The best garden mulch

The Dark Art of Mulch

Mulching is one of easiest & most important things you can do for your garden.

 

Why Mulch?

Mulching is like a love blanket. It conditions the soil & creates an environment for the worker bees of your garden to thrive:  worms + microbes + fungi all love moist & dark warm spaces.

Mulching also regulates soil temperature to reduce stress against drought & heavy rain shock.

And mulching helps to supress weeds and seed germination.

 

How to mulch?

A thin layer of mulch doesn’t really do the trick. Whereas a love blanket 15-20cm deep blocks out the light and reduces seed germination, and works wonders.

How often?

The thicker the layer, the less often you need to apply it. And I recommend topping up your mulch once a year, in early spring, to set your garden up for the following year.

What is the best kind of mulch?

Mixed species, shredded mulch is the best. Shredded mulch knits together on banks and is less likely to roll or blow away.

Chunky bark chips roll off the bank; pine by itself leaches nutrients; inorganic stones suck moisture & don’t break down; weed mats & textiles don’t break down, and they don’t create new soil. Weed mats also limit water & air access to the soil, which are both vital for healthy living organisms & plants roots,  and they create a barrier & stop the natural generation of new topsoil from leaf drop etc.

Mulch vs compost

Mulch is not compost. Mulch is like a blanket. Compost is food. It is best to feed your garden with organic fertilisers in early spring, before you add a layer of mulch over the top.

What about the most annoying thing about mulch?

Yes mulch mysteriously appears all over your paths and lawns over night. But that is a good thing! The chaos is caused by birds; and they are hunting worms and small creatures that live in your soil. It means that your soil is alive and doing its job. You can mitigate the mess, by planting your garden below garden eding, adding mowing strips around lawns, and add planted or built up raised garden edging to contain your beautiful garden behind.
