Seasonal Maintenance Guides for Your Bluegrass

null

MOWING

Mow your bluegrass at the desired height; anywhere from 2.5 to 3.5 inches tall.
null

WATERING

Don’t overwater. Bluegrass needs about one inch of water a week considering rainfall.
null

FERTILIZATION

For optimal results, feed your lawn monthly during the fall season by applying the Lawnifi Spring Box liquid fertilizer program.
null

WEED CONTROL

Apply pre-emergent herbicide. This will cut down on summer weeds.
null

FUNGUS/INSECT

Apply fungicide if needed. If you have had a fungus or 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.
null

MOWING

When mowing, never remove more than 1/3 of the leaf blade. If you remove more than that, you will stress the grass and it may go brown for a short time. If you are returning from vacation, you may have to mow multiple times to get the grass back to the desired height. Wait about three to five days between each mowing.
null

WATERING

Do not overwater the grass. Bluegrass only needs about one inch of water weekly. Water for longer periods of time, less frequently, and in the early morning hours. Take rainfall into consideration.
null

FERTILIZATION

For optimal results, feed your lawn monthly during the fall season by applying the Lawnifi Summer Box liquid fertilizer program.
null

WEED CONTROL

Apply pre-emergent herbicide. This will cut down on summer weeds.
null

FUNGUS/INSECT

Treat with a broad-spectrum insecticide if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption.
null

MOWING

During the fall mowing will occur less often—keeping your bluegrass lightly higher will encourage deeper root growth for the winter.
null

WATERING

Water less as temperatures drop—too much water will lead to disease.
null

FERTILIZATION

For optimal results, feed your lawn monthly during the fall season by applying the Lawnifi Fall Box liquid fertilizer program.
null

WEED CONTROL

If you haven’t had past problems with winter weeds, you can forgo herbicide in the fall. If you do get winter weeds, apply a pre-emergent herbicide for prevention.
null

FUNGUS/INSECT

Apply fungicide. This will help the grass enter colder months in healthier condition. If you have had fungus before, you may need multiple applications in affected areas.

  • A thick, lush lawn is the best deterrent to weeds.

null

DISEASE CONTROL

  • Overly wet grass + shade = fungus problems.
  • Apply systemic fungicide to prevent fungus outbreaks.
  • Use multiple fungicide applications to treat affected areas.

null

INSECT CONTROL

  • Use a broad spectrum insecticide that controls chinch bugs
  • For a once-a-year treatment, July & August are good months
  • If using a granular insecticide, water in after applicatiom
  • Look for insect damage on grass blades and/ or roots

A WORD OF CAUTION FOR NEWLY SODDED LAWNS

A pre-emergent contains a chemical that prevents a weed from putting down roots. Because it is a root inhibitor, it can also negatively affect your new lawn, which is trying to establish itself by putting down roots.

If you successfully killed and removed your old lawn, including all the weeds in it, your newly sodded lawn should have relatively few weeds. It is suggested that you hand pick weeds out of your newly sodded lawn for the first season.
