Here is a picture of the garden boxes I built a couple of summers ago for veggies.
I need to get working on mine. General rule of thumb in this area is to not plant till May, but I think we are done with frost. This will be my 2nd year trying to grow my own veggies, so I am still learning. Had an amazing tomato crop with more than I knew what to do with. I still can't get over how much better a home-grown tomato is vs a store bought. Also had a great crop of green beans and will be doing that again. Had decent luck with kohlrabi. I totally failed at growing broccoli. And surprisingly my zucchini also failed. I thought is was supposed to be easy to grow, but I think it may have just been overpowered by my tomato plants (which were in the same box). Had decent carrots and radishes as well but I didn't thin them out properly so they never got to big.
My biggest challenge, my dogs. My black lab, who loves fruits and veggies, discovered the "magical boxes full of food" about halfway through the summer last year. My mini aussie made the connection that tomatoes look strikingly similar to tennis balls. It was weird because they pretty much ignored the boxes for the most part, but then I think they noticed I kept eating the green beans straight off the vine and made the connection. Going to put up some sort of fence this year. In addition to the stuff I had good luck growing last year I'm going to try some jalapenos. I may also try to dig up the grass in the corner behind my boxes and try some corn back there assuming I get it fenced off. I would love to also start growing my own hops but that is a whole nother level of challenge.
