Fog, showers and occasional sun; weather-wise, the final days of 2020 will be a mixed bag for Sacramento.

After a healthy soaking on Christmas night, more rain is in the forecast for Sunday night, Monday and Wednesday, according to the National Weather Service. In between, expect mostly patchy ground fog and cloudy skies. The sun will break through Tuesday and Friday, New Year's Day.

Temperature wise, afternoons will mostly be in the low to mid 50s with overnight lows in the 30s (but not quite freezing).

Make the most of those sunny afternoons. There's plenty to do in the winter garden:

* Prune, prune, prune. Now is the time to cut back most deciduous trees and shrubs. The exceptions are spring-flowering shrubs such as lilacs and Japonica camellias .
* It's also the time to prune most fruit trees. (The exceptions are citrus and apricots.) Clean up leaves and debris around the trees to prevent the spread of disease.
* Prune roses, even if they’re still trying to bloom. Strip off any remaining leaves, so the bush will be able to put out new growth in early spring.
* Clean up leaves and debris around your newly pruned roses and shrubs. Put down fresh mulch or bark to keep roots cozy.
* Apply horticultural oil to fruit trees soon after a rain to control scale, mites and aphids. Oils need 24 hours of dry weather after application to be effective.
* This is also the time to spray a copper-based oil to peach and nectarine trees to fight leaf curl.
* Divide daylilies, Shasta daisies and other perennials.
* Cut back and divide chrysanthemums.
* Transplant pansies, violas, calendulas, English daisies, snapdragons and fairy primroses.
* In the vegetable garden, plant fava beans, head lettuce, mustard, onion sets, radicchio and radishes.
* Plant bare-root asparagus and root divisions of rhubarb.
* In the bulb department, plant callas, anemones, ranunculus and gladiolus for bloom from late spring into summer.

Dig In: Garden Checklist

For week of Dec. 3:

Make the most of gaps between raindrops. This is a busy month!

* Windy conditions brought down a lot of leaves. Make sure to rake them away from storm drains.

* Use those leaves as mulch around frost-tender shrubs and new transplants.

* Rake and remove dead leaves and stems from dormant perennials.

* Just because it rained doesn't mean every plant got watered. Give a drink to plants that the rain didn't reach, such as under eves or under evergreen trees. Also, well-watered plants hold up better to frost than thirsty plants.

* Prune non-flowering trees and shrubs while they're dormant.

* Clean and sharpen garden tools before storing for the winter.

* Brighten the holidays with winter bloomers such as poinsettias, amaryllis, calendulas, Iceland poppies, pansies and primroses.

* Keep poinsettias in a sunny, warm location. Water thoroughly. After the holidays, feed your plants monthly so they'll bloom again next December.

* Plant one last round of spring bulbs including daffodils, crocuses, hyacinths, anemones and scillas. Get those tulips out of the refrigerator and into the ground.

* This is also a good time to seed wildflowers such as California poppies.

* Plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.

* Late fall is the best time to plant most trees and shrubs. This gives them plenty of time for root development before spring growth. They also benefit from fall and winter rains.

* Lettuce, cabbage and broccoli also can be planted now.

* Plant garlic and onions.

* Bare-root season begins. Plant bare-root berries, kiwifruit, grapes, artichokes, horseradish and rhubarb. Beware of soggy soil. It can rot bare-root plants.
