How To Eliminate Crabgrass In The Spring – And Stop It For Good!

One of the best ways to eliminate crabgrass for good is to never let it sprout and grow in the first place – and as it just so happens – early spring is the perfect time to make that wish come true!

If you are tired of watching crabgrass overtake your lawn every summer and fall, then this is the year to take action. And spring is THE time to do it! Unfortunately, waiting until your lawn springs back to life means missing your chance to get crabgrass under control. And if you don’t – your problem only multiplies.

Crabgrass can be a nightmare to keep at bay. The fast growing weed branches out quickly from its main stem. As it does, new roots form from nodes on its sprawling branches. Before your know it, a single sprout becomes a large mass of yellowy-green grass. And can it ever stick out like a sore thumb – especially against the darker green blades of the natural green grass growing in your lawn.

Once crabgrass sprouts in the spring – it’s difficult to control. But if you stop it from coming up – you can stop it for good!

With over 30 varieties of invasive crabgrass that grow in all types of climates, the weed can pop up anywhere. When you add in that once established, mature plants can produce thousands of seeds, it’s easy to see why it can be so hard to eliminate.

The good news is that you can gain the upper hand on crabgrass. And best of all, you don’t even have to resort to harsh chemicals or sprays to do it. In fact, there are several 100% organic products that work wonders in keeping crabgrass from ever having their first bit of growth!

How To Eliminate Crabgrass In The Spring – And Stop It For Good!

The biggest key of all is to start attacking the issue of crabgrass in early spring, before all of those dormant seeds lying in your yard begin to germinate.

Why is early spring so critical in the fight against crabgrass? Because if you can treat the seeds before they sprout, crabgrass has no chance of survival. It won’t be able to sprout. Nor can it grow and produce even more seeds to spread around your lawn.

As you will see below, there are several additional steps you can take throughout spring, summer and fall that can help to eliminate crabgrass from your lawn – but success all starts with putting down a pre-emergent in early spring to keep the stubborn weed from germinating.

Once crabgrass sprouts, the trouble begins! Each plant can produce thousands of seeds.

Using A Pre-Emergent Treatment – How To Eliminate Crabgrass In The Spring

The best way to keep crabgrass seeds from germinating is by using a pre-emergent product on it. What is a pre-emergent? It’s simply a substance that stops a seed from being able to sprout. By sterilizing the seed on contact, it then becomes unable to germinate.

Although there is a long list of synthetic man-made pre-emergents on the market, they can be a bit iffy when it comes to using around children, pets and even adults. We like to keep our farm 100% organic. Luckily, when it comes to pre-emergent crabgrass control, there are a couple of great all-natural solutions that really work well.

One of the best all natural pre-emergents for crabgrass is corn gluten. Even better, it also happens to prevent many other common weeds from germinating as well in a lawn. As if that wasn’t enough, corn gluten contains around 10% nitrogen.

That means not only can it work as a pre-emergent, but it can also provide power to your lawn. It is a win-win for sure, but again, the key is getting the pre-emergent down before the seeds sprout!

Applying Pre-Emergents – How To Eliminate Crabgrass In The Spring!

In order for the corn gluten (or any pre-emergent) to work, it must be put down before (pre) the crabgrass begins to emerge and grow.

Once crabgrass and other weed seeds germinate, a pre-emergent will not work. It is not an herbicide, but instead a way to prevent the crabgrass from starting to grow. Because of that, you need to get the product down early, before your grass ever starts to even begin to green up.

For us here in Ohio, that means the first part of March. To apply, you can use a drop or broadcast spreader. We always prefer broadcast spreaders as they more evenly coat the grass. Always check the product bag for recommended rates before applying.

For large yards, you can often find bulk corn gluten as an economical choice. We use the Espoma brand and apply it to our main lawn area at a rate of about 20 lbs. per 1,000 sq. ft. Affiliate Product Link: Espoma Organic Weed Preventer

Mow Before You Apply

Before applying, it’s actually a great idea to first mow your lawn to get it to a lower, more even height. This will allow the product to find it’s way to coat the entire surface of the lawn. The product sticks better when the grass is slightly wet, so applying when there is early morning dew is great. You can also lightly water it in if your lawn is small enough to do so.

There are many corn gluten products available for putting on your lawn to stop crabgrass. We have had good success with this Espoma product – with little worry of harming pets or people.

Here is the best part of using an organic product, it is safe for pets or children immediately. With that said, we always try to limit walking traffic for a few days just to get the product to stick better and not disturb it.

A Few Additional Tips & Tricks – How To Eliminate Crabgrass In The Spring

Like any application, how effective a pre-emergent will be can vary on when it is put down and the overall coverage. It is quite impressive just how much it can prevent with a first application, but it can take a few years to really knock it out. Again, like with any gardening task, consistency is the ultimate key to success.

There are other important factors in how crabgrass grows and spreads that you can help control throughout the growing season. First and foremost, how you mow your lawn can play a big role in keeping crabgrass at bay, or in helping it to spread.

Mowing your lawn high is one of the best things you can do for your turf’s overall health. It helps keep valuable moisture in the soil and keeps weed seeds (like crabgrass) from finding a home.

In addition, a higher lawn creates a thicker lawn, which blocks sunlight from the soil. That is extremely critical in helping to stop crabgrass as it needs sunlight to germinate. For best results, try to keep your lawn height between 3 to 3.5 inches throughout the growing season.

Keeping a lawn between 3 and 3.5 inches helps keep weeds like crabgrass out – and helps to keep moisture in.

A Little Extra Effort Goes A Long Way – How To Eliminate Crabgrass In The Spring

Finally, one of the best ways to really get the upper hand on crabgrass is to hand pick any large plants that remain. Especially before they can produce their seed heads. And those seed heads can spread it fast!

Crabgrass is quite easy to spot in the summer and early fall months. It also is fairly easy to remove with a small weeding fork or shovel. Once you pull the plants, it’s a great idea to throw down a bit of grass seed to help fill in the bare spot.

Here’s to preventing an onslaught of crabgrass this spring, and to stopping crabgrass from taking over your lawn this summer and fall! Happy Gardening – Jim & Mary.
