Cubic yards = cubic feet / 27
4
Bags needed = cubic feet / 2 (rounded up, standard 2 cu ft bags)

Pro Mulching Tips

📏

Stick to 2-4 Inches

3 inches is the sweet spot for most beds. Going deeper than 4 inches can suffocate roots and trap too much moisture, inviting disease.

📅

Timing Matters

Apply mulch in mid-to-late spring after the soil has warmed. Fall touch-ups help insulate roots before winter.

🌳

Keep it Off the Trunk

Leave a 3-6 inch gap around tree trunks and shrub bases. "Volcano mulching" traps moisture and causes rot.

💰

Bulk Saves Money

For anything over 3 cubic yards, bulk delivery is significantly cheaper than bagged mulch from the store.
