Blackened Sawdust

Blackened Sawdust

Blackened Sawdust is an aged, naturally darkened wood-shaving material from Corbetts Organics. Its fine, partly composted texture makes it a practical carbon-rich material for surface mulching and for balancing green ingredients in a home compost pile.

Use it to give established garden beds, trees, shrubs and landscape areas a tidy organic layer while it gradually breaks down. It is also a useful “brown” ingredient for compost, alongside grass clippings, fresh weeds and other nitrogen-rich garden waste.

Best for:

• Surface mulch around established trees, shrubs and ornamental garden beds
• Organic landscape areas and garden paths
• Adding carbon to compost piles and garden-waste blends
• Refreshing existing mulched areas with a fine, natural finish

How to use: Spread as a surface layer around 25–40mm deep, then water in. Keep mulch clear of plant stems and tree trunks. Because sawdust is a fine, carbon-rich material, avoid digging large quantities directly into active garden soil. For composting, combine it with nitrogen-rich “green” materials and maintain even moisture.

Coverage guide: 1m³ covers approximately 25m² at 40mm depth. Use our volume calculator to work out the right quantity for your project.
