Mulches,Mulches, Mulches

Here we are again, talking about mulches when you probably want to hear about something more interesting right? There’s a reason why gardeners keep talking about mulches, and that is, it’s an important part of gardening whether we like it r not.




And, there’s a right way and a wrong way to spread the mulch.

I'm talking with Steve Falcioni from


Mulches are important, especially in areas that are drought affected or are experiencing water restrictions.

The mulch locks in soil moisture and keeps soil cool in warm weather.


Applying mulch can be a bit of a chore, but it's worth it in the long run.

The reverse is true in cold weather, where the mulch acts a sort of blanket and helps retain heat in the soil layer.

Mulch also acts as a barrier to weed seeds and helps with wind erosion.

Over the years the advice as to how much mulch to apply has changed.

Fine mulch shouldn’t be more than 1cm thick, but chunky mulches, can be around 5cm thick.

Remember of course, that organic mulches bring microbial life to your soil, whereas the inorganic, mostly chunky mulches are just a layer of protection.

TIP: Leave some space around the trunk of trees, as it may encourage fungal growth or collar rot if right up against the main trunk.
