Spring Lawn Care Tips for Illinois Lawns

As the weather warms up and the snow melts, it’s time to start thinking about your lawn and preparing it for spring. If you live in Illinois, there are a few key things you can do to ensure that your lawn stays healthy and looks its best throughout the season.

One of the most important things you can do for your Illinois lawn in the spring is to dethatch it. Thatch is a layer of dead grass, roots, and other organic matter that builds up on the surface of your lawn over time. If left unchecked, thatch can prevent water, nutrients, and air from reaching the roots of your grass, leading to a weak and unhealthy lawn.

A good telltale to know if you need to dethatch is if your lawn feels bouncy on top of the lawn when you walk on it. Having some dead organic matter is not bad, but when it gets to about ¾ of an inch, you need to do something about it.

You can use a special dethatching rake or a power dethatcher to dethatch your lawn. These tools have sharp tines that cut through the thatch layer and allow you to remove it from your lawn. If your lawn has a lot of thatch, you may need to dethatch it in sections to make the job easier.

Once you have dethatched your lawn, it’s important to aerate it. Aeration involves punching small holes in the soil to allow water, nutrients, and air to reach the roots of your grass. This can be done using a manual or powered aerator rented from most garden centers or home improvement stores. If you use a power aerator, always look for a core aerator. The advantage of this style of aerator is that it will cause little damage to the lawn’s root system.

After aerating your lawn, Now it is time to decide whether or not your lawn may need to be reseeded. Spring’s mild temperature and rain make it a great time to put grass seed down. First, decide what seed will be compatible with your lawn. Next, apply the seed and if the seed is really exposed, look to cover it with Straw, topsoil or PennMulch.

After all that, it is time to think about adding essential nutrients back into the soil so your lawn can take full advantage of the Spring. you should apply a thin layer of compost or apply an organic fertilizer. to help nourish the soil and promote healthy grass growth. Compost comprises decomposed organic matter, such as leaves and grass clippings, and it is full of essential nutrients that your lawn needs. Organic fertilizers will be more potent than compost but will be made of various organic matters with a higher concentration of macro and micronutrients.

Once you have dethatched, aerated, reseeded and applied compost to your lawn, it’s time to start thinking about mowing. The best time to mow your lawn in Illinois is when the grass is dry and the blades are at least three inches tall. This will help promote healthy growth and prevent scalping, which can damage your lawn.

Use a sharp blade and set your mower to the highest setting when mowing. This will allow you to cut the grass without damaging the roots.


With these simple steps, you can get your Illinois lawn off to a great start this spring. By dethatching, aerating, reseeding, applying beneficial organic matter, and mowing your lawn, you can help ensure it stays healthy and looks its best throughout the season. Remember to fertilize your lawn and water it regularly to help it thrive. With a bit of care and attention, you’ll have a beautiful and healthy lawn that you can enjoy all season long.
