Frequently Asked Questions
How deep should mulch be?
2–4 inches is typical. Thinner layers don't suppress weeds well; too thick can block water and air from reaching roots.
Bulk or bags — which is cheaper?
Bulk is usually cheaper for larger areas; bags are more convenient for small beds and easier to transport.
Does mulch settle over time?
Yes, it compacts and breaks down. Ordering a little extra lets you top up as it settles.
