I've had no luck with container gardening til last year...Now it's part of the way to go because I had a hard time getting out back to pick and water plants. I can do it now but I fell in love with the half barrels I put jalapeno's in one sweet Italian peppers for frying in an other, one has gladiolas another tomatoes a black krim, trees you name it my s-i-l has potted it, Calif poppies, strawberries, a blackberry, , plus all types of fruit trees. but out back there is corn, grapes,cucumber, melons but I love the half wine barrels best...I think you will love container gardening, Katie. We're surrounded on 3 sides here by timber, so I have to run around and find the sunniest places, or be content with hostas and ferns! Been using containers for years, and the yields can be really good, especially for bush beans, toms, peppers, and cukes for us.
