Bluegrass Maintenance

Care Guide

Season-by-season lawn care

From the natural turfgrass experts — breeding, licensing, and lawn care guidance.

Seasonal Care

Spring Maintenance

Mowing

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.

Watering

Don’t overwater. Bluegrass 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 and goosegrass 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 bluegrass. If, however, you notice disease in your bluegrass, apply a systemic fungicide.

Seasonal Care

Summer Maintenance

Mowing

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.

Watering

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.

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

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.

Seasonal Care

Fall Maintenance

Mowing

Mow your bluegrass at a height of 2.5–3.5 inches in height during the fall.

Watering

Bluegrass 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 chickweedhenbitPoa annua or purple deadnettle. Apply post-emergent herbicides only when weeds are present.

Insect Control

Check for and control any white grubssod webworms or fall armyworms. Treat with an insecticide if needed.

Fungus Control

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.
