Seasonal Guides for Your Fescue Maintenance
SPRING
Mowing
Don’t make the mistake of mowing your fescue lawn too short. Keep your lawn between 2.5–3.5 inches in height with a rotary mower that has a sharpened blade. Never remove more than ⅓ of the leaf blade.
Watering
Don’t overwater. Fescue needs about 1-inch of water a week from natural rainfall or irrigation.
Fertilization
For optimal results, feed your lawn during the spring season by applying Lawnifi Foundation, a granular fertilizer, or the Lawnifi Spring Fertilizer Box.
Weed Control
Apply a pre-emergent herbicide when soil temperatures reach 55 degrees Fahrenheit. This will prevent summer annual weeds like crabgrass, goosegrass and foxtail from plaguing your lawn and garden.
Insect Control
Apply a broad-spectrum insecticide to prevent spring insects from appearing or to control any current spring insects like white grubs. White grubs may be active at this time.
Fungus Control
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.
SUMMER
Mowing
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.
Watering
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.
Fertilization
For optimal results, feed your lawn monthly during the summer season by applying the Lawnifi Summer Box liquid fertilizer program.
Weed Control
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.
Insect Control
Check for and control white grubs in July and August. Treat with an insecticide if needed.
Fungus Control
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.
FALL
Mowing
Mow your fescue at a height of 2.5–3.5 inches in height during the fall.
Watering
Fescue requires about 1–1.25 inches of water every week including rainfall and supplemental irrigation. Don’t overwater.
Fertilization
For optimal results, feed your lawn monthly during the fall season by applying the Lawnifi’s Fall Fertilizer Box or apply Lawnifi Foundation once every three months.
Weed Control
Apply pre-emergent herbicides to control winter annual and perennial weeds like chickweed, henbit, Poa annua or purple deadnettle. Apply post-emergent herbicides only when weeds are present.
Insect Control
Check for and control any white grubs, fall armyworms or sod webworms. Treat with an insecticide if needed.
Fungus Control
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.
