Sacramento Digs Gardening: Dig In: Garden checklist for week of Dec. 16

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 Nov. 3

November still offers good weather for fall planting:

* If you haven't already, it's time to clean up the remains of summer. Pull faded annuals and vegetables. Prune dead or broken branches from trees.

* Now 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.

* Set out cool-weather annuals such as pansies and snapdragons.

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

* Plant garlic and onions.

* Keep planting bulbs to spread out your spring bloom. Some possible suggestions: daffodils, crocuses, hyacinths, tulips, anemones and scillas.

* This is also a good time to seed wildflowers and plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.

* Rake and compost leaves, but dispose of any diseased plant material. For example, if peach and nectarine trees showed signs of leaf curl this year, clean up under trees and dispose of those leaves instead of composting.

* Save dry stalks and seedpods from poppies and coneflowers for fall bouquets and holiday decorating.

* For holiday blooms indoors, plant paperwhite narcissus bulbs now. Fill a shallow bowl or dish with 2 inches of rocks or pebbles. Place bulbs in the dish with the root end nestled in the rocks. Add water until it just touches the bottom of the bulbs. Place the dish in a sunny window. Add water as needed.

* Give your azaleas, gardenias and camellias a boost with chelated iron.

* For larger blooms, pinch off some camellia buds.

* Prune non-flowering trees and shrubs while dormant.

* To help prevent leaf curl, apply a copper fungicide spray to peach and nectarine trees after they lose their leaves this month. Leaf curl, which shows up in the spring, is caused by a fungus that winters as spores on the limbs and around the tree in fallen leaves. Sprays are most effective now.
