How to Make Leaf Mulch for Your Garden With Fall Leaves
Fall leaves don’t have to go to waste! Learning how to make leaf mulch is an easy, budget-friendly way to recycle fallen leaves instead of bagging them up and sending them away.
Leaf mulch helps protect your soil, retain moisture, and add organic matter to your garden as it breaks down. Mulching leaves is a great way to prevent cold-tolerant weed seeds from sprouting over the winter, and will help your soil hold moisture next year. Best of all – as long as you have trees in your yard – it’s free!
You can make leaf mulch using a lawn mower or other methods to shred leaves into smaller pieces. In this guide, I’ll show you how to make mulch from leaves, how to compost these leaves in a compost bin, and share practical ways to use this natural mulch in your garden.
I’ll also explain the difference between leaf mulch, leaf mold, and compost so you can choose the best option for your plants.

How to make leaf mulch
Making leaf mulch is easy to do by gathering fallen leaves and then shredding them into smaller pieces so that they don’t mat together and block air and water when you use them in your garden.
Best leaves for leaf mulch
Leaves from deciduous trees make great leaf mulch.
- Maple leaves break down quickly and help with soil aeration.
- Birch leaves decompose fast and add a boost of nitrogen.
- Poplar leaves also break down quickly.
- Elm leaves decompose quickly and enrich the soil with calcium and nitrogen.
- Oak leaves take longer to decompose and are ideal for acid-loving plants.
How to collect leaves for leaf mulch
- Collect dry autumn leaves on a calm day using a rake or a leaf blower.
- If you don’t have enough leaves on your own property, you can ask neighbors who put their leaves out for collection in the fall to share them with you.
Shredding leaves with a shredder
The quickest and easiest way to mulch leaves is with a leaf shredder. A leaf shredder, also known as a leaf mulcher, is a machine designed to shred and reduce fallen leaves, twigs, and small branches into smaller pieces or mulch.
These devices are especially handy during the fall season when there’s an abundance of fallen leaves in the garden.
- To use the leaf shredder, first rake your leaves into a pile.
- Try to do this when the leaves are dry since they will break down more quickly and shred more easily.
- Use the leaf shredder to grind the leaves, catching the pieces in a bag or large container.
Using a lawn mower to mulch leaves
If you don’t have a shredder, you can use your lawn mower to shred the leaves.
- To mulch leaves with a lawn mower, rake the leaves into layers a couple of inches tall.
- Run the lawn mower over them several times. This will turn them into progressively smaller pieces.
- Place these shredded leaves in a bag or large container.
How to shred leaves by hand without a shredder
If you don’t have a shredder or lawn mower, you can shred leaves by hand with a string trimmer. This is a good way to do small batches of leaves.
- Place the leaves about one-third to halfway in a deep container.
- Use safety glasses, insert a string trimmer into the bin, and turn it on.
- Move the trimmer around the container, trying to mix the leaves to catch the top and bottom layers.
No matter which method you choose to mulch the leaves, be sure to be safe and wear gloves and use eye protection.
Adding the shredded leaves to a compost pile or bin
Once the leaves have been shredded, you can use them in your garden immediately. To take the process a step further, you can add them as part of the brown material in a compost bin.
- Layer the shredded leaves in a pile, compost bin, or designated leaf compost area.
- Keep the pile moist but not soggy.
- Turn the pile occasionally to aerate it and promote decomposition.
- Mix in other organic matter, such as kitchen scraps or grass clippings, since this will quicken the composting process.
How to use leaf mulch in your garden
This shredded material can be used as leaf mulch, which is beneficial for garden beds and for composting.
- Place piles of the leaf mulch around the crowns of plants, about 2-4 inches deep. Try to keep the leaf mulch about one inch away from the crown itself.
- I like to use fresh leaf mulch around garlic that was planted in fall to protect it over the winter months.
- You can also place the shredded leaves on bare areas of your garden beds to help control weeds.
- Regularly check the mulch layer for weeds and add more mulch if it begins to thin out.
- You can also place any leftover shredded leaves into bags. Over time, they will decompose further, turning them into leaf mold, which is even more beneficial in a garden.
- If you are using shredded leaves that have been composted, you can dig this into the soil around your plants to use as a natural fertilizer.
How long do leaves take to decompose?
The time it takes to make leaf mulch can vary depending on several factors, including the level of decomposition you desire and the method you use.
Here’s a general overview of the different stages of mulching leaves and how long they take:
- Fresh leaf mulch: This is essentially just shredded leaves that have not undergone any significant decomposition. You can start using fresh leaf mulch almost immediately after shredding the leaves.
- Partial decomposition (Leaf Mold/Mould): If you want to create leaf mold or leaf mould, which is more decomposed and nutrient-rich, this process can take several months to a few years. The leaves will need to break down naturally, and this depends on factors like temperature, moisture levels, and the types of leaves used.
- Composted leaf mulch: If you incorporate shredded leaves into a compost pile, the leaves can break down much more quickly, typically within several months, especially if you maintain the compost pile properly. Mixing leaves with other organic matter and turning the compost pile regularly can speed up the process.
Can you use whole leaves as mulch?
As tempting as it might be to just scoop up some leaves and add them to your garden beds, this isn’t very effective. If you do this, the leaves will become matted, and this could actually hurt your garden instead of helping it.
Instead, you will need to shred the leaves to turn them into inexpensive mulch that can be used next spring.
Leaf mulch benefits
Leaf mulch is a natural and sustainable way to protect and nourish your garden. Some of its benefits are:
- Soil enrichment: Leaf mulch improves soil structure, adds essential nutrients, and enhances water retention, promoting healthier plant growth.
- Weed suppression: A layer of leaf mulch acts as a natural weed barrier, reducing the need for weeding sessions.
- Moisture regulation: Leaf mulch helps maintain consistent soil moisture by reducing water evaporation, which is especially beneficial during dry spells.
- Insulation for roots of plants: Shredded leaves provide a blanket for plant roots and rose bushes, protecting them from extreme temperature fluctuations in both summer and winter.
- Eco-friendly: Using leaves as mulch reduces waste and contributes to a more sustainable gardening approach.
Leaf mulch vs leaf mold vs leaf mould vs compost
All three terms, “leaf mulch,” “leaf mold,” and “leaf mould,” refer to the same gardening material – leaves. However, they may have slightly different connotations in various regions and contexts.
- Leaf mulch – This term generally refers to freshly fallen or shredded leaves used as a mulch in gardens. In this context, “leaf mulch” typically describes the less decomposed leaves.
- Leaf mold (or leaf mould) – This term usually refers to partially decomposed or well-rotted leaves that have broken down over time. Leaf mold is a valuable organic material that is rich in nutrients and can be used to improve soil structure and fertility. It’s often considered a more advanced stage of decomposition compared to “leaf mulch.” Think of it as a material more like compost.
- Compost – This term refers to a dark, crumbly mixture of decayed organic matter, typically food scraps, yard waste, and leaves. The mixture breaks down by microorganisms, often in compost piles.
Leaf mulch (or leaf mold) is eco-friendly and helps create a thriving ecosystem in your garden.
In practice, gardeners often use the terms leaf mulch and leaf mold (or leaf mould) interchangeably. Today, we’ll be learning about how to help nature break down fall leaves by shredding them for use as composted mulch.
