Rain and frost fill Sacramento’s forecast

Keep your umbrellas and frost cloths handy. Winter has finally arrived.
Rain (albeit light) and frost fill this week’s forecast, according to the National Weather Service. Unlike December’s relatively warm storms, these systems are coming from Alaska – and mighty chilly.
After Saturday’s showers, more rain is expected Tuesday, Wednesday, Thursday and Friday. But these storms will be hit or miss in the valley; as of Saturday (Jan. 6), the weather service predicts a total of only 0.47 inches for downtown Sacramento for the whole week.
Meanwhile, overnight lows are expected to dip into the 30s almost every night. Frost warnings will be in effect for Sunday and Monday mornings. Be prepared and protect plants before the sun goes down.
Saturday’s rain will help protect frost-sensitive plants, too. Moist soil tends to keep the surrounding air (and plant roots) up to five degrees warmer – just enough to avoid damage.
Daytime temperatures will be on the cool side, too. Tuesday will be our warmest afternoon, topping out at 53 degrees, says the weather service.
Concentrate on getting outdoor chores out of the way on Sunday and Monday, then settle in with some indoor gardening activities such as sharpening tools or sorting old seeds.
* Prune, prune, prune. Now is the time to cut back most deciduous trees and shrubs. The exceptions are spring-flowering shrubs such as lilacs.
* Now is the time to prune fruit trees except apricots, cherries or citrus. Clean up leaves and debris around the trees to prevent the spread of disease.
* Prune roses, even if they’re still trying to bloom. Strip off any remaining leaves, so the bush will be able to put out new growth in early spring.
* Clean up leaves and debris around your newly pruned roses and shrubs. Put down fresh mulch or bark to keep roots cozy.
* Don’t apply any horticultural oils this week. It’s too wet. Oils need at least 24 hours of dry weather after application to be effective.
* Browse through seed catalogs and websites and start making plans for spring and summer.
* If bare-root plants arrive via mail, unpack them immediately and soak their roots in water. They can stay that way for several days until ready to plant.
* Don’t transplant bare-root plants into soggy ground; they can rot. Instead, pot them up in containers with potting soil. They’ll develop strong roots and can be put in the ground in March or April.

Garden Checklist for week of Feb. 2
During this stormy week, let the rain soak in while making plans for all the things you’re going to plant soon:
* During rainy weather, turn off the sprinklers. After a good soaking from winter storms, lawns can go at least a week without sprinklers, according to irrigation experts. For an average California home, that week off from watering can save 800 gallons.
* February serves as a wake-up call to gardeners. This month, you can transplant or direct-seed several flowers, including snapdragon, candytuft, lilies, astilbe, larkspur, Shasta and painted daisies, stocks, bleeding heart and coral bells.
* In the vegetable garden, plant Jerusalem artichoke tubers, and strawberry and rhubarb roots.
* Transplant cabbage and its close cousins – broccoli, kale and Brussels sprouts – as well as lettuce (both loose leaf and head).
* Indoors, start peppers, tomatoes and eggplant from seed.
* Plant artichokes, asparagus and horseradish from root divisions.
* Plant potatoes from tubers and onions from sets (small bulbs). The onions will sprout quickly and can be used as green onions in March.
* From seed, plant beets, chard, lettuce, mustard, peas, radishes and turnips.
* Annuals are showing up in nurseries, but wait until the weather warms up a bit before planting. Instead, set out flowering perennials such as columbine and delphinium.
* Plant summer-flowering bulbs including cannas, calla lilies and gladiolus.
