Organic mulches
Bark, wood fibre, leaf mould and composted materials gradually change and may contribute organic matter. Their appearance and volume change over time.
Mineral mulches
Gravel and stone persist longer but are heavier and influence heat around plants. Landscape fabric does not replace correct soil preparation.
Choose for the site
Consider plant type, slope, wind, pets, drainage and future maintenance before selecting by appearance alone.
Practical checklist
- Compare products by usable volume, not only bag price.
- Confirm material suitability around edible crops.
