Frequently asked
What depth of mulch should I use?
3 inches is the sweet spot for weed suppression and moisture retention without smothering plant roots. Refresh with 1" annually.
Bulk vs. bagged — which is cheaper?
Bulk wins above ~2 cubic yards. Below that, bagged is more practical even if slightly more expensive per cubic foot. Bulk delivery typically adds $50–$150 per trip.
How much area does a cubic yard cover?
At 3" depth, 1 cubic yard covers about 100 sq ft. Half that depth doubles the coverage.
