Not sure if this is the proper board to place this so if it isn't please forgive
What are some known ways to grow as much produce in as little area as possible? I know about
this way of growing potatoes but what about other plants?
The ways I've heard of so far include:
* Growing tomatoes in an "upside down" planter
* Growing potatoes as mentioned above
* Growing cucumbers/vine beans up a trellis
What about things like watermelon, corn, herbs in general, yellow squash, zucchini etc? I ask because I'd love to know of others experiences with growing produce in small spaces.
