Southern California Coastal & Inland Valleys
Sow beets, caraway, carrots, celery, chard, chervil, chives, cilantro (coriander), collards, dill, endive, fennel, garlic, green onions, kale, kohlrabi, leeks, lettuce, mustard, bulb onion sets, flat-leaved parsley, peas, white potatoes, radishes, shallots, spinach, and turnips. Indoors, start eggplants, peppers, and tomatoes as a promise to yourself that warm times are truly coming.
Transplant artichoke and asparagus crowns and rhubarb rhizomes, broccoli, Brussels sprouts, cabbage, cauliflower, celery, horseradish, kale, leeks, lettuce, onions, peas, and spinach. If the soil is still waterlogged, wait to plant. If that's not possible, gently dig the hole, position the plant, and gently gather the soil around the plant's roots. Water just enough to resettle the soil around the roots. This will result in the least compaction of the soil.
Watch for The Right Time to Spray
Apply the last dormant spray NOW. The precise timing of this application is critical -- before the buds swell is too early, and after the blossoms open is too late. The ideal time is when the buds are swollen but don't yet show color. Once the buds open, the damage has already been done.
Sow ageratums, alyssum, asters, baby-blue-eyes, baby's breath, bachelor's buttons (cornflower), calendulas, campanulas (canterbury bells), candytuft, carnations, clarkias (godetia), coreopsis, columbines, coralbells, cosmos, African daisies (gazania), Shasta daisies, delphiniums, dianthus, forget-me-nots, foxgloves, hollyhocks, impatiens, larkspur, linaria, lobelia, lunaria (honesty, money plant, silver dollar plant), lupines, marigolds, morning glories, nasturtiums, nemesia, pansies, petunias, phlox, California and Shirley poppies, salvia, scabiosa (pincushion flower), snapdragons, stocks, strawflowers (helichrysum), sweet peas, sweet william, verbena, violas, and wildflowers.
Plant bulbs for spring and early summer blooms, including achimenes, agapanthus, amaryllis, tuberous begonias, caladiums, calla lilies, canna lilies, colchicums, dahlias, daffodils, daylilies, gladiolus, bearded and Dutch iris, sternbergias, tigridias, and tuberoses. For continuous spring bloom, plant a selection of anemones, ranunculus, and tigridias every two weeks through March.
