Here are things that are important to do in a vegetable garden the day before your first frost.
– Pick any warm crop veggies left in the garden: things like peppers, tomatoes, cucumbers, watermelon, zucchini, summer squashes, winter squashes and pumpkins. Since these plants will all be killed by even a light frost, they can be pulled and composted now.
– For a light freeze (28-32 degrees F), its OK to leave most cold weather crops uncovered. To be on the safe side, I cover my lettuce, bok choi, peas and Swiss chard.
– For a hard frost (below 28 degrees F), cover: artichokes, arugula, beets, bok choi, carrots, cauliflower, celery, Chinese cabbage, endive, escarole, lettuce, mache, parsnips, peas, radicchio, spinach and Swiss chard. Bring potted rosemary inside.
– Crops that can withstand hard frost and do not need protection include: broccoli, Brussels sprouts, cabbage, collards, horseradish, kale, kohlrabi, leek, mustard, onions, parsley, radishes and turnips.
