You’ve cut your grass, and now you’re wondering what to do with the clippings. You might think of tossing them in the garbage.

However, this is not a good idea and it is actually not allowed in most regions. The best thing to do is to leave grass clippings of an inch or less in length on the lawn, where they will filter down to the soil surface and disintegrate quickly.  Longer clippings should be removed because they can shade or smother the grass beneath, causing lawn damage.

That being said, there’s a lot more you could do with grass clippings than simply raking them up and tossing them in the garbage.

Utilizing grass clippings in your vegetable patch or flower bed can make it healthier while also repurposing your yard’s waste in an environmentally friendly manner.

Why Is It a Bad Idea to Dump Grass Clippings?

Additionally, grass clippings and yard waste produce heat. This is caused by microscopic bacteria and fungi that feed on moist grass clippings.

Freshly cut grass spread across a lawn begins to rot, but you won’t notice the heat it produces until you rake the grass into a pile.


Have You Noticed: The larger the stack, the more heat is trapped, and the pile temperature rises. If these clippings are piled together with other garbage, it might potentially ignite.


How to Reuse Grass Clippings?

Grass clippings are far too valuable to be thrown away.

Leaving grass clippings on the lawn after mowing allows them to decay within a few weeks.

While it may appear to be a good idea to fasten a bag to the grass cutter to collect grass clippings and remove the annoying little green bits that is left behind, this is a bad idea.

Grass clippings should be placed throughout the lawn and used as a natural fertilizer.

Grass clippings decay quickly and bring back crucial nutrients to the soil.

Few lesser-known facts:

  • Grass clippings and extra yard waste account for 12% of hard waste in landfills across the United States. During high season, that percentage can rise to 50%.
  • Throwing yard waste and grass clippings is both wasteful and costly.
  • Instead of using yard waste as an organic fertilizer for their lawns, taxpayers spend a lot of money collecting and transporting it to the landfills.

Things to Consider When Grasscycling

When the grass is dry, cut it.

Mowing a wet yard is difficult because the grass is weighty and will not provide a good cut. A dry cut will aid in the efficient dispersal of clippings.

Keep the mower’s blade sharp. A sharp blade promotes a clean cut, which keeps diseases and insects at bay in the yard.

If there is too much growth in between clippings, lift the mower height and slowly lower it for subsequent clippings.

A dramatic cut will shock the grass, whereas a moderate cut will keep the grass healthy.

After mowing the grass, there is no need to collect the grass clippings. Leave them alone; the small clippings will eventually fall into the deeper surface of your lawn.

If your yard has been herbicide-treated and you intend to use grass clippings as mulch, wait for at least three cutting grass sessions before using the grass clippings.

Grass Clippings Dos & Don’ts

How to Dispose Grass Clippings?

1. Composting or Mulching Grass Clippings

Nitrogen-rich grass clippings make excellent compost materials.

When added to a compost pile, it produces a balanced carbon and nitrogen content and high-quality fertilizer. As a result, your plants will grow healthier.

In addition to compost, you can use grass clippings to make mulch. Mulch not only adds nutrients to your soil but can also prevent weeds from growing.

2. You Can Leave them on Your Lawn

The best way to get rid of grass clippings is to leave them in your yard.

In this case, you should mow the grass regularly rather than wait until it grows too long.

Allowing grass clippings to fall to the ground will naturally help feed the soil in your yard. As a result, your lawn will be healthier.

This is also the best alternative because it does not necessitate any additional effort.

Aside from farmers, you can also speak with a local gardener. Grass clippings are also commonly used to make compost or mulch.

4. Use Them to Top Dress Raised Beds

They aid in the retention of moisture in your beds, weed suppression, and organic fertilizer addition to your plants.

Try spreading a few inches across the surface of the beds.

The height of the mulch will decrease as the clippings decay. Throughout the growing period, add more as needed.

5. Deliver Grass Clippings to a Local Disposal Facility

If your regular garbage disposal service allows it, the simplest way to dispose of grass clippings is to place them in your yard waste bin.

However, because not all waste disposal organizations want to haul your lawn trash, you should separate it from your regular trash can.

Aside from that, some trash collection companies can charge extra for yard waste.

As a result, you may need to consult with the garbage collector first.

Final Thoughts

Leaving grass clippings on the yard does not result in thatch, a layer of partially decomposed grass-plant parts between the live grass and the soil.

Grass clippings are mostly water, so as long as you cut the grass at the proper height regularly, they will degrade and disappear quickly.  

If your yard has any illness or fungal infestation, such as Brown Patch Lawn Disease, do not let grass clippings fall on it after mowing.

This will only motivate the disease or fungus to continue to spread, allowing it to infect a wider area of your lawn.

By removing the clippings, you are assisting in the reduction of the population level of deleterious organisms.
