20 Reasons Why You Should Mulch Your Garden

What is Mulch?

Mulch is a material that is spread around a plant or over the soil surface as a protective layer. If you think of soil as a ‘cake,’ the mulch is simply the ‘icing’ or ‘topping’. It provides a huge range of benefits for you and your garden. Mulch comes from a wide variety of organic or inorganic materials. Mulch ranges in cost from free to expensive.

20 Benefits of Using Mulch in Your Garden

Why do you need mulch anyway?  These are some of the reasons to use the ‘marvellous miracle of mulch’ in your garden.

1. Adds organic matter to your soil. This helps make your garden healthier and more resistant to pest and disease. (Saves money on pest control).

2. Provides valuable slow-release nutrients and prevents vitamin loss in plants. (Saves money on fertilisers).

3. Helps retain moisture in the soil for longer. Mulch prevents evaporation by shielding the soil from the sun. It also reduces water run-off during rain or watering. This reduces the amount of water needed. (Saves money).

4. Shades delicate seedlings from too much sun. (A mini umbrella).

5. Reduces time spent watering. (Saves time and money).

7. Provides a natural barrier to stop weeds from growing and competing with plants for nutrients. How? By blocking the sunlight. You’ll find it easier to remove the few weeds that do grow. (Saves you time).
