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.
For optimal results, feed your lawn monthly during the summer season by applying the Lawnifi Summer Box liquid fertilizer program.
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.
Check for and control white grubs in July and August. Treat with an insecticide if needed.
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.
