Believe it or not, you can still grow a decent(ish) garden even when you're living in a dinky apartment. Between the upside-down container planter and various 6 to 12 inch pots, I have a little corner of greenery going on my narrow patio/entry area. Behold, not one but two six-inch Italian sweet peppers:
And they haven't even thought about turning red yet, so they could get much larger before that happens.
I am not very happy with the results of the upside-down part of the container planter, though. The upright plants have far outgrown their topsy-turvy counterparts. I don't think the tomato plant has even grown, much less blossomed.
