Hi there,
I'm an SFG guy. I started with a 4x4 box last summer and I've since added an 8x4 and now about to put in another 4x4. I'm currently growing chives, lettuce, broccoli, mint, red onions, yellow onions, peppers, eggplant, cherry tomatoes, basil, strawberries, spinach, peas, a couple of bean varieties, chard, and okra. People's eyes always get big when I list all my plants - they must think I've got rows stretching across my yard when really I am using an area of only 48 sq. ft. This has been a great gardening experience for me and while I'm now branching out in other ways (fruit trees, permaculture) I have found this method to be an invaluable foundation for getting started.
You can go to Mel's web site (www.squarefootgardening.com) and see pictures from SFGs as well as youtube videos with him.
Keep in mind that SFG is but one method in a whole family of intensive, raised-bed techniques (i.e., "lasagna" method, sheet mulching). After further reading I modified SFG for my big bed (and gave myself more work, granted) by turning over the grass where the bed would go and putting down newspaper instead of weed cloth. That way, earthworms can make their way up into my soil mix and, as the newspaper biodegrades, I can grow root crops without having to build a taller box.
So, from my experience, let me say it's totally worth it to start with SFG, but once you really get into gardening, expand your reading and your range of practice. Well, unless you're in an apartment or other situation with no soil to work with. In that case, maybe the only area to expand your knowledge would be into self-watering containers...

















I know there are some gardening threads on here, but has anyone posted material for urban gardening? Those of us with limited resources, time, space and funds - could use info on said topic. I know there is a great selection of books on it, one 'Square Foot Gardening' by Bartholomew

looks great, talks about easy and simple ways to grow food. If anyone else has some info, videos, etc - fele free to share!
Thanks!
