- Monitor plants regularly, at least every 2 to 5 days during cool-to-cold weather to catch wilting, irrigation, pest, disease, weed, and other problems early.
- Water thoroughly and protect plants with fabric, cardboard, paper, or plastic sheets during periods of overnight frost, especially tender and sensitive vegetables and herbs including basil, chard, corn, and lettuce.
- Maintain or add mulch.
- Harvest thinnings, remaining fall crops, and winter crops including chard and spinach.
- Irrigate variably depending upon rain frequency and volume; turn off irrigation during rainy periods.
- Add nitrogen as recommended in the Nutrient/Amendment/Fertilization Needs/Tip field in the Planting and Maintaining section for each plant.
- Harvest and save seeds from fall-and-winter-bolted vegetables and herbs such as basil, chard, lettuce, and spinach after seed stalks are brown and dry.
- Cut off expired plant stems at ground level after harvest or as plants die, leaving roots in place to feed soil.
- Plan and complete irrigation, seed-starting, transplanting, soil testing, soil amending, and garden projects for late winter and spring.
- Plan for garden protection from winter winds and/or install windbreaks.
