Gardening in Straw Bales

I just read a great book by Joel Karsten, Guide to Growing a Straw Bale Garden. I was able to check out the e-book version from my public library, plus the author has a web site: http://www.strawbalegardens.com. I think the book and the method are completely awesome!

My new veggie garden is definitely going to be using straw bales, and it is going to be on my driveway! Because I don’t have a car, the driveway has just been wasted, south-facing, full-sun space. Straw bale gardens don’t need to be on dirt. And how convenient is it that fall is the best time to get straw bales?

Why is springtime so far away???
