This is the reason why your lawn mower grass cuttings are clumping — and the simple fix to solve it

With warmer weather finally here, you'll want to make sure your lawn is in good shape for the summer. And while regular mowing and leaving some grass cuttings on the lawn afterwards is a great way to fertilize and put nutrients back into the soil, you could also face the issue of clumping.

Not only can it be unsightly to see large clumps of grass on your lawn, but it's also detrimental to its health. These clumps take a significantly longer time to decompose and integrate into the soil. What’s more, they can suffocate the grass underneath, causing damage and inhibiting growth.

Luckily, this is a common problem and can easily be fixed with these simple checks. Here's how to fix it for a lush and green lawn this season.

So what causes your lawn mower grass cuttings to clump?

There are several reasons, but the main reason could be cutting damp/moist grass, depending on the climate. A good way to determine this is to cut on a dry or warm day to see if clumping occurs. If it still does, then it could be down to the type of lawnmower you're using.

Typically, standard mowers will do a good job at cutting the grass, but will only spread even cuttings with sharp blades. Alternatively, you can opt for a mulching mower that is designed to disperse clump-free cuttings.

Lastly, consider how often (or little) you mow your lawn. According to experts, if you leave your grass to grow too long and then cut it short, this can result in clumping.

Easy steps to fix lawn mower clumping

Fortunately, you can quickly resolve the clumping issue and protect your grass with a few simple solutions.

The easiest one is to simply mow over the clumps of grass again to break them down. You could also shovel them up and add them to your compost bins for a cost-effective method and organic fertilizer.

Essentially, to prevent grass clippings from clumping, the key is preparation. Always be sure your lawn is dry before mowing, and maintain sharp mower blades for a clean, even cut.

Another good tip is to have a regular mowing schedule, so that you don't leave your next cut for too long. Again, this is key to preventing grass clumps and maintaining a healthy lawn.
