depending on where you are, check with local resources for boxes, etc. If you're near a poorer, urban area, there are often community groups which strive to teach the urban poor how to garden & raise a portion of their own food – to make gov't subsidies stretch, but also to teach self-sufficiency and nutrition to families. They generally use SFG as a basis and sell garden boxes at a lower cost (typically underwritten by donors, etc.). Be creative and consider all sources when looking for supplies – a Habitat ReStore is also a great place to buy discounted lumber, etc. Best to you!

Someone on a local gardening listserv I'm a part of posted this link today – and I've already plotted out my SFGs for the summer! I love it – it's free and easy to use and the program tells you how many plants per SF section, as well as when to plant, how to plant (and thin), etc.

I hope it helps you figure out the summer garden plans – I'm already looking on Craigslist and other local places where I can pick up more canning jars than I already have stored. I'm planning on putting up a lot in my FS pantry!
