Hold off on tomatoes; they won't be happy outdoors

April can be unpredictable. So far this month, we've seen examples throughout our lives.

Weatherwise, we've bounced from highs flirting with 80 degrees back down to temperatures 10 degrees below normal. Although days have been sunny, nights are still dipping into the low 40s.

In addition, we're getting wet! After Saturday's rain, expect more Sunday and Monday. The National Weather Service issued a thunderstorm alert for the Valley, warning of possible gusty winds, heavy rain, lightning and even hail. Conditions are right that a weak tornado could pop up, too.

So, keep waiting on transplanting your tomatoes. Summer vegetables need warm soil and nights in the 50s before going in the ground.

What should you be doing this week?
* Harvest oranges, lemons and other citrus fruit. The trees want to bloom and need to shed last year's remaining fruit.
* Feed citrus with a low dose of balanced fertilizer during this month’s bloom and fruit set. If leaves look yellow, your tree may need an iron boost. Feed with a chelated iron fertilizer.
* Apply slow-release fertilizer to the lawn.
* Azaleas and camellias looking a little yellow? If leaves are turning yellow between the veins, give them a boost with chelated iron.

Trim the blooms from spent daffodils and other spring-flowering bulbs.

But don't trim the leaves -- let them store up energy for next year's flowers.

* 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.
* From seed, plant beans, beets, cantaloupes, carrots, corn, cucumbers, melons, pumpkins, radishes and squash.
* Plant onion sets.
* Transplant lettuce and cabbage seedlings.
* 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, summer bulbs and dahlia tubers.

Garden Checklist for week of April 27

Once the clouds clear, get to work. Spring growth is in high gear.

* 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. Late April is about the last chance to plant summer bulbs, such as gladiolus and tuberous begonias.

* Transplant lettuce and cabbage seedlings.

* Weed, weed, weed! Don’t let unwanted plants go to seed.

* 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.

* 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.

* 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.

* Mulch around plants to conserve moisture and control weeds.
