More wintry weather on tap; be ready for frost and rain
In weak February sunlight, a honeybee visits an early bloom on a nectarine tree. Note: If your peach or nectarine tree looks like this, it's too late to spray for peach leaf curl. There's a small window remaining if a tree is not yet showing bud swell. Kathy Morrison
This week, Mother Nature reminds us in often-sunny Sacramento: It’s still winter!
In fact, we’re in store for some of the coldest nights we’ve had in months. “Widespread frost” is forecast by the National Weather Service for the wee hours of Sunday, Monday and Tuesday mornings. The weather service also predicts that there’s a 50-50 chance Sacramento will dip below 32 degrees early Monday or Tuesday.
Make sure to protect sensitive plants and tender seedlings. Succulents may be particularly vulnerable.
By Wednesday night, the threat of frost disappears as a major storm rolls in. The rain and cloud cover will keep nighttime temperatures above freezing – but daytime temperatures won’t be warm. Expect afternoons in the mid to low 50s.
As for that rain, the weather service expects Sacramento will get 1 to 2 inches from this next storm, starting Wednesday. We’re going to stay soggy through Friday, Valentine’s Day.
Be careful walking or working in wet soil; it compacts easily.
* Keep the irrigation turned off; the ground is plenty wet with more rain on the way.
* 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, stock, 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 cauliflower – 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.

Garden Checklist for week of April 20
Before possible showers at the end of the week, take advantage of all this nice sunshine – and get to work!
* Set out tomato, pepper and eggplant transplants.
* 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.
* Plant summer bulbs, such as gladiolus and tuberous begonias.
* Transplant lettuce and cabbage seedlings.
* Smell orange blossoms? Feed citrus trees with a low dose of balanced fertilizer (such as 10-10-10) during bloom to help set fruit. Keep an eye out for ants.
* Apply slow-release fertilizer to the lawn.
* Thoroughly clean debris from the bottom of outdoor ponds or fountains.
* 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.
* Spring brings a flush of rapid growth, and that means your garden is really hungry. Give shrubs and trees a dose of a slow-release fertilizer. Or mulch with a 1-inch layer of compost.
* Start thinning fruit that's formed on apple and stone fruit trees -- you'll get larger fruit at harvest (and avoid limb breakage) if some is thinned now. The UC recommendation is to thin fruit when it is about 3/4 of an inch in diameter. Peaches and nectarines should be thinned to about 6 inches apart; smaller fruit such as plums and pluots can be about 4 inches apart. Apricots can be left at 3 inches apart. Apples and pears should be thinned to one fruit per cluster of flowers, 6 to 8 inches apart.
* Azaleas and camellias looking a little yellow? If leaves are turning yellow between the veins, give them a boost with chelated iron.
* Pinch chrysanthemums back to 12 inches for fall flowers. Cut old stems to the ground.
* Weed, weed, weed! Don’t let unwanted plants go to seed.
