I've never really done much container gardening. I guess when you have almost 9 acres, it seems weird to be constrained by containers. It always seems a little forced or artificial to me, and I didn't want to bother with it if I didn't have to.
I'll still put some of the bigger crops in the ground - potatoes, corn, tomatoes - and I'll probably skip a few things this year. But after last year's roaring success with carrots in containers, I am getting in deeper. In addition to the carrots, I've added onions, parsnips, spinach, swiss chard, various lettuces, radishes, and dill. I plan to add a bunch of herbs once we get a little farther into the season.
And the beauty of it? I can take my garden with me if we do ever sell this house.
