Most lawns need 1-1.5 inches of water per week during the growing season, but this varies by grass type, season, and soil conditions. Cool-season grasses need more water in summer, while warm-season grasses need more during their peak growing season. Our calculator adjusts for these factors automatically.
Early morning (6-8 AM) is ideal because temperatures are cool, winds are calm, and evaporation is minimal. Avoid watering in the evening as this can promote disease, and avoid midday watering when evaporation rates are highest.
Signs of overwatering include soggy soil, fungal growth, and yellowing grass. Signs of underwatering include wilting, grayish-blue color, and footprints that remain visible. Use a screwdriver test - it should penetrate easily to 6 inches in well-watered soil.
Sandy soil drains quickly and needs more frequent watering, clay soil holds water longer and needs less frequent watering, and loamy soil provides the ideal balance. Our calculator adjusts your schedule based on your soil type to prevent over or under-watering.
During restrictions, prioritize deep, infrequent watering over light, frequent applications. Water early morning to maximize efficiency, focus on established lawns over new plantings, and consider allowing cool-season grasses to go dormant during extreme drought.
Use a rain gauge to track natural precipitation, install a smart irrigation controller, check for and repair leaks regularly, use mulch in landscape beds, choose drought-tolerant grass varieties, and mow at the proper height to encourage deeper roots.
Sprinkler systems provide even coverage but have moderate efficiency. Soaker hoses and drip irrigation are highly efficient but require more planning. Oscillating and rotary sprinklers are portable but less efficient. Our calculator adjusts timing based on your system's efficiency and application rate.
Inspect your system monthly during the growing season. Check for clogged or misaligned heads, broken pipes, and coverage uniformity. Run a test cycle and adjust heads to ensure even coverage. Replace worn nozzles and clean filters regularly for optimal performance.
Watering needs change significantly with seasons. Our calculator provides seasonal adjustments - you'll need more water in summer, less in spring and fall, and minimal water in winter (especially for warm-season grasses). Recalculate your schedule each season for best results.
Simply recalculate your schedule whenever you make changes to your lawn size, irrigation system, or if you notice your current schedule isn't working well. Our calculator will provide updated recommendations based on your new conditions.
