Dark, cold months are for a whole lot of planting
some folks just can’t stay out of the garden, no matter the season. if it’s not too wet or freezing, there are several vegetables, flowers, trees, shrubs and perennials that can be planted or propagated now.
Or you can stay warm and start your seedlings indoors.
These recommendations come from Sacramento County UC Cooperative Extension master gardeners.
The first day of winter (Tuesday) is the shortest day of the year, sunlight-wise. Traditionally, it’s a great time to plant garlic and onions for harvesting in summer.
Bare-root season begins. Plant bare-root berries, kiwifruit, grapes, artichokes, horseradish and rhubarb. Beware of soggy soil. It can rot bare-root plants.
Vegetables from seed: Outdoors, plant fava beans, mustard and radishes. Indoors, start broccoli, Brussels sprouts, cabbage, cauliflower, collards, kale and lettuce.
Flowers from seed: Plant California and other poppies, cornflower, larkspur and scabiosa. Indoors, start aster, baby’s breath, calendula, coleus and forget-me-nots.
Nurseries in January have a good selection of bare-root fruit trees and other stock such as grapes and berries. Trees planted in January will benefit from the deep watering of winter rain.
Divide daylilies, Shasta daisies and other perennials.
cut back and divide chrysanthemums.
Plant bare-root roses. if the weather is wet and your ground seems saturated, consider planting your garden additions in large black plastic containers. The black plastic will warm up faster than the ground soil and give roots a healthy start. then transplant the new addition root ball and all into the ground in April as the weather warms. This works for bare-root shrubs, too.
Enjoy sunny winter days by planting for bright spring color. Transplant pansies, violas, calendulas, English daisies, snapdragons and fairy primroses.
in the bulb department, plant callas, anemones, ranuculous and gladiolus for blooming from late spring into summer.
Plant blooming azaleas, camellias and rhododendrons. if you’re shopping for these beautiful landscape plants, you can find them in full flower in January at local nurseries.
Vegetables from seed: Outdoors, plant peas, radishes, lettuce and spinach. Indoors, start broccoli, Chinese cabbage, cabbage, cauliflower, collards and kale.
Flowers from seed: Outdoors, plant baby’s breath, calendula, California poppies, cornflower, larkspur and snapdragons. Indoors, start aster, cleome, coleus, forget-me-nots, hollyhock, stock and verbena.
in the vegetable garden, plant Jerusalem artichoke tubers, and strawberry and rhubarb roots. Transplant cabbage and its relatives broccoli, kale and Brussels sprouts as well as lettuce (both loose leaf and head).
Plant artichokes, asparagus and horseradish from root divisions. Plant potatoes from tubers and onions from sets (small bulbs). The onions will sprout quickly and can be used as green onions in March. Annuals will show up in nurseries in February, but wait until the weather warms a bit before planting. instead, set out flowering perennials such as columbine and delphinium.
Plant summer-flowering bulbs, including cannas, calla lilies and gladiolus.
Vegetables from seed: Outdoors, plant beets, chard, lettuce, mustard, peas, radishes and turnips.
Flowers from seed: Outdoors, transplant or direct-seed snapdragon, candytuft, lilies, astilbe, larkspur, Shasta and painted daisies, stocks, bleeding heart and coral bells.
Seed and renovate the lawn. Feed cool-season grasses such as bent, blue, rye and fescue with a slow-release fertilizer. Check the irrigation system and perform maintenance. Make sure sprinkler heads are turned toward the lawn, not the sidewalk.
in the vegetable garden, transplant lettuce and cole family plants, such as cabbage, broccoli, collards and kale.
before the mercury starts inching upward, this is your last chance to plant such annuals as pansies, violas and primroses.
Plant summer bulbs, including gladiolus, tuberous begonias and callas. also plant dahlia tubers.
Shop for perennials. Many varieties are available in local nurseries and at plant events. They can be transplanted in March while the weather remains relatively cool.
Vegetables from seed: Outdoors, plant beets, carrots, chard, celery, fennel, jicama, leaf lettuce, mustard, spinach, radish and turnip. Indoors, start peppers, tomatoes and eggplant.
Flowers from seed: Outdoors, plant aster, celosia, cleome, cosmos, larkspur, nasturtium, nicotiana and snapdragon. Indoors, start four o’clocks, marigold, scabiosa and sunflower.
What’s in season?
Expect to find these crops all winter, except where noted, at farmers markets. or, harvest them from your own garden: artichokes (December), beets, bok choy, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, celery, chard, collards, grapefruit, kale, leek, lemons, lettuce, mandarins (December and January), onions, oranges, persimmons (December), potatoes, radishes, spinach and turnips.
