December has been good for rain totals -- so far
Keep frost cloths handy but not on tender plants -- such as this lime tree -- during the daytime this week. Clothespins or binder clips can help keep the cloths together at night if you have to use more than one cloth to cover a plant. Kathy Morrison
Turn off the sprinklers! After our recent soaking rain, our irrigation systems can take a break.
How much rain did we get? Enough to get our current water year back on track.
According to the National Weather Service, downtown Sacramento has received 4.69 inches since Dec. 1. (That includes 1.71 inches this past weekend.) Normal through Dec. 12 is 1.27 inches and all of December averages 3.25.
This month’s storms help make up for a bone dry October and barely moist November. So far, Sacramento has received 5.75 inches since Oct. 1, the beginning of our “water year.” Normal to date: 3.98 inches.
That means Sacramento’s rain totals are currently at 144% of normal. Yay!
That’s good news for our reservoirs, too.
“The foothill and valley rains have begun to saturate our very dry soils with resulting runoff beginning to filter into the interior NorCal reservoirs,” tweeted the NWS Sacramento office. “Current water storage at Shasta Lake at 31% of capacity, Oroville 29%, Folsom 28% and New Melones at 25%.”
That Folsom Lake percentage is not as bad as it sounds. It’s 69% of historical average for Dec. 12. Still, there’s room for a lot more.
And it illustrates just how dry we were in 2022, likely still the driest year on record in Sacramento history.
We’ll need many more rainy days to make up for our current water deficits – and right now, none is in the forecast. A ridge of high pressure is keeping our skies clear – and cold.
Instead of an umbrella, keep your frost cloths handy and be ready to protect tender plants.
According to the weather service, Sacramento can expect “widespread frost” and overnight lows right around freezing every night through at least Monday.

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.
