How to Fix Thin, Patchy Lawns in Minnesota
Frustrated by thinning grass under your trees or a patchy section on your lawn? A thin, patchy area in your Minnesota lawn can be caused by a variety of reasons, including shade, poor soil quality, and soil compaction. Our lawn care experts created these tips on how to fix patchy grass to help you identify the source of your patchy lawn–knowing the problem is the MOST important part of finding a solution
What causes patchy grass & thinning lawns?
Patchy, thin grass is usually an indicator of a bigger problem. It may be tempting to simply add fertilizer or spread grass seeds. Unfortunately, trying the wrong solution can waste time and money and could potentially make things worse. Understanding what’s causing the problem is the key to successfully overcoming it.
Below are the most common causes for thinning grass in Minnesota lawns and how to fix them
Compacted or hard soil
If your soil is too hard (compacted), it creates a hostile environment for growing grass. When soil is packed down, it prevents roots from getting the air, water, and nutrients they need to grow, resulting in thin grass. Compacted or hard soil can be remedied through lawn aeration and soil amendments.
Improper mowing or watering
Good lawn care practices like proper mowing and lawn watering can go a long way toward preventing thin patchy lawns and bringing them back to health.
Not enough fertilizer
Lawns need soil with the proper pH and a balanced composition of nitrogen, phosphorus, and potassium to stay in top condition. You can learn more about fertilizer options and how to apply it yourself in our Homeowner’s Guide to Lawn Fertilization. If you’re in our Twin Cities service area, we offer a variety of custom-tailored fertilizer packages to fix your patchy lawn.
A disease or insect problem
Lawn diseases, such as powdery mildew, or insects like Japanese Beetles and grubs, can create thin, patchy grass. The first step is to properly diagnose what insect or disease may be impacting your lawn. From there, you can apply a treatment–or seek professional assistance–to correct the underlying disease or insect issue.
Too much shade
Shade problems can also cause or contribute to thinning grass under trees or in random lawn patches. Even grass seeds that have been specially cultivated for use in shaded areas can struggle without enough sunlight, resulting in thin grass growth, straggly grass, and bare patches. The best way to address a densely shaded area is to consider mulch or a different ground cover.
How does soil quality impact thin, patchy lawns?
Our experts recommend soil testing when there is a difficult problem to diagnose or your lawn has not responded to other treatments. These tests provide a wealth of information about your soil, including nutrient levels, pH, and other conditions that impact your lawn’s heath. We also suggest current clients have regular soil tests performed every three or four years if they have challenging conditions on their property.
