I have read some interesting posts on here of how to determine how much mulch you need. I don't really concentrate on mulch, but I'm looking out for a co-worker - we've worked out the money already. Only thing is eye-balling the bed he wants filled it looks like 1 yard isn't going to make it. Would I be better off to get two yards - the area wraps around the front and back corner of his house. It is about 98' long and 3'-6' wide in some areas. I'm sorry fellas but I'm tired and I'd appreciate any pointers. I'm juggling work, mowing and going to school full-time.
