I'd like to have a small veggie garden where I can get fresh vegetables for the table, but I don't have much space. What edible plants can be grown successfully in small and medium sized containers?
Just about any can. My mother-in-law uses earth boxes a lot. A little costly, for me, so I use plastic containers or even totes when I can get them on sale. My biggest problem though has been things that grow on the ground in vine form. Stuff like squash, and watermelons. I need to plant them more in the middle of a bigger container, otherwise the stalk seems to break.
Lettuces are the best plants for small containers. Jason is right though that any vegetables can be grown in a small box. I have a tomato plant inside my room. The tomatoes are as little as a cherry, sometimes even smaller.
If you were to ask my cats all plants are edible but jason is correct there, most can if you are willing to keep an eye on them (esp from cats). Sometimes the smaller the area the more dedication one might need to take care of them.
Yeah, I've grown spinach for salads indoors quite a bit. The thing you need to remember if you want to grow indoors though is you really have to supplement lighting. If you don't have an adequate source of light indoors the plants won't grow or will grow very spindly.
As far as growing in a container, I've grown everything from gooseberry bushes to tomatoes. If you do grow in a container you have to make sure to monitor the water usage of the plant and not get it too wet or dry.
