Question 1

How deep should mulch be?

Accepted Answer

The ideal mulch depth is 2-4 inches. Use 2 inches for decorative purposes, 3 inches for weed suppression and moisture retention, and 4 inches for areas prone to weeds or with poor soil. Avoid exceeding 4 inches as it can suffocate plant roots.

Question 2

Is bulk or bagged mulch cheaper?

Accepted Answer

Bulk mulch is almost always cheaper. Bulk typically costs $25-50 per cubic yard, while bagged mulch at $4-6 per 2 ft³ bag works out to $54-81 per cubic yard. Bulk is cost-effective for anything over 3 cubic yards.

Question 3

How many bags of mulch are in a cubic yard?

Accepted Answer

One cubic yard equals 27 cubic feet. That is about 13.5 bags of 2 ft³ mulch or 9 bags of 3 ft³ mulch. For large projects, bulk delivery is significantly more economical.

Question 4

How often should mulch be replaced?

Accepted Answer

Organic mulch should be refreshed annually. Hardwood mulch lasts 1-2 years, while cedar and cypress can last 2-3 years. Rubber and stone mulch are permanent but may need periodic topping off.
