Cutting grass and leaving clippings can be a simple and effective way to maintain a healthy lawn. This approach can save you time and money, as you won't need to spend money on fertilizers.

A key benefit of leaving clippings is that it reduces the need for frequent mowing, as the clippings act as a natural fertilizer, promoting healthy growth. This can be especially beneficial for lawns with a mix of grass types.

Leaving clippings can also help reduce soil erosion, as the clippings act as a natural mulch, holding the soil in place. Regular mowing can damage the soil and lead to erosion.

By leaving clippings, you can also reduce the amount of waste sent to landfills, as the clippings can be used as a natural fertilizer and soil amendment.

Benefits of Recycling to the Lawn

Recycling grass clippings to the lawn is a simple yet effective way to give your lawn a boost. By leaving the clippings on your lawn, you can reduce the need to use nitrogen fertilizer.

Clippings are a valuable source of nutrients, rich in nitrogen and other essential nutrients that are slowly released as they decompose. This avoids burning your lawn and can save you time and money by reducing the amount of chemical fertilizer you need to apply.

Regular mowing will greatly reduce the need to collect clippings. Aim to cut no more than 1/3 of the grass height at a time to keep your lawn healthy and prevent the need for excessive fertilizer.

Some benefits of recycling clippings to the lawn include:

  • Reduced need for nitrogen fertilizer
  • Improved soil quality, especially for sandy, heavy clay, or low-organic-matter soils
  • Less frequent need to rake and bag clippings

If you have chickens, leaving the clippings on your lawn will provide them with fresh greens to eat, protecting the roots from their digging and scratching.

Cutting and Mulching Options

There's no clear-cut answer on whether to mulch or bag your clippings, as it depends on the situation. Mulching is a great way to return moisture and nutrients into the lawn, but it can also form a thatch of dead grass that blocks air and light.

Some experts argue that leaving clippings on the lawn is beneficial, while others maintain that it's better to bag them. In general, putting mulch around flowers, vegetables, shrubs, and trees helps reduce weeds, conserve moisture, and moderate soil temperatures.

Grass clippings are a good mulch option, but be sure to follow some conditions. Here are the key things to keep in mind:

  • Don't apply more than 1 or 2 inches of grass clippings at one time.
  • Use dry clippings – wet grass clippings can mat down and reduce oxygen and moisture from getting into the soil.
  • Don't use grass clippings as mulch if the lawn was recently treated with an herbicide for dandelions or other broadleaf weeds.
  • Check the herbicide product label for any concerns related to using clippings as mulch.

Remember, it's all about finding the right balance and being mindful of the conditions on your lawn.

Composting and Thatch

Leaving clippings on the lawn does not contribute to increased thatch. Thatch is a layer of undecomposed organic matter that builds up between the soil surface and the actively growing green vegetation.

Contrary to popular belief, clippings are composed of water and easily-degradable compounds that break down rapidly and do not accumulate. Long clippings may contain wiry stem material that is slower to decompose, but are still not significant contributors to thatch buildup.

Grass clippings are excellent additions to a compost pile because of their high nitrogen content. To compost clippings effectively, mix them with dry materials such as leaves or straw to avoid anaerobic decomposition and bad odors.

Composting is a great way to turn your lawn clippings into a nutrient-rich soil amendment. You can add clippings to your backyard compost pile.

Grass clippings are excellent additions to a compost pile because of their high nitrogen content. However, they shouldn't be the only compost material, as this can lead to bad odors from anaerobic decomposition.

Mixing grass clippings with dry materials like leaves or straw is a good idea. This helps to balance out the moisture levels and prevents anaerobic decomposition.

Lawn clippings can usually be composted and work especially well with brown materials like dead leaves. They're mostly water, so they help to heat up the compost and speed up the decomposition process.

Avoid adding lawn clippings to compost if you've recently applied lawn pesticides, fungicides, or herbicides. It's best to put these clippings in the rubbish bin for at least three more mowings after applying these products to your lawn.

Thatch is a layer of undecomposed organic matter that builds up between the soil surface and the actively growing green vegetation. A thatch layer will develop if organic matter is produced faster than it is decomposed.

Leaving clippings on the lawn does not contribute to increased thatch.

Best Practices and Disadvantages

To maintain a healthy lawn, it's essential to follow best practices when it comes to leaving grass clippings. You should only mulch when you're trimming the lawns, as this allows the clippings to act as a replacement fertilizer.

To avoid leaving too many clippings, position your cutting deck to remove only the top one third of your grass blades. This will prevent the clippings from smothering your freshly cut grass.

If you're not able to mow regularly and the grass becomes longer than 7 cm in height, it's better to bag the clippings and dispose of them to prevent the growth of diseased grass.

The main disadvantages of leaving grass clippings on your lawn include:

  • The grass is wet, making the clippings stick together.
  • The piles are too thick and can become matted.
  • There are patches of diseased grass on your lawn.

These can lead to the development of fungal diseases in your lawn, especially in areas prone to high rainfall and humidity.

Best Practices

To get the most out of your lawn, it's essential to follow best practices.

Leaving clippings on the grass can act as a replacement fertilizer, but only if you're not overdoing it.

Position your cutting deck to remove only the top one third of your grass blades when you're trimming the lawns.

If you're not able to mow regularly, bag the clippings and dispose of them if your grass grows longer than 7 cm in height.

This will prevent your freshly cut grass from being smothered by diseased grass that could impact new growth beneath.

Disadvantages of Leaving Grass

Leaving grass clippings on your lawn can have some serious drawbacks. The clippings can stick together if they're wet, making a big, matted mess.

If the clippings are too thick, they can restrict airflow to the grass underneath, leading to fungal diseases like Fusarium Patch and Brown Patch.

Longer grass clippings tend to sink into the thatch layer, making it spongy and holding water that should be absorbed into the soil instead.

This can cause problems like waterlogging and require more frequent dethatching, which can be expensive and time-consuming.

Clippings from diseased grass can even encourage the disease to spread across your lawn, so it's best to collect and bin them immediately.

Here are some common fungal diseases that can develop on your lawn due to wet or thick grass clippings:

  • Fusarium Patch
  • Brown Patch
  • Dollar Spot
  • Powdery Mildew
  • Pythium Blight

Equipment Guide

Rotary lawn mowers are the most common type of mower used in suburban Australian yards.

They are easy to operate, widely available, and relatively inexpensive.

Rotary lawn mowers can be a bit noisy, but they get the job done.

Frequently Asked Questions

Does putting grass clippings on bare spots help grass grow?

Yes, putting grass clippings on bare spots can help grass grow as they release nitrogen and other nutrients back into the soil. This natural fertilizer can support new grass growth and promote healthy lawn development.

What happens if you don't pick up grass clippings?

Not collecting grass clippings can actually improve lawn quality by returning nutrients to the soil as they decompose
