Mulch is an often underrated but also highly impactful way to keep your landscape looking its best. When it comes to mulch, the benefits go far beyond looks. Did you know that spreading mulch or tree chippings over the soil around plants and trees will also help conserve moisture, suppress weeds, and regulate soil temperature? It really is a miracle material!

Calculating how much mulch you need

Yet, before you can start spreading your mulch, you’ll first need to figure out how much mulch you need. Some people find this part daunting to determine, but not to worry. There are some quick calculations you can do to figure out the quantity of mulch required – based on the size of the area you want to cover, as well as the depth you want to apply it. This will help you purchase the right amount of mulch (without overbuying or underbuying) so you don’t come out short or end up with far too much. To help you get it right, we’ve created a step-by-step guide to help you calculate how much mulch you need:

Step 1: Measure the area you want to mulch

The first step to calculating how much mulch you need, is to measure the area you want to mulch. Use a measuring tape to measure the length and width of the area. If the area is irregularly shaped, you’ll need to divide it into smaller sections and measure each section separately. Next, simply add up the total area to get the overall measurement.

Step 2: Decide on the depth of mulch

The depth of mulch you need depends on the type of plants you’re growing, the climate in your area, and the type of mulch you’re using. Generally, a depth of 5-10cm is sufficient for most plants. If you’re using a heavier mulch, such as wood chips or bark, you may need a thicker layer of mulch to achieve the same benefits.

Step 3: Use a mulch calculator

Now that you have the measurements and depth, it’s finally time to calculate how much mulch you’ll need. The formula for mulch calculation typically involves multiplying the length, width, and depth of the area you plan to cover (Mulch Amount = Length x Width x Depth). If you don’t feel like doing the maths yourself, there are several mulch calculators available online, and most of them are free to use. Just make sure all measurements are in the same unit, for example metres or centimetres, before hitting calculate.

Step 4: Buy the right amount of mulch

Once you know how much mulch you need, it’s time to buy it. Mulch is usually sold by volume. You can buy mulch from a local garden centre, online, or we can sort this out or you.

How to use mulch

Adding a layer of mulch creates a fresh, clean and newly-planted look that will make any garden look great – but did you know the benefits of mulch go much deeper than the surface? Mulch has many benefits, including:

  • Moisture retention – Mulch helps to retain moisture in the soil, reducing the need for frequent watering.
  • Weed suppression – Mulch helps to suppress weed growth, so you can stay clear of chemical herbicides.
  • Temperature regulation – Mulch helps to regulate soil temperature, keeping plants cooler in the summer and warmer in the winter.
  • Soil improvement – As mulch breaks down, it adds organic matter to the soil, improving soil structure and fertility.

How to use mulch

There are a few different types of mulch out there and each comes with its own benefits and unique aesthetic. For example, organic mulches like shredded bark or wood chips are great for retaining moisture, and improving soil fertility because they break down over time. They also create a natural, earthy aesthetic. Opting for straw or hay mulch is excellent for vegetable gardens as it keeps your soil warm, prevents erosion, and adds organic matter. Or alternatively, if you’re looking for a long-lasting option, inorganic mulches such as gravel or stone can be effective in controlling weeds and retaining moisture, although they don’t contribute to soil health like organic options.
