I had a really bad garden year last year. It was partially due to our 2-week vacation in June, which either left some young plants neglected or caused me to plant things late (and for the weeds to start taking root unchecked). I also had too many "experiments" going on - one of which was letting some clover be a natural, living mulch in one of the beds. Well, turns out I had the wrong kind of clover (red, needs to be white) so it just choked all my peppers out.
Needless to say, next year I am going for simplicity. I already filled one of my three beds with garlic and onions only, so there's an easy crop. I'm going to do my usual tomatoes and peppers, but do a better job mulching and weeding. I was also going to try potatoes (I'm thinkin Yukon Gold) this year since I heard they are easy. Other plants I'll have going are tomatillos, ground cherries, strawberries, and some perennial berry bushes.
I am open to any suggestions for easy to maintain (and well producing!) crops. I am zone 6b.
