I must be getting dame bramage because I cant come up with what im looking for. Ive done searches already, and it seems theirs a ton of mulch calculators available on the net which is great. Does anyone have a good formula for field use. Just something to give me a close estimate of how much mulch is needed for a 2" and or 3" bed 'x' feet by 'y' feet. Or perhaps a formula for 2" times total sq footage. Just something to use while out giving an estimate.
