How Often Should You Water Fescue Grass? A Simple Guide for NC Lawns
Fescue grass is a popular choice for lawns in North Carolina—especially in areas like Holly Springs and Cary—thanks to its ability to stay green most of the year. But if you want a healthy, lush lawn, watering fescue properly is key.
Whether you're maintaining tall fescue or a fescue blend, here's everything you need to know about how often to water it, and how to adjust for the seasons.
How Often Should You Water Fescue?
In general, fescue needs about 1 to 1.25 inches of water per week, including rainfall. That can be split into 2–3 deep waterings per week, rather than light daily watering.
Why deep watering?
Deep watering encourages the grass roots to grow deeper, making your lawn more drought-tolerant and resilient.
Seasonal Watering Guide
Spring & Fall (Peak Growing Season)
Water 2–3 times per week
Aim for 1 inch total (including rain)
Water in the early morning to prevent disease
These seasons are when fescue thrives. Natural rainfall often helps, but you may still need to supplement during dry spells.
Summer (Dormant Period)
Fescue may go dormant in hot weather, especially in NC heat
If maintaining a green lawn: Water 3x per week, up to 1.25 inches total
If allowing dormancy: Water occasionally (once every 2–3 weeks) to keep the crowns alive
Fescue isn’t a warm-season grass, so you’ll notice browning in summer unless you actively water and care for it.
Winter
Watering is rarely needed unless it’s unusually dry and warm
If watering, do it during the warmest part of the day
Watering Tips
Use a rain gauge or tuna can to measure how much water your lawn is getting.
Avoid watering in the evening—this can lead to fungus and disease.
Make sure your sprinkler system is covering the lawn evenly, especially in large or oddly shaped yards.
Pro Tip
If your fescue lawn starts to look dull or the blades curl, it’s a sign it needs water. But if you step on it and the grass doesn’t bounce back, it’s definitely time to water.
