Nature and Gardening

I used to have a deck garden in Chicago about 6 years ago. You just need to be careful about draining fluids onto your neighbors. Normal flower pots weren't a problem, but larger pots and raised beds need to have irrigation or something to sit on so they don't leak sludge onto your neighbors deck if that's an issue for you. Otherwise, what you can grow is only limited to your climate and space available. I had a raised bed big enough to grow basil, parsley, cilantro, and spring onions. Then I had 2 very large pots, one with cherry tomatoes and one with mint. I had issues with rats and squirrels stealing stuff from time to time, so I generally kept the size of what I grew pretty small. Might be difficult to grow root veggies or large things like squash, but you never know until you try.
