Spring? I still have 3-4' of snow on the ground, it snowed over an inch last night and it is still snowing....And to those people in the Great Lakes and New England areas, stay warm!
I would build a little deeper boxes for root veggies--I think 16-18". I usually grow stubby carrots and other than potatoes, the other root veggies are not that large. I always put potatoes in large tubs with plenty of depth. Other veggies will do fine in 12" deep boxes. I don't think that 2 4 x 2 beds will be nearly large enough for 2 people though. I have a 4 x 8 and 2 4 x 4 raised beds that I have no trouble filling. The length of my yard also has a retaining wall where I have a strawberry area. That alone is about 4 x 12. I grow lots of greens as I love to be able to go out in the yard and "pick a salad".
I generally plant lots of greens (all kinds), radishes, carrots, potatoes, broccoli, tomatoes, peppers, cucumbers, and 1 (only 1) zucchini plant.
Psst, Rosebud, I also call them "old lady beds". I have a friend that has an artificial knee and she is not able to get down on her hands and knees at all. She also had no real good place to build permanent beds. So, we made a portable garden. I whipped up some liners made out of landscape cloth and put them into milk crates. These we set on other milk crates to raise them up so they were easy to work on. This made a fast easy garden for her. We ran it much like a square foot garden.
