Mulch Types

Bark, wood chips, gravel, straw, compost — each mulch material has different strengths. The right choice depends on where you're using it and what you want it to do.

CHOOSING MULCH

6 Mulch Types Compared

Bark lasts longest. Compost feeds the soil. Straw is cheap but blows away. Rubber never breaks down. Each has trade-offs — here's what suits your garden.

How to Apply Mulch

Getting the depth right, knowing how much to buy, and avoiding common mistakes like mulch volcanoes — proper application makes all the difference.

GET IT RIGHT

Depth, Quantity & Common Mistakes

Apply 8–10 cm deep, keep it away from plant stems, and never pile it against tree trunks. More isn't always better — too thick and roots suffocate.

Where to Mulch

Different plants and areas need different mulching approaches. Vegetables, roses, trees, and flower beds all have specific requirements.

LOCATION GUIDE

Right Mulch, Right Place

Straw for veg beds, bark for borders, acidic mulch for rhododendrons. Match your mulch to your plants and you'll get better growth with less work.

Mulch for Weed Control

A thick layer of mulch is one of the best ways to suppress weeds without chemicals. Here's how to get maximum weed prevention from your mulch.

WEED SUPPRESSION

Block Light, Stop Weeds

8–10 cm of bark mulch blocks 90% of weed seeds from germinating. Add cardboard underneath for near-total suppression in the first year.
