Bags or bulk for 1,000 square feet?
At 125 bags, bulk is the better buy. Those bags cost around $500 at $4 each and take 8.3 cart loads to get home; 9.26 cubic yards of bulk hardwood mulch runs $278 to $463 plus a delivery fee of $40 to $80, and it arrives in a pile you can wheelbarrow straight to the beds. Bulk is also easier to get in a single color and texture. Bags still make sense if you have no place for a pile or need dyed or rubber mulch, which rarely sells in bulk.
Spreading 1,000 square feet of mulch
- Pull weeds and edge the beds first; mulch over weeds just hides them for a month.
- Keep mulch 2 to 3 inches away from tree trunks and plant stems. A mulch volcano against the trunk rots the bark.
- Water the beds before mulching so the layer seals in moisture instead of blocking it.
- Spread 3 inches on new beds and 1 to 2 inches when refreshing; more than 4 inches starves roots of air.
- 1,000 square feet at 3 inches is about 100 wheelbarrow loads, roughly 11.1 to 18.5 hours of work for one person.
