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 May 5
Survey your garden after the May 4 rainstorm. Heavy rain and gusty winds can break the neck of large flowers such as roses. Also:
* Keep an eye on new transplants or seedlings; they could take a pounding from the rain.
* Watch out for powdery mildew. Warmth following moist conditions can cause this fungal disease to “bloom,” too. If you see a leaf that looks like it’s dusted with powdered sugar, snip it off.
* After the storm, start setting out tomato transplants, but wait on the peppers and eggplants (they want warmer nights). Pinch off any flowers on new transplants to make them concentrate on establishing roots instead of setting premature fruit.
* Trim dead flowers but not leaves from spring-flowering bulbs such as daffodils and tulips. Those leaves gather energy to create next year's flowers. Also, give the bulbs a fertilizer boost after bloom.
* Pinch chrysanthemums back to 12 inches for fall flowers. Cut old stems to the ground.
* Mulch around plants to conserve moisture and control weeds.
* From seed, plant beans, beets, cantaloupes, carrots, corn, cucumbers, melons, pumpkins, radishes and squash.
* Plant onion sets.
* In the flower garden, plant seeds for asters, cosmos, celosia, marigolds, salvia, sunflowers and zinnias. Transplant petunias, zinnias, geraniums and other summer bloomers.
* Plant perennials and dahlia tubers for summer bloom.
* Don’t wait; plant summer bulbs, such as gladiolus and tuberous begonias.
* Harvest cabbage, lettuce, peas and green onions.
