Overseeding in Spring for Thicker, Greener Grass

One of the most effective ways to rejuvenate your lawn after a long, cold winter is by overseeding in Spring. Overseeding is the process of planting grass seed directly onto your existing lawn to enhance its density, appearance, and overall health.

In this article, we’ll provide a step-by-step guide on how to overseed your lawn in Spring to achieve the thick and vibrant lawn you’ve always wanted.

Overseeding in Spring

As you can see from the video linked below my lawn does not look great at the moment

I’ve recently overseeded and top dressed the lawn with a sandy mix and this is just really to level off any of the bare spots you can see in your grass.

By combining top dressing and overseeding you can achieve great results because the top dressing mix will help provide a good bed for the seeds to sit in and will also reduce take from the birds.

When the new growth comes through it will cover any top dressing that you’ve put down on your lawn and will blend it all into one.

Step 1 – Cut your Grass

The first step is to cut the lawn down to a low height, this is going to make it easier for the seeds to come in contact with the soil bed.

Another benefit of cutting your grass is that when you come to apply leveling over the top of it you’re not applying it over thick grass so when the new growth comes through it can pierce through the top dressing layer that you put on and blend in with the existing lawn.

Step 2 – Overseed your lawn

After you’ve cut the lawn the next step is to overseed the lawn, i normally do this in two passes similar to how I would apply lawn fertiliser

This means doing one pass in a horizontal direction and the other pass in a vertical direction just to make sure you’re getting really good coverage and you’re not missing any spots.

Step 3 – Applying top dressing

The next step is to apply the top dressing to your grass which is relatively simple.

If you’ve got a large area to cover you can buy a bulk bag of top dressing mix and then broadcast it using a spade. For a smaller areas you can buy small bags of top dressing mix.

I find using a straight piece of wood just to drag along the surface helps to spread the product evenly across the lawn. You can also use a rake or a broom just to help push that grass into the surface.

Overseeding Results

After about a week or so you’ll start to notice the growth coming back through, this will be especially boosted by the application of lawn fertiliser we applied in part one of spring lawn care guide.

When the grass seeds are around 1-2 inches long (2 to 5 cm) you can start cutting them with your mower. Make sure the ground isn’t too wet and your mower blades are sharp.
