Check out what our friends over at The Kersten Haus are doing. Their most recent post touches on raised garden beds, composting, and rain barrels. Fun! Kudos, you two.
Rob and I look forward to having our own garden one day. Currently what I plant on our shaded apartment balcony doesn't always seem to do that great. I may try setting some things out front by our apartment door, but not sure how well that will work. I had at one point brought some plants inside, but our cats like to destroy things. Currently we have one little living plant on a window ledge that the cats cannot reach. Tell me your tips and stories.
Edit 4/27/12: Just found this relevant link that I think fellow apartment dwellers will appreciate.
