In the above picture you can see one of our first pot gardens.
Those same plants in the first picture eventually became the one's in this picture!
Cucumbers! In the left side of this picture you can see our compost bucket.
Tomato blossoms.
Radishes are good choices for pots.
If you garden in a pot the most important thing to remember is to water regularly. Plants dry out quick since they are exposed to more air than they would be if they were in the ground. Go for plastic pots over terracotta since terracotta pots dry out much faster. You may want to consider a drip irrigation system to help with the watering. Pot gardens just prove that you can garden almost anywhere. I hope you weren't thinking of some other kind of pot garden! We're talkin' veggies here!
