Winter gardening is summer planting for winter harvest.
In our mild Coastal climate we can grow some vegetables all winter without protection. You can eat these plants throughout the winter, so they need to be full size by about Halloween. Until Valentines Day, plants grow very slowly and do not re-grow after harvest as they might in the summer. The greatest challenges are rain, low light levels and temperature swings. Many leafy vegetables like lettuce, kale, salad greens, and Asian vegetables are perfectly suited for winter harvests.
