Plant late-season vegetables such as peas, broccoli, cauliflower, cabbages, kale, brussels sprouts, leeks, lettuce, radishes, turnips, and onions.
Once your vegetable garden is finished, plant clover, alfalfa, or legumes as a cover crop. These “green manures” can be plowed under in the spring for a natural fertilizer and soil conditioner.
Bring houseplants indoors before the nights get too cool.
Prepare for Christmas color! Place poinsettias and Christmas cactus indoors where they will receive 10 hours of bright light (and 14 hours of total darkness) each day. A Christmas cactus will need a cool spot (50-60 degrees), while poinsettias are OK at 65-72 degrees.
Plant some spring-flowering bulbs in pots to enjoy over the winter. If you intend to force early blooming for the holidays, put your bulbs in the refrigerator now.
