Sunny but BRRRRrrrr....with mornings this cold its good to have cold weather plants that have survived the winter. Beside me are 5 ft rainbow kale bushes as i hold up ice from watering buckets. Perpetual spinach, purple carrots, chard, and Romanesco broccoli are all bi-annuals that flower the second year and winter survivors. These cold mornings will seriously mess up any warm weather plants not covered up. Also cold frames will have such an extreme change in temperature. This is just a tricky time of the spring where it is too easy to think it safe.....be a ware, the world has enough lerts.
