Certain vegetable varieties grow well in cooler weather. Crops planted during summer may be ready between September and October or grown during winter for harvest in early spring. Roots actually get sweeter with chilling, fewer pests are around, and some crops like cilantro and spinach are slower to bolt when planted in August. Use season extenders like Harvest Guard to protect crops from frost.

Fall harvest for crops such as Asian greens, beets, carrots, cilantro, kale, lettuce, peas, and Swiss chard. Crops like corn salad (mache), kale, leeks, Swiss chard, hardy brassicas, and greens (with protection) can survive the cold temperatures of winter, but don’t grow much during the coldest months; they are generally harvested between November and late February.

Overwintering crops are meant to be tiny plants when winter sets in, and while they grow slowly during winter, they are ready to harvest in early spring and can withstand most of winter with mild protection in severe weather. These crops include broccoli, cabbage, cauliflower, collards, and kale. If grown under a cloche or cold-frame, Asian greens, cilantro, corn salad, lettuce, spinach, and Swiss chard can also be grown all winter. When planting, use an organic starter fertilizer low in nitrogen for slow, hardy growth. Use liquid fertilizer/higher nitrogen in spring as plants begin to “wake up.” Continue active slug control during winter months, especially during mild, wet conditions.
