Miracle gro garden soil is about $8 for a 2cf bag. That is going to be about 19 bags.

You can usually buy bags of compost or composted manure fairly inexpensive. I would probably just get about 15 bags of the MG garden soil and mix in enough of the compost to make up the difference.

A truckload of that much soil would probably run you well under $50. I would see if you can find a place that would deliver.

For a raised bed, I would stick with more soil based solutions. Don't dump in a bunch of peat or other mixes based on peat.

Hi esox - what is a "bag of compost"? BlackCow?

Hi: It can be manure based or not. Most big box stores sell it and it usually is pretty inexpensive.

There's no way in hell I would ever fill a raised bed with bagged soil. Way too expensive! If you really want to save money, you got to go bulk.

I'd rent a pickup or borrow a friend's. I can get a yard of topsoil for less than $20 and a yard of compost for less than $25. In your case, I'd get a a HALF yard of each and then add some coarse perlite and peat(at home depot 2 c.f. bags for about $20 for the perlite and $11-12 for a 3 c.f. bag of peat moss). My soil supplier actually has a raised bed mix that they sell for about $40-50/yard. I prefer to make my own.
