PLEASE NOTE: In the autumn of 1995, we hatched the idea for a free, local gardening publication. The following spring, we published the first issue of Michigan Gardener magazine. Advertisers, readers, and distribution sites embraced our vision. Thus began an exciting journey of helping our local gardening community grow and prosper.
After 27 years, nearly 200 issues published, and millions of copies printed, we have decided it is time to end the publication of our Print Magazine and E-Newsletter.

We will continue to update our Website with articles and enter current gardening events in our website Event Calendar. All the best wishes for 2024 and beyond.

How much mulch is required to cover my garden?

April 29, 2011 •

I want to cover a 12 foot by 25 foot area with 3 inches of mulch. How many yards should I get?

The first thing to decide is how deep you want your mulch, which you have determined to be 3 inches (or 1/4 foot). Then use this formula to calculate the cubic yards: (length x width x depth)/27. For your 12 x 25 foot area: 12 x 25 x .25 = 75. 75/27 = 2.77. So, you need 3 cubic yards. Of course, this formula will work for any material, such as topsoil, compost, mulch, etc.

Need to figure out how much mulch you need for your project? Try out the handy Michigan Gardener soil and much calculator.
