Decide Whether to Build a Raised Bed or Use Existing Ground

You're setting up a growing space and weighing the cost of raised beds against just digging into what you've got. This works through your soil type and budget: when raised beds earn their keep, when existing ground is fine, and where the money actually goes. You spend on the right thing rather than the trendy thing.
