5 Tips for Summer Lawn Care in Minnesota

Home / Summer / 5 Tips for Summer Lawn Care in Minnesota

Summer heat can take a toll on your lawn.  If you mow too low, water too much or too little, or ignore early signs of pests, your grass could quickly become lackluster or even completely die in small or large patches. Keep your lawn looking its best all summer long by following these 5 summer care tips.

1. Mow at the right height.

In summer, adjust your mower height to leave grass taller. Taller grass shades soil, which reduces water evaporation, leads to deeper roots and prevents weed seeds from germinating. Ideal mowing height varies with grass type. Time mowings so you’re never removing more than one-third of the leaf surface at a time.

2.Water properly.

The most efficient time to water lawns is probably early in the morning hours from 4 to 8 a.m. Less water is lost to evaporation due to lower temperatures and less sunlight.

Midday watering, though good for the plants since it cools the plant temperatures and reduces heat stress, is not as efficient because some of the water evaporates before getting into the soil.

Watering in the evening should be avoided. If the grass plants go into the night-time hours wet, they will remain wet for extended periods of time. This may favor the growth and development of turfgrass diseases.

3. Treat for grubs.

Insecticides for grubs can be applied from May through mid-June, when recently overwintered grubs (larvae) start feeding. However, these grubs are large and may be difficult to kill. Starting in mid- June most grubs are in the pupal stage and insecticides are not effective. In early July adults emerge to feed on plants, mate, and then at night fly to grass to lay eggs. The best time to apply insecticides for grubs is from mid-July until early September. Granular applied insecticides distributed on soil with a spreader are usually the best insecticides

4. Clean up after your pooch.

The family dog can cause dead spots on a lawn. If you see dying grass due to your dog’s urination, flush the area with water to dilute the urine in soil. The best solution is to create a mulched or pebbled area and train your dog to use that area for bathroom breaks. Also, keep waste picked up and dispose of it properly.

5. Sharpen your mower blade.

A dull mower blade tears grass, creating ragged, brown edges that provide an opening for disease organisms. Sharpen your mower blade regularly. The rule of thumb is that a sharp blade lasts for 10 hours of mowing. Consider purchasing a second blade so you’ll always have a sharp blade at the ready.

  1. Thanks for mentioning to water during the morning. I didn’t realize watering at specific times could help your grass stay healthier. I want to take better care of my lawn this year, so I have been looking for some tips. These should help, I appreciate the post!

  2. It’s really interesting how you point out that the most efficient time to water lawns is early in the morning hours from 4 to 8 am. My mom really wants her lawn to look greener and better kept, because her neighbor’s yard always looks perfect. I think it would probably be helpful if she had a landscaping company come and help her get her yard taken care of.

  3. I wasn’t aware that the best time to water your lawn was between 4-8am. I’ll have to keep this in mind as I try and get my yard into good shape. My yard is struggling this summer but I don’t have a ton of time to take care of it myself. I’ll have to look into hiring a company to come and make sure my yard is well taken care of this summer.

    1. Yes, early morning is crucial to a healthy lawn because it gives your lawn the ability to soak up all the nutrients before the sun can steal the moisture away.

  4. My parents will be gone for a long time for vacation and they wanted to make sure that their lawn will be maintained. It was suggested here that it should be watered properly. Furthermore, it’s advisable to hire professionals for quality lawn care services.

  5. I really appreciate your tip to try and train your dog to go to the bathroom in the same place on your lawn so your lawn can be healthier. My wife and I have been thinking of getting a dog, and I take a lot of pride in my lawn. I will be sure to tell my wife that we should try and train our dog to go to the bathroom in the same place every time!

  6. Thanks for pointing out how applying insecticides in your lawn is best during July until early September since these grubs are more vulnerable during that time frame. I have three kids in my household, so I think applying these chemicals in our lawn myself can potentially put them at risk. A professional lawn care service will definitely do a much better job at getting rid of the grubs and maintaining my exterior with professional-quality care.a

  7. Thanks for the great tips. We see our customers cut their lawns so short (think golf course green) thinking they won’t need to mow as often. It leaves us with the most dull brown dehydrated lawns and often patches of dead burnt grass. It’s really hard to come back from that.

  8. Great tips which have far reaching impact. We get questions from clients thinking our concrete slabs affected their grass but turns out they cut it so short it pulls away from the slab leaving a gap that exposes the sod. Keeping the grass longer and cutting more often definitely solves this issue.

  9. I like your blog. It is interesting to read. As everyone know we have to take extra care of lawn care in summer. I will surely follow your tips and I will share you feedback.

  10. Some lawn care experts recommend fertilizing your lawn several times a year but recent studies report that cool-weather grasses are best fertilized during late fall. Warm weather grasses, on the other hand, must be fertilized during early spring as their growth peak during the summer.
