Gather Spent Annuals
Pull up marigolds, zinnias, celosias, and other warm-season annuals that withered with the first frost. Cultivate the soil if it\'s dry enough, and work in a nice layer of compost or other organic matter. Then add mulch, and the spot is ready for spring planting.
Rake leaves and pine straw that are blocking light to your lawn. Pile the leaves in a shady spot where they can slowly rot into leaf mold. This process usually takes two years, but the result is well worth the wait.
Rest Holiday Cactus
After the last blooms shrivel, move your holiday cactus to a cool room near a north or east window. Reduce watering so that the soil stays slightly moist, and stop feeding the plants altogether. Like most cacti, holiday cactus benefits from a leisurely winter rest.
Finish Planting Bulbs
Time is running out for planting tulips, daffodils, and other spring-flowering bulbs. If you have some bulbs chilling in your refrigerator but have no time to dig planting holes, pot them up instead. Later in winter you can force the potted bulbs to bloom indoors, or carefully transplant them to the garden.
Propagate Winter-Green Perennials
Shasta daisy, myosotis, creeping phlox, and other perennials that don't go completely dormant in winter are what I call winter-green perennials. It's a little late to actually dig and divide them, but you can take up small rosettes and plant them in pots. Set out these little guys first thing in spring.
