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.

Dig In: Garden Checklist

For week of Sept. 24:

This week our weather will be just right for fall gardening. What are you waiting for?

* Now is the time to plant for fall. The warm soil will get these veggies off to a fast start.

* Keep harvesting tomatoes, peppers, squash, melons and eggplant. Tomatoes may ripen faster off the vine and sitting on the kitchen counter.

* Compost annuals and vegetable crops that have finished producing.

* Cultivate and add compost to the soil to replenish its nutrients for fall and winter vegetables and flowers.

* Fertilize deciduous fruit trees.

* Plant onions, lettuce, peas, radishes, turnips, beets, carrots, bok choy, spinach and potatoes directly into the vegetable beds.

* Transplant cabbage, broccoli, kale, Brussels sprouts and cauliflower as well as lettuce seedlings.

* Sow seeds of California poppies, clarkia and African daisies.

* Transplant cool-weather annuals such as pansies, violas, fairy primroses, calendulas, stocks and snapdragons.

* Divide and replant bulbs, rhizomes and perennials. That includes bearded iris; if they haven’t bloomed in three years, it’s time to dig them up and divide their rhizomes.

* Dig up and divide daylilies as they complete their bloom cycle.

* Divide and transplant peonies that have become overcrowded. Replant with “eyes” about an inch below the soil surface.

* Late September is ideal for sowing a new lawn or re-seeding bare spots.
