The solution is a box, to make it possible to have 12" of Mel's Mix! See?

We've planted carrots, onions and potatoes here... it'll be interesting to see how they turn out.
As an aside for our boxes next year, we want to make a single large box with dividers for each square; the overlap of the double width is throwing things off a little. Live and learn, and remember better for next year!
Check out our sprouts! Those are our radishes on the left, and peas and cukes have joined the party since my last update!
