The bottom line: Mother Nature will dictate what you can accomplish. If the weather holds, then by all means, plug away. But if winter-like weather is upon you, prioritize and do what you can.
Continue planting cool-season crops like beets, cauliflower, kale, cabbage, Brussels sprouts, broccoli, chives, celery, onions, parsley, parsnips, peas, radishes, spinach, lettuce, turnips, and Swiss chard.
Protect new seedlings and winter crops from weather extremes with floating row covers, which are made of lightweight polyester that “floats” on plants. Pull out and rake off garden debris; rake leaves out of beds and add to compost pile. Compost anything that is not diseased or infested with insects. Store garden supplies and potions in a dry place. Remove, dismantle, and store stakes and cages that were erected for plant support.
Dig up potatoes and store in a dark place with low humidity, and pick winter squashes and pumpkins before a hard freeze. Keep harvesting fall crops like beets, cabbage, chard, and leeks.
