What exactly is mulch? We look into the types of mulch and the benefits it can bring to your garden. Read on to find out more!

When it comes to your garden beds, mulch is a must if you want to keep your plants looking healthy. Essentially, mulch is a protective barrier put on top of the soil and around your plants. When it comes to picking the type of mulch for your garden, there are a range of varieties to choose from depending on the look you’re after, your budget and what’s best for your plants. Why exactly should you use mulch? From weed control and moisture retention right through to pest control and soil stability, there are a range of benefits to mulching that we’ve explained below.

Control weeds

For a weed to grow, it needs some form of sunlight. You can use mulch as a barrier to cover your soil, stopping any sunlight from getting through and limiting the amount of weeds that sprout. While different types of mulch work better than others, this is generally the rule of thumb.

Retain moisture

Moisture retention is vital if you want to make sure your plants are getting enough water and absorbing nutrients. Organic varieties of mulch like bark and pine absorb water, while non-organic varieties like stones and gravel cover the soil and limit evaporation.

Prevent soil erosion

If you don’t want your soil to wash away every time it rains, then you’re going to want to mulch your garden. Not only does mulch keep in the moisture, but it traps your soil, limiting the impact of falling water and stopping erosion.

Control pests

The natural oils found in certain types of mulch—like cedar bark—can be used to deter any unwanted creepy crawlies. If you want to keep pests out of your garden beds, use more fragrant mulch varieties as these get the best results.


As well as all these functional benefits, a good batch of mulch can turn a tired garden into something more fresh and healthy looking. Each mulch has it’s own unique benefits, so choose carefully. Whether you prefer the smooth river rock or a more natural looking pine bark, it’s up to you!
