I'm looking for cheap, free, and biodegradable. I want to sow some flats of lettuce and things like arugula and cress. Not sure how those do here, and not sure the raccoons wont destroy them.
But I thought of box tops. Surely I can find plenty of those somewhere! They might be just perfect...and free! If they decompose, they can go with the other broken down boxes I use as a weed barrier in the mint patch (all the garden I have right now).
Just an idea, but I think it would be an easy one to test!
I'll keep ya posted...we'll see if it works. So far, no raised beds, and I'm shorter on time since starting this Get-Out-Of-Debt-Faster job.
