Create a personalized watering schedule for your lawn based on grass type, soil conditions, and irrigation system. Get precise timing, water amounts, and cost estimates.
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.
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.
