Sow last Veggie Seeds
Sow or transplant fava beans, beets, broccoli, Brussels sprouts, cabbage, chard, coriander (cilantro), garlic, kale, kohlrabi, leeks, lettuce (especially romaine types and small-heading bibb and buttercrunch types, which thrive with only minimal damage from light frosts), mustards, green and bulb onions, parsley (the flat-leaf type is hardier than the curly one), peas, radishes, shallots and spinaches, especially the curly-leafed savoy types.
Fruit Tree Dormant Spray Timing
Plan your dormant fruit tree spraying schedule to coincide approximately with cool-weather holidays -- Thanksgiving, New Year's Day, and Valentine's Day. Specific cues are the fall of the last leaf (Thanksgiving), the height of dormancy (New Year's Day), and bud swell (Valentine's Day). Spraying at the precise period of bud swell is especially important -- before the buds swell is too early, and after the blossoms open is too late.
Plant Garlic, Shallots, and Bulb Onions
Plant garlic, shallots, and bulb onions where they won't get water next May and June. You want them to be able to thoroughly dry out and mature before harvesting them in late June and July.
Cover Crops for Home Gardens
Sow winter cover crops -- including fava beans, clovers, peas, annual rye, and vetch to be turned under in the spring as "green manure." When winter's gloom has settled in, it's nice to see something green besides weeds growing, especially when it'll also fertilize the garden in the spring. And you don't have to have a large garden to grow a cover crop -- just consider it a lawn that doesn't need mowing.
Colorful Cabbages and Kale
Plant colorful ornamental cabbage and kale for vibrantly rich reds, blues, and purples to accentuate other garden colors all winter long.
