Summer-like feel to post-Easter weather; remember to water new transplants

Happy Easter! Welcome to tomato planting season!
April continues with more afternoons in the 80s and thoughts of summer harvests. According to the National Weather Service, Sacramento can expect above-average temperatures through Wednesday, peaking at 84 degrees on Tuesday. Average high for this week in Sacramento: 74 degrees.
What's important is that overnight lows will be warm, too, with most nights above 50 degrees. That’s also above average (46 degrees). That combination of warm days and nights speeds soil warming – a major factor in tomato transplant success.
Before you plant ALL your tomatoes and other summer favorites, remember: April weather can quickly change. A weak storm front is expected to pass through Northern California later this week, dropping high temperatures significantly. Friday’s forecast high is 68 with plenty of cloud cover – but only a slight chance of rain (for now). Remember to water new transplants and keep seed beds moist.
Before those possible showers, 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 now forming 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.

Garden Checklist for week of May 18
Get outside early in the morning while temperatures are still cool – and get to work!
* Plant, plant, plant! It’s prime planting season in the Sacramento area. Time to set out those tomato transplants along with peppers and eggplants. Pinch off any flowers on new transplants to make them concentrate on establishing roots instead of setting premature fruit.
* Direct-seed melons, cucumbers, summer squash, corn, radishes, pumpkins and annual herbs such as basil.
* Harvest cabbage, lettuce, peas and green onions.
* In the flower garden, direct-seed sunflowers, cosmos, salvia, zinnias, marigolds, celosia and asters. Transplant seedlings for many of the same flowers.
* Plant dahlia tubers.
* Transplant petunias, marigolds and perennial flowers such as astilbe, columbine, coneflowers, coreopsis, dahlias, rudbeckia and verbena.
* Keep an eye out for slugs, snails, earwigs and aphids that want to dine on tender new growth.
* Feed summer bloomers with a balanced fertilizer.
* For continued bloom, cut off spent flowers on roses as well as other flowering plants.
* Are birds picking your fruit off trees before it’s ripe? Try hanging strips of aluminum foil on tree branches. The shiny, dangling strips help deter birds from making themselves at home.
* As spring-flowering shrubs finish blooming, give them a little pruning to shape them, removing old and dead wood. Lightly trim azaleas, fuchsias and marguerites for bushier plants.
