December starts with damp days but good planting conditions
If you've grown California poppies before, you likely have volunteer plants sprouting already. If not, there's still time to plant seeds of our state flower for blooms next year. Kathy Morrison
Just like last year, December starts wet. But instead of an atmospheric river, we’ve got a week full of drizzle. Keep your umbrella handy, but don’t expect a lot of rain.
Saturday’s showers were just a taste of what’s to come the next six days in Sacramento. According to the National Weather Service, more showers are expected Sunday, Wednesday, Thursday and Friday with foggy conditions in between.
But our rain totals will remain modest – less than 0.2 inches for the whole week. That compares to 2.33 inches for the first five days of December 2022.
All that cloud cover will keep the weather comparatively warm, with highs in the low to mid 60s and overnight lows in the high 40s. Those moderate temperatures will help new transplants, which will appreciate the damp soil, too.
Typically, December is among the rainiest months in Sacramento, averaging 3.25 inches. Temperature-wise, December averages highs of 54 and lows of 38.
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.

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.
