Maintain a good mowing and watering schedule to keep grass healthy. Leave grass clippings on the lawn.
Apply water soluble fertilizer or foliar feed to plants as needed - usually every 2-4 weeks.
Lightly prune small trees to improve air circulation and control white powdery mildew on leaves. Powdery mildew is not harmful, only unsightly.
