Watering correctly is one of the biggest factors in keeping a lawn green through Southern Utah’s hot, dry summers. Water too little and you get brown, stressed grass; water too much and you waste money and invite disease. Here is a practical guide to watering your lawn in the St. George area.
How Much Water Does a Lawn Need Here?
Most lawns in the St. George area need roughly 1.5 to 2 inches of water per week during peak summer, and less in spring and fall. Because our summers are hot and dry, lawns here often need more water than the national average, but the goal is always deep, less frequent watering rather than short daily sprinkles, which encourages stronger roots.
Best Time of Day to Water
Water early in the morning, ideally between 4 a.m. and 8 a.m. This reduces evaporation, lets the grass dry during the day, and helps prevent fungal problems. Avoid watering in the heat of the afternoon, when much of the water evaporates before it reaches the roots.
Signs You Are Watering Wrong
- Footprints that stay visible in the grass, a sign of under-watering
- Brown or dry patches even when the system runs
- Soggy spots, mushrooms, or runoff, a sign of over-watering
- Sudden jumps in your water bill
Adjust With the Seasons
Your watering schedule should change through the year. Increase watering through June, July, and August, then scale back in spring and fall as temperatures drop. Many local watering problems come from running a hot-summer schedule into the cooler months.
