Before we learn about the different types of mulch for landscaping and types of mulch for gardens, let’s first define what mulch is. Mulch is a protective layer spread over the soil to cover it. It has several important jobs. First, mulch helps keep moisture in the soil by stopping too much evaporation. Second, it insulates the soil, keeping it cooler in hot summer and warmer in cold winter. Mulch also stops weeds from growing and prevents soil erosion.
Types of Mulch for Landscaping and Gardening
When doing landscaping or gardening in Canberra, there are many different types of mulch you can use. Each kind has its own good points and not-so-good points. Let’s look at some common mulch options:
Organic Mulches
Organic mulches come from natural stuff that decomposes (rots down) over time. As they decompose, they add nutrients to feed the soil.
1. Wood Chips or Bark Mulch
One of the most popular mulches is made from shredded tree bark or wood scraps. These wood chip mulches last a long time and are great at keeping moisture in the soil. But they can temporarily use up some nitrogen in the soil as they decompose.
2. Leaf Mulch
Leaf mulch is made from shredded leaves. It’s a cheap option and adds lots of nutrients to the soil as it rots down. But leaf mulches can get compacted over time, so you may need to add more often.
3. Grass Clippings
Using grass clippings as mulch is an easy way to recycle this natural material. Grass breaks down quickly, giving nitrogen to the soil. But thick layers of grass clippings can get matted and smelly.
4. Straw Mulch
Straw mulch comes from the stalks of crops like wheat, oats, or rice. It’s a lightweight, easy-to-apply mulch that decomposes slowly. Straw is good at stopping weeds but can blow away if it’s windy.
Inorganic Mulches
Inorganic mulches are non-biodegradable materials that don’t rot. They don’t add nutrients to the soil but can last a very long time.
5. Rock or Gravel Mulch
Rock or gravel mulches look very neat and uniform. They’re durable and you don’t need to add more often. But they can absorb and give off heat, warming up the soil more than you might want.
6. Rubber Mulch
Recycled rubber mulches are made from shredded up old tires. They last a really long time and are excellent at retaining moisture. However, they can be expensive and might contain chemicals that could leak into the soil.
Picking the Right Type of Mulch for landscaping
When choosing a mulch for your landscaping or garden, think about things like cost, how it looks, how long it lasts, and its impact on the environment. Organic mulches are usually more environmentally friendly since they feed the soil as they rot down. But inorganic mulches can last longer and might be better for some situations.
No matter which mulch you pick, putting it down properly is important. Apply a 2-4 inch layer around plants and trees, leaving a little space at the base to prevent rotting. Add more mulch as needed to keep the desired thickness.
Why Use Mulch for gardening?
Using mulch in your landscaping and garden gives you lots of benefits:
- It keeps moisture in the soil by stopping too much evaporation.
- A thick layer stops weeds from growing by blocking sunlight.
- Mulch keeps soil temperatures from getting too hot or too cold.
- It covers the soil to prevent erosion from wind or rain.
- As organic mulches rot, they release nutrients into the soil.
- Mulch makes landscaping beds and gardens look neat and finished.
In Canberra’s climate, mulching is really important for saving water and keeping temperatures steady. By using the right type of mulch, you can create a healthier, more environmentally-friendly home for your plants.
