as needed.
Trees that have lost considerable foliage but retain at lease one third of their foliage past the first of July are usually able to recover for the following season.
