JULY: Maintaining the Spring Green 

If spring lawn care is about getting your lawn healthy and 

green, summer lawn care is about KEEPING it healthy while 

temperatures soar and rainfall becomes a fleeting memory. 

It’s also about maintaining a lawn that can withstand all the 

barbecues, games, parties, and running feet that summer has 

to offer. Here are some tips for keeping your lawn in shape over those long, hot days of summer. 

About Summer Lawns 

After the spring growing season, summer brings quite a bit of stress to lawn grasses. Not only are the heat and drought damaging, but we aren’t as forgiving in the summer as we are in the winter. We want our lawns lush and green for outdoor activities, and we try to fight nature by continuing to fertilize, water, and coax new growth out of our lawns no matter what the weather. However, by understanding and respecting the seasonal changes of turf grasses, you can take steps to care gently for your lawn as the mercury rises.

• Cool-season grasses (such as fescue, bluegrass, and rye) grow best when temperatures are in the 60s F. 
• Warm-season grasses (including Zoysia, St. Augustine, Centipede, and Bermuda) like temperatures in the 70s. 

Once temperatures get into the 80's and above, lawns will begin to struggle a little, with cool-season grasses having the hardest time. Growth will slow, color may fade, and lawns will show signs of wear and tear as they are less able to recover from stress and traffic. Some cool-season lawns will even go dormant in the summer, looking brown and brittle until early fall. 

Water Wisely

Lawns need at least one inch of water per week, and more when the heat is severe. Use a rain gauge or straight-sided can to keep track of the amount of water received from rainfall and irrigation.

• Water deeply and less frequently to encourage drought-tolerant roots.
• Water early in the day to reduce evaporation and fungal growth.
• Either water your lawn regularly and deeply, or don’t water at all. Don’t let your lawn go brown and dormant, then try to “water it back to life.” If your lawn goes dormant in summer, it should stay that
• way until fall – don’t worry, it should recover once the weather changes.
• Small tuna cans make a good temporary water gauge.

Mowing Tips

• Raise your mower blade in the summer. Taller grass is more drought-tolerant, grows deeper roots, and helps shade the earth to prevent weed seeds from germinating. Cool-season grasses should be mowed at 3”- 4” during the summer, or as high as your blade will go, while warm-season grasses should be mowed at 2”- 3”.
• Mulching grass clippings helps keep moisture levels steady.
• Mow regularly, to prevent cutting more than 1/3 of the grass blade at a time. This keeps your grass healthier and prevents the clippings from smothering the grass.
• Keep mower blades sharp. Make sure your mower is cutting your grass, not tearing it, to minimize stress during hot temperatures.

Don’t Over Fertilize
If your lawn is looking straggly in midsummer, resist the urge to fertilize. In fact, it’s best to stop
fertilizing about 30 days before your area’s summer temperatures arrive. Applying extra fertilizer in the heat of summer can burn your lawn and create a flush of tender growth that will struggle in the hot summer weather. Never fertilize dormant lawns – wait until they green up in the fall. 

Control Weeds
Summer is the season to get those growing weeds removed before they bloom and disperse seed for next year. Targeted postemergent herbicides are designed to kill broadleaf weeds without harming turf grass, but they must be applied when temperatures will be below 85° F for a few days. Keep in mind that during the heat of summer, ANY product can be damaging to already-stressed lawn grasses, so use sparingly or hand-pull weeds instead.

High-Traffic Areas
By summer, many lawns begin to show signs of wear, especially in a few popular pathways. Consider installing stepping
stones to minimize damage to your grass, and try to minimize traffic on dormant, brittle lawns. If you’re getting plenty of
rainfall and your lawn is actively growing, you can apply a bit of fertilizer to these areas to help the blades recover faster.

Insects and Diseases

• Dormant or drought-stressed summer lawns can be more susceptible to insect infestations, such as chinch bugs, cutworms, armyworms, sod webworms, fire ants, fleas and mosquitoes. Minor infestations often take care of themselves, but severe problems may require attention.
• Summer is also the time for fungal diseases, such as powdery mildew and brown patch.
• Apply fungicide if needed, and avoid watering in the evening to keep nighttime moisture at a minimum.
• Grubs will begin hatching in your lawn over the summer. If grubs typically cause problems in your lawn, you can begin applying grub control around midsummer.

In Conclusion
It's best to hold off until later in the season for most other lawn care practices, including fertilizing, seeding, thatch control, and applying weed killers. The period from late August  through early September is ideal for many of these practices. For now, help your lawn by proper mowing, watering, and keeping foot and vehicle traffic off the grass as much as possible during the heat of the summer months.
