The kids, dogs, and gardens post got me thinking. We have a big deck that gets sun, but not much actual dirt that gets any. I tried growing greens and some peas in the strip of dirt that's there, but nothing really did all that great. I did do tomatoes and tried bush cucumbers, also some peppers, in containers and they came out ok. I am really interested in expanding to more stuff in container gardening, but short on details.
I've heard of growing potatoes in garbage bags , any one done this?
How deep do raised boxes need to be for kale and chard if the boxes are placed on a cement deck. How about carrots, beets, etc. Could you do this in a fairly short, box, or does it need to be over 12 inches deep?
Is there a good way to keep the moisture from watering off of the deck surface - tarps, plastic, etc. or will this prevent adequate draining?
Finally, is there a rough estimate of how heavy dirt is? Kind of a silly question, and obviously dependent on how wet the dirt is, but important for figuring out where to put a bigger container. I don't want to break my deck.
The holzer presentation won't cover this, but holzer has done a lot of interesting work in the space of urban permaculture.
Container gardening is something I did a lot of when I lived in the university neighborhood about 15 years ago. Moderately labor intensive. It can be done, and there are a lot of fascinating things in that space.
