Mulch Depth: A Practical Planning Guide
Estimate mulch by area and depth, then adjust for slopes, existing material and plant crowns.
Measure bed area
Break irregular beds into simple rectangles or circles and add the areas.
Choose depth by purpose
A thin top-up and a new installation may need very different depths.
Avoid burying stems
Keep mulch away from trunks, crowns and structures where trapped moisture can cause problems.
Plan delivery access
Bulk mulch volume is useful only if it can be moved efficiently to the beds.
Recheck after settling
Organic mulch changes volume over time and may need seasonal top-ups.
