Some of the lettuce was planted as seeds, and we also planted seedlings from Home Depot. The carrots, spinach, and kale were all planted as seeds. We will cover the lettuce and spinach on the west side with a clear plastic storage container to protect them from freezing on cold nights and to promote germination during the cooler days.
We planted tomato seedlings early this year. Two of the seedlings will be protected from frost by "walls of water," and we will cover the other two tomato plants with a clear plastic storage container on cold nights.
