Plant Greens Early for Winter Tolerance
Plants that have developed deep root systems and mature leaves are more tolerant to the cold. When these plants are 3 or 4 inches in size before the first hard frost, they're mature enough to be harvested throughout the fall, winter, and early spring. These will bolt at the first real warmth of early spring, though, so they can't be counted on to provide a crop after that. But by then you'll have made the first spring plantings, so the gap between harvests won't be too long.
Start or reseed lawns. Keep the soil surface moist so seeds germinate and seedling roots get a good start. Feed and water established lawns; continue mowing at 2 inches in height.
Plant Shrubs With Berries
Shrubs with colorful berries in fall and winter can be planted now. They include abelia, barberry, bottlebrush, holly, oleander, pyracantha, quince, and toyon.
Dig In Amendments
Dig in organic soil amendments so they will break down over the winter, enriching the soil for next year's garden.
Mark Their Places
As you clean up dried foliage from bulbs, mark their locations so you don't damage them when digging later in the season.
