April showers will give way to plenty of sunshine

Talk about weather whiplash! Two days after afternoons in the 80s, noon Saturday (April 13) in Sacramento was wet and a very chilly 47 degrees.
Our wild weather continues this week. Fast-moving thunderstorms made for a soggy weekend, but that rain won’t stick around. By Tuesday, Sacramento can expect a high of 76 degrees, according to the National Weather Service. Wednesday, Thursday and Friday are all forecast in the low 80s.
Overnight lows are remaining stubbornly chilly, dipping down into the 40s each night. But nights also are starting to edge warmer. By next weekend, we should see lows in the mid 50s, says the weather service.
That’s still not warm enough to transplant tomatoes directly in the ground, but we’re getting there.
After Saturday’s wet weather, soil will be soft and easy to work this week. So, dig in! (Wait a few days, though, to avoid walking on or working soggy soil that could become compacted.)
* April is the last chance to plant citrus trees such as dwarf orange, lemon and kumquat. These trees also look good in landscaping and provide fresh fruit in winter.
* 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.
* Spring brings a flush of rapid growth, and that means your garden is needs nutrients. Give shrubs and trees a slow-release fertilizer. Or mulch with a 1-inch layer of compost.
* Are azaleas and camellias looking a little yellow? If leaves are turning yellow between the veins, give them a boost with chelated iron.
* 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, 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.
* Mid to late April is about the last chance to plant summer bulbs, such as gladiolus and tuberous begonias.
* Transplant lettuce seedlings. Choose varieties that mature quickly such as loose leaf.

Garden Checklist for week of Jan. 12
Once the winds die down, it’s good winter gardening weather with plenty to do:
* 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. (The exceptions are apricot and cherry trees, which are susceptible to a fungus that causes dieback. Save them until summer.) 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.
* After the wind stops, apply horticultural oil to fruit trees to control scale, mites and aphids. Oils need 24 hours of dry weather after application to be effective.
* This is also the time to spray a copper-based fungicide to peach and nectarine trees to fight leaf curl. (The safest effective fungicides available for backyard trees are copper soap -- aka copper octanoate -- or copper ammonium, a fixed copper fungicide. Apply either of these copper products with 1% horticultural oil to increase effectiveness.)
* When forced bulbs sprout, move them to a cool, bright window. Give them a quarter turn each day so the stems will grow straight.
* Browse through seed catalogs and start making plans for spring and summer.
* Divide daylilies, Shasta daisies and other perennials.
* Cut back and divide chrysanthemums.
* Plant bare-root roses, trees and shrubs.
* Transplant pansies, violas, calendulas, English daisies, snapdragons and fairy primroses.
* In the vegetable garden, plant fava beans, head lettuce, mustard, onion sets, radicchio and radishes.
* Plant bare-root asparagus and root divisions of rhubarb.
* In the bulb department, plant callas, anemones, ranunculus and gladioli for bloom from late spring into summer.
* Plant blooming azaleas, camellias and rhododendrons. If you’re shopping for these beautiful landscape plants, you can now find them in full flower at local nurseries.
