How to Make The Grass In Your Lawn Green and Thick (And Keep It That Way!)

Having a beautiful, attractive lawn feels so rewarding, so it can be very frustrating when it's not in tip top shape.

If you're not happy with your lawn's health or overall appearance, then you'll want to keep in mind some of the tips we're about to share. We'll teach you how to make the grass in your lawn green and thick and how to keep it that way so you can proudly show it off to your guests and neighbors.

Improve The Soil

The first step in growing healthy grass is making sure your soil conditions are optimal for growing healthy grass. Without the proper soil, grass will not grow as well and as a result, things like moss, mushrooms, creeping charlie, clovers, and other weeds can grow and take over the lawn.

Step 1: Test Your Soil

Ultimately, your best next steps should be determined by the results of the soil test. That said, we've included steps 2 and 3 below as general guidance that applies to the most common soil quality problems.

First, get a soil pH testing kit such as this one and read the results yourself, or get a kit like this one and send your soil to a lab to get tested. The soil should be neutral or slightly acidic in order for grass to grow properly. Getting the soil tested first will help you decide what you need to change.

Step 2: Aerate Your Lawn

If it was possible to dig up the entire lawn and start with brand new soil, that would be the surest way to ensure a proper environment for healthy grass to grow. But for most people, digging up your lawn is not only impossible but also simply impractical.

That's why aeration is so common. During the process of aeration, you use a device called an aerator to dig out a lot of narrow holes in the lawn. This prepares the lawn for receiving deposits of fertilizer rich soil (the next step).

Depending on how poor your soil quality is, you may need to aerate your lawn 2 or 3 times a year, ideally during spring.

Step 3: Add Fertilizer

After you've aerated the lawn, it's time to add fertilizer rich soil to fill in the holes. We once again recommend that you determine the proper soil additive based on the soil test kit results.

That said, a common solution is to use organic compost (you can make this yourself using a compost bin, or buy bags of compost from a local lawn and garden supplier) mixed with a small amount of nitrogen fertilizer.

But if your soil has a lot of clay in it, you may want to mix in a fertilizer that's designed specifically for clay rich soil, such as Aerify PLUS. That kind of fertilizer is designed to work itself into the clay and break it down so it becomes more soil-like, which is a much more long-term solution than using traditional fertilizer.

Get Rid of Weeds

Often times, the reason weeds take over a lawn is that the soil is not providing the proper balance of minerals and nutrients for grass to grow and flourish.

So if you want to get rid of weeds long-term and get your grass to grow luscious, vibrantly green and thick, we recommend both getting rid of the weeds and improving the soil quality, since both go hand in hand.

There are quite a few weeds and pests that can cause problems in the lawn. Below we've listed articles that will help you deal with those pesky weeds. Just click on the problem below to read our full explanation of how to solve it.


The purpose of over-seeding is to proactively plant grass in empty spots in your lawn so that grass grows there instead of weeds.

To prep for overseeing, first mow your lawn at low setting your mower has, and use a bagger to catch the grass so none of the clippings fall in the lawn. This gives the grass seed (future step) a better chance at growing.

If there are any major clumps of weeds or moss in the lawn, remove as much of that as possible next. You may want to consider dethatching before overseeding.

Finally, apply grass seed generously. A grass spreader can make this job not only easier but more effective because it evenly distributes the seed on the ground.

To give the new grass an extra "boost" so it grows faster, you may want to add a grass "feed" fertilizer after you've applied all the seed. This isn't absolutely necessary but could make the grass grow faster so you don't have to spread seeds as often.

You may also find it helpful to water your lawn once or twice a day, particularly in the patches where you scattered the grass seed, until the new grass is as tall as the rest of the grass in the lawn.


Can I put down too much grass seed?

Yes, too much seed can make it difficult for the new grass to grow properly. The seeds can crowd out each other preventing some from sprouting, and the ones that do grow can have poor structure because of being so crowded.

What happens if I water my lawn too much?

If the soil becomes too saturated with water, fungus can grow and rot the grass' roots. You may notice patches of your lawn turning yellow or dying, which could be a sign of too much water, either from excessive watering or too much rain.


There you have it! That's how to make the grass in your lawn green and thick.

Keep testing the soil, getting rid of weeds, and overseeding when needed, and you'll keep your lawn looking fresh and green.

Hey it's not our fault if you start getting jealous glares from your neighbors who wish their yard was as beautiful as yours! (don't say we didn't warn you)
