The answer to 'irrigation system schedule' is that the optimal irrigation schedule for your landscaping depends on several factors, including your climate, soil type, and the specific plants in your yard. As a general guideline, most lawns and gardens need about 1-2 inches of water per week, either from rainfall or irrigation. The best time to water is early morning or late evening to minimize evaporation. You'll also want to adjust your schedule seasonally, watering more in hot, dry months and less in cooler, wetter periods.
It's important to monitor your plants and soil moisture and make adjustments as needed. Overwatering can be just as harmful as underwatering, so pay attention to signs of stress in your landscaping. If you're unsure about the right schedule for your property, it's a good idea to consult a local landscaping professional who can assess your specific needs.
