Colder weather cues dormancy -- and pruning time

After such a warm fall, the weather in these final days before winter may seem chilly and dank, but it's actually normal for December in Sacramento. This month averages 56-degree days and 38-degree nights, right around what we've been seeing.

These colder temperatures cue deciduous trees and shrubs to start thinking about taking a long nap. If they haven't already dropped their leaves, they will -- very soon.

That dormancy cues a round of early winter chores. Here's what to do in between storms:

* Prune non-flowering trees and shrubs while they're dormant.
* Prune deciduous fruit trees except apricots (they're pruned in August). Remove and dispose of any "mummy fruit" that clings to the branches; it's full of fungal disease.
* Spray peaches and nectarine trees with copper fungicide spray to prevent leaf curl. This treatment also helps fight brown rot and fire blight. It needs at least 24 hours of dry weather after spraying to be effective.
* Clean and sharpen garden tools before storing for the winter.
* Expecting company? Brighten the holiday garden with winter bloomers such as calendulas, Iceland poppies, pansies and primroses. They'll add instant color and instant cheer.
* It's not too late to transplant trees, shrubs and perennials.
* Transplant lettuce, cabbage, chard, peas and greens.
* Plant from seed radishes, beets, leaf lettuce, greens, peas and fava beans.
* Friday is the first day of winter. That's also the shortest day of the year, the traditional time to plant garlic and onions for harvest in summer.
* Plant bare-root berries, kiwifruit, grapes, artichokes, horseradish and rhubarb. But beware of soggy soil. It can rot bare-root plants.

Garden Checklist for week of Feb. 9

Be careful walking or working in wet soil; it compacts easily.

* Keep the irrigation turned off; the ground is plenty wet with more rain on the way.

* February serves as a wake-up call to gardeners. This month, you can transplant or direct-seed several flowers, including snapdragon, candytuft, lilies, astilbe, larkspur, Shasta and painted daisies, stocks, bleeding heart and coral bells.

* In the vegetable garden, plant Jerusalem artichoke tubers, and strawberry and rhubarb roots.

* Transplant cabbage and its close cousins – broccoli, kale and cauliflower – as well as lettuce (both loose leaf and head).

* Indoors, start peppers, tomatoes and eggplant from seed.

* 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.

* From seed, plant beets, chard, lettuce, mustard, peas, radishes and turnips.

* Annuals are showing up in nurseries, but wait until the weather warms up a bit before planting. Instead, set out flowering perennials such as columbine and delphinium.

* Plant summer-flowering bulbs including cannas, calla lilies and gladiolus.
