Lawn: Aim for approximately 1 to 1.5 inches of water per week, including rainfall. If you use a sprinkler system, it usually takes about 30 minutes to 1 hour of watering per session, depending on your sprinkler’s output and coverage. Watering deeply and less frequently is better than shallow and frequent watering.
Garden Plants: The water needs of garden plants vary, but a general rule is to provide about 1 inch of water per week through irrigation or rainfall. You may need to adjust this depending on the specific plants and weather conditions.
Trees and Shrubs: Mature trees and shrubs usually have deeper root systems and can withstand longer periods between watering. During dry spells, water deeply around the root zone, providing about 1 to 2 inches of water per application.
