Question 1

How much mulch do I need?

Accepted Answer

Multiply length × width × depth (in feet) and divide by 27 for cubic yards. A 2-3 inch layer is standard for landscaping beds. One cubic yard covers about 100-162 square feet at 2-3 inches deep.

Question 2

How many bags of mulch per cubic yard?

Accepted Answer

Most mulch bags are 2 cubic feet each. You need 13.5 bags to fill one cubic yard (27 ÷ 2 = 13.5). Round up to 14 bags.

Question 3

How deep should mulch be?

Accepted Answer

Apply 2–3 inches of mulch for established beds. Never exceed 4 inches — too-deep mulch creates anaerobic conditions that suffocate plant roots and harbor pests.

Question 4

How much does a cubic yard of mulch cost?

Accepted Answer

Bulk mulch from a landscape supplier costs $25–$50 per cubic yard depending on type. Bagged mulch (2 cu ft bags) costs $3–$7 per bag at Home Depot or Lowes.

Question 5

Is bulk mulch cheaper than bagged mulch?

Accepted Answer

Yes, significantly. Bulk mulch typically costs $25–$50/yd³ vs. $45–$95/yd³ for bagged (at $3.50–$7 per 2 cu ft bag). Once you need more than 4-5 cubic yards, bulk delivery usually wins.

Question 6

What is the best mulch for vegetable gardens?

Accepted Answer

Straw, shredded leaves, or untreated grass clippings are best for vegetable gardens. Avoid dyed mulches near food plants. Wood chip mulch is great for pathways between beds.

Question 7

How often should I replace mulch?

Accepted Answer

Most wood mulches break down over 1–3 years. Top dress annually with 1 inch of fresh mulch rather than fully replacing. Remove old mulch that has become compacted or developed mold.

Question 8

How do I prevent mulch from washing away?

Accepted Answer

Install metal or plastic edging to contain the mulch. Use chunky wood bark on slopes — it grips better than fine shredded mulch. Avoid applying within 2–4 inches of plant stems.
