Hey all! I am brand new to the business and to this web site. I have a ton of questions for all you experts. But for now I want to ask this one. I need about 4.5 yards of mulch. I want to buy bags of mulch instead of bulk. So I want to know how many bags of mulch do I need and how do i figure this out. I plan on doing alot of mulching so i could use all the info i can get...Thanks in advance.
