This was Gerdt's idea: to till up a big piece of our back yard and plant a garden. We have a nice neighbor who owns a roto-tiller, so in exchange for a little babysitting his girls that I did, our neighbor tilled up a piece of ground about 30 feet by about 50 feet (I just went out in the rain and measured).
This has been a lot of fun for the kids to work on with their dad, especially Jordan. They have already planted peas, spinach, and radishes. We will still plant broccoli, cauliflower, squash, peppers, and tomatoes, and maybe more.
