Putting together the vegetable raised bed garden

Question by Mike C: Having trouble getting healthy vegetables in a raised bed?
I have a 4 foot by 12 foot raised bed garden. I put in very good soil I thought. I have good drainage. I planted carrots, cucumbers, canteloupe, green beans and some flowers. The flowers did pretty well but the vegetables never got big at all. The green beans did OK but were tough and kind of tasteless. The bed gets pretty good sun (3/4 of the day) Any help would be appreciated. I hate to give up!
