Seasonal Guides for Your Fescue Maintenance
Don’t overwater. Fescue needs about 1-inch of water a week from natural rainfall or irrigation.
Unlike warm season turfgrasses, there’s typically no real reason to make fungicide applications in the spring for fescue. If, however, you notice disease in your fescue, apply a systemic fungicide.
When mowing during the summer, fescue usually performs best at a height of 2.5–3.5 inches. Never remove more than 1/3 of the leaf blade at a time.
Do not overwater the grass. Fescue only needs about 1-inch of water weekly. Water for longer periods of time, less frequently and in the early morning hours.
It is not recommended that you apply an herbicide at this time because when temperatures exceed 85 degrees Fahrenheit, the herbicide will damage the grass.
Fescue is highly susceptible to brown patch disease, which appears as irregularly shaped patches of dead or dying turf. Do not apply nitrogen fertilizer when the disease is active, keep the mowing height above 3-inches and water between 2:00–8:00 a.m. Apply a fungicide like Heritage G during severe brown patch outbreaks.
Mow your fescue at a height of 2.5–3.5 inches in height during the fall.
Fescue requires about 1–1.25 inches of water every week including rainfall and supplemental irrigation. Don’t overwater.
Apply fungicide if needed. If you have had a disease in your fescue in the past or have quite a bit of shade in the yard, apply a systemic fungicide to prevent future outbreaks.
