Should you leave grass clippings on your lawn after mowing or bag them up for disposal? Let’s face it… Homeowners often have questions about the right way to mow their lawn. “Is it better to mulch clippings or bag them when mowing?”  Sometimes it’s better to mulch clippings and leave them on the lawn. Other times, it’s better to collect them in a bag.

When you’re deciding what to do with grass clippings, it helps to understand the benefits of each option. That way, you can take care of your lawn and have a healthy, green yard all season long.

What Does It Mean to Mulch Grass Clippings?

When a mower mulches grass clippings, it cuts the clippings into small pieces that are spread evenly across the lawn.

Mulching mowers cut clippings several times until only small pieces remain. These pieces are small enough to settle between blades of grass and quickly decompose.

Many lawn mowers come equipped with mulching decks so homeowners can naturally recycle nutrients with little to no extra effort.

Why Do Many Lawn Care Professionals Recommend Mulching?

Mulching offers several benefits that improve the overall health of your lawn.

Grass clippings contain nutrients your lawn needs to grow. Nitrogen, phosphorus, and potassium are just a few nutrients returned to the soil when grass is mulched.

Mulching can supplement your lawn’s fertilization program and improve your soil quality over time.

Not only that, but mulching also cuts down on yard waste and eliminates the need to pick up and dispose of clippings.

When properly maintained, healthy lawns that are mowed regularly can greatly benefit from mulching.

Does Mulching Cause Thatch Buildup?

No. This is a common myth when it comes to lawn care and mulching.

Many people believe that allowing grass clippings to remain on their lawn will cause excessive thatch buildup. However, this isn’t the case.

Thatch consists of stems, roots, and other organic matter. These items take longer to break down than freshly cut grass clippings.

As long as you mow your lawn regularly and don’t let grass get too tall, mulched clippings should decompose in just a matter of days. They will not contribute to thatch buildup.

How Does Mulching Improve Lawn Health?

There are quite a few ways that mulching can help your lawn:

• Return nutrients to the soil
• Retain moisture by limiting evaporation
• Reduce fertilizer needed
• Improve soil organic matter
• Help lawn retain moisture
• Reduce overall yard waste
• Enhance microbial activity in the soil

Mulching can also help you grow a thicker, greener lawn over time.

When Is Bagging Grass Clippings a Better Choice?

While there are many benefits to mulching your lawn, there are times when bagging is the better option.

If grass becomes too tall between cuttings, clippings may be too long to mulch effectively. Long clippings can quickly pile up and suffocate grass.

Additionally, grass clippings should be bagged if:

• There are too many weeds in the lawn (weeds that have gone to seed)
• Grass is wet and clumping
• Disease is prevalent throughout the lawn
• There is an excessive amount of leaf debris mixed in with grass.
• You want to perform a “clean-up” cut at the end of the season

Instead of mulching, these grass clippings should be bagged so they don’t lead to additional issues.

Can Mulching Help Reduce Fertilizer Costs?

Yes! Since grass clippings contain many nutrients, each time you bag and throw away clippings you’re removing nutrients from your lawn.

Mulching returns some of those nutrients to the lawn and decreases your lawn’s dependency on fertilizers.

Mulching won’t eliminate fertilizer applications, but it can lead to a healthier lawn.

Does the Frequency of Mowing Matter?

Yes! Mowing your lawn too far in between can cause problems for mulching.

Follow the one-third rule and never remove more than one-third of the grass blade at a time. Cutting off too much of the grass will result in large clippings that aren’t distributed evenly.

Big piles of clippings take longer to break down and can prevent sunlight from reaching the grass beneath.

Mowing regularly gives you the benefits of smaller clippings that decompose faster.

What About Wet Grass?

Wet grass can cause problems for mulching and bagging.

When grass clippings are wet, they tend to stick together. When this happens, it’s hard for the mower to spread clippings evenly across the lawn.

Small clumps of grass can also kill turf and leave your lawn looking uneven.

Ideally, you should mow when the grass is dry. Dry clippings spread better, decompose faster, and leave your lawn looking clean.

If you can’t mow when grass is dry, bagging clippings may be a better solution.

Are There Environmental Benefits to Mulching?

Yes! Mulching is one of the most environmentally friendly ways to mow your lawn.

Instead of throwing grass clippings in the trash (or sending them to the landfill), mulching allows you to reuse them and put nutrients back into the soil.

Since mulching can also reduce your lawn’s need for fertilizer, mulching might even reduce your lawn care impact on the environment.

Mulching is a great option for homeowners who want to practice environmentally friendly lawn care habits.

How Can You Get the Best Results When Mulching?

To mulch effectively, you must properly maintain your lawn.

Follow these steps to ensure you get the most out of mulching:

• Sharp mower blades
• Mow regularly (especially during the growing season)
• Do not remove more than one-third of the grass height when cutting
• Mow grass when it’s dry if possible.
• Adjust your mower to the appropriate height for your grass type.
• Don’t allow grass to become too tall between cuttings.

Mowing properly will ensure you get smaller clippings that spread evenly and decompose quickly.

So, Is It Better to Mulch Clippings or Bag Them When Mowing?

Mulching is better for most healthy lawns. Mulching returns nutrients to the lawn, helps improve soil quality, and cuts down on yard waste. When done correctly, mulching your lawn can help you grow a greener lawn while putting in little effort.

That being said, sometimes bagging grass is the better option. Bagging grass helps prevent thatch buildup, gives your lawn a nice clean look, and can help you manage lawn diseases.
