At Earth Development, we use teams of local professionals with years of experience and great local reputations to provide the most comprehensive landscaping services in St Paul and throughout Minneapolis. We also aim to provide useful lawn care tips right here on our website, and today we’ll explore some summer lawn care tips broken down into steps for early, mid, and late summer.

Early Summer Lawn Care Tips

Your lawn care should be determined based on the kind of grass you have and the exact time of year. Let’s first explore late spring/early summer lawn care.

Fertilize Warm-Season Grasses

If you have warm-season grass, expect it to grow best in temperatures in the 70s (F). Any higher than that and your lawn will need additional care and potentially more shade to help avoid major damage.

In the early summer, May and June, be sure to apply fertilizer as early into the season as you can. This helps your lawn defend itself against high temperatures and makes it more drought resistant. Use too much, however, and you risk burning your lawn.

Spread your fertilizer evenly and cautiously, and use a specific summer grass fertilizer formula. Or, hire Earth Development for expert lawn fertilizer services.

People often ask “can you fertilize in the summer with cool-season grass?” and the answer is no. If you have cool-season grass, don’t fertilize the grass at all in the summer. Save that for the cool seasons.

Mow Your Lawn High

Remember to mow your lawn high in the early summer, too. The idea here is to encourage stronger root growth in your grass and to allow it to tolerate the heat more easily. When your grass is taller, it creates more shade on the soil. It protects the grass from the sun but also prevents weeds from germinating quite as easily.

Take a look at a lawn mowed too short in the summer, and you’ll probably notice that it looks unhealthy and weeds poke through the blades of grass more often.

For warm-season grasses, keep it between two and three inches tall. For cool-season grasses, try and keep it between three and four inches. Never cut more than one-third of your grass blade every time you mow.

Integrate Pest Control

Summer is the time when pests come out, and they can wreak havoc with your lawn. Whether they’re June bugs, beetles, grubs, or even European chafers, you can expect these pests to eat your grass and weaken its resilience to drought and high heat.

Use high-quality pesticides designed to kill bugs and pests without hurting your grass and apply them in the late spring or early summer.

Control Weeds

Early summer is also the perfect time for weed control. At this time of the year, you can more effectively kill weeds before they have a chance to grow, bloom, and then spread their seeds. It protects you this summer and even next summer because you are preventing the problem before it begins.

Many herbicides are designed to target weeds and not grass…but it’s not a perfect science. Use too much and you can still cause harm to your lawn, which is why we advise Minnesota businesses to entrust this process with our teams of local experts.

Mid-Summer Lawn Care Tips

Once you enter mid-summer, your lawn care should change slightly. There are two important tips to remember when it comes to mid-summer lawn care.

Water Your Lawn Properly

Once you reach mid-summer, the temperatures start to rise rapidly. This is when you must water your lawn properly. Overwatering can be just as bad as underwatering, and when the temperatures are high your grass can quickly wilt and die.

Be sure to water your lawn once or twice every week, and make sure that the water penetrates four to six inches. A good way to know that the water is penetrating the soil deeply enough is to insert a screwdriver or similar tool into the soil and see how resistant you feel. If it goes in too easily, it means you are overwatering. If you feel too much resistance, you need to water more. Make sure that you can push the screwdriver into the ground with some resistance, but not too much.  

Fertilize Your Grass

Lawns sometimes need mid-summer feeding, but this shouldn’t happen too frequently. Warm-season grasses are more likely to need this extra boost, but remember what we said about too much fertilizer burning your grass. Ask your local garden center or garden supplies company for the best mid-summer fertilizer and apply sparingly if necessary.

Late Summer Lawn Care Tips

Once you enter late summer, your lawn maintenance should be undertaken with next summer in mind. Here are some of our top late summer lawn care tips.

Aerate Your Lawn

Around August and September time, you should consider aerating your lawn. It’s not necessary, but it can be helpful. This is a process that involves pulling up “cores” from the soil or poking many long holes into the ground to break up any soil that has become compacted. It also makes it easier for air, water, and nutrients to penetrate more deeply into the soil.

This commonly overlooked late summer lawn care tip can be done with special aerating tools that make the job quicker and easier, or with garden forks and spikes.

Overseed Your Lawn If Needed

Overseeding in summer can have an amazing impact on your lawns’ growth next year, too. This helps fill out a lawn that has become patchy through the summer months – and you may even see some growth before the season ends. By applying additional seed across your lawn, you’ll have a healthier, more resilient, and greener turf.

Dethatch Your Grass  

Finally, don’t forget to dethatch your grass! This is a process whereby dead leaves and other organic matter are raked from the grass, leaving behind fresh soil and your lawn. It removes an organic barrier between the soil and the air, making it easier to apply nutrients and water.

Knowing when to dethatch a lawn is important. When we say to dethatch in the late summer (August and September) we’re talking about cool-season grasses. For warm-season grasses, dethatch the lawn during early summer – and never dethatch your lawn when it is stressed or dormant. That means no dethatching in the mid-summer or the middle of winter!
