'Wet and mild' winter could be ahead

Old Farmer's Almanac predicts rain, warm temperatures for Northern California

A bucketful of rain is a welcome sight -- and we'll be seeing more rain this winter, according to the Old Farmer's Almanac. Kathy Morrison

Happy winter solstice! The shortest day of the year, Wednesday marks the first day of winter and the start of what should be the coldest and wettest season of our gardening year. What can we expect in the months ahead?

According to the Old Farmer’s Almanac, California and much of the west should enjoy a “wet and mild” winter – rainy but relatively warm. Meanwhile, the Midwest and East will be “shivery and snowy.” (Where would you rather garden?)

Now in its 231st year, the Old Farmer’s Almanac has a knack for long-term seasonal forecasts and has been helping farmers – and gardeners – plan ahead for more than two centuries. Its publishers released its winter forecast in November, well before blizzard conditions started barreling across the Central U.S. A bomb cyclone definitely fits that shivery, snowy prediction.

For us Northern Californians, the Almanac foresees “above normal” precipitation coupled with “above average” temperatures. Fortunately, the forecast also predicts above average Sierra snow. But if temperatures drift too high, that snow pack may melt quickly.

Warmer than average temperatures may bring an early spring as trees and shrubs bud out early. Historically, Sacramento averages highs of 54 degrees and lows of 38 degrees in December and January. But too warm of overnight temperatures may have an impact on future fruit production; apples, pears, peaches and many other kinds of fruit need “chill hours” – time under 45 degrees – to successfully set a good crop.

Nothing grows without water and we may finally have a wet winter. The Almanac’s forecast for California predicts a much-needed end to our prolonged drought:

“Winter will be warmer and wetter than normal, with above-normal mountain snows. The coldest temperatures will occur in mid-November, mid-January, and early February. The stormiest periods will be in mid- to late December, early and late January, early and late February, and late March.”

Sacramento’s November was indeed cold, according to the National Weather Service, with the average daily temperature 3.4 degrees below normal. Some days were more than 8 degrees colder than average for those November dates. New record lows (34 degrees) were set on Nov. 21 and 30.

As for the storms, Sacramento has received 4.69 inches of rain so far this December; that’s double our average (2.17 inches) for this month’s first three weeks. And we may add to that December total soon; the National Weather Service sees “widespread precipitation possible” next week.

Garden checklist for week of Aug. 16

During this break in the heat, feed your garden. Make sure to water before and after applying fertilizer.

* In the garden, direct seed beets, carrots, leaf lettuce and turnips.

* Plant potatoes.

* Harvest tomatoes, beans, squash, pepper and eggplants to prompt plants to keep producing. Give your plants a deep watering twice a week, more if planted in containers. Also, give them a boost with phosphate-rich fertilizer to help fruiting.

* Watch out for caterpillars and hornworms in the vegetable garden. They can strip a plant bare in one day. Pick them off plants by hand in early morning or late afternoon.

* Feed citrus trees their last round of fertilizer for the year. This will give a boost to the fruit that’s still small.

* Mulch can be your garden’s best friend – it conserves moisture while blocking out weeds. But don't let mulch mound around stalks, stems or trunks. That can promote rot.

* Camellia leaves looking a little yellow? Give them some chelated iron. That goes for azaleas and gardenias, too.

* Pick up after your fruit trees. Clean up debris and dropped fruit; this cuts down on insects and prevents the spread of brown rot. Then feed fruit trees with slow-release fertilizer for better production for next year.

* To prolong bloom into fall, feed begonias, fuchsias and container plants. Always water before fertilizing.

* Fertilize fall-blooming perennials, too. Chrysanthemums can be fed until the buds start to open.

* Prepare for a fall full of flowers by paying a little extra attention to your garden. Cut off spent blooms from roses, annuals and perennials, then give them a boost of fertilizer. Make sure to water plants before feeding. Roses will rebloom about six to eight weeks after deadheading.

* Indoors, start seedlings for fall vegetable planting, including bunching onion, cabbage, broccoli, cauliflower, kale, radicchio and lettuce.

* Sow seeds of perennials in pots for fall planting including yarrow, coneflower and salvia.
