Seasonal Guides for Your Bluegrass Maintenance
Don’t make the mistake of mowing your bluegrass 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.
Don’t overwater. Bluegrass needs about 1-inch of water a week from natural rainfall or irrigation.
For optimal results, feed your lawn during the spring season by applying Lawnifi Foundation, a granular fertilizer, or the Lawnifi Spring Fertilizer Box.
Apply a pre-emergent herbicide when soil temperatures reach 55 degrees Fahrenheit. This will prevent summer annual weeds like crabgrass and goosegrass from plaguing your lawn and garden.
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.
Unlike warm season turfgrasses, there’s typically no real reason to make fungicide applications in the spring for bluegrass. If, however, you notice disease in your bluegrass, apply a systemic fungicide.
When mowing during the summer, bluegrass 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. Bluegrass 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.
Bluegrass 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 2:00–8:00AM. Apply a fungicide like Heritage G during severe brown patch outbreaks.
Mow your bluegrass at a height of 2.5–3.5 inches in height during the fall.
Bluegrass requires about 1–1.25 inches of water every week including rainfall and supplemental irrigation. Don’t overwater.
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.
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.
Check for and control any white grubs, sod webworms or fall armyworms. Treat with an insecticide if needed.
Apply fungicide if needed. If you have had a disease in your bluegrass in the past or have quite a bit of shade in the yard, apply a systemic fungicide to prevent future outbreaks.
