Welcome to winter gardening. In your area you can seed lettuce, cabbage, chard, onions, and garlic under the protection of a hoop frame but the cold soil means these seeds may not sprout for many weeks. For best results you should try and plant seeds in the fall and then just harvest in the winter. There is a book called \"Winter gardening in the Maritime Northwest\" by Binda Coleman that will help you get started. It is sold on Amazon. Keep growing, Marianne Binetti
