Sacramento could see triple digits this week, but relief may be on its way

Suddenly, Sacramento is feeling mighty toasty. We’re experiencing a spring heat wave – and a challenge to our recent transplants.
“Temperatures will warm up this weekend into early next week,” tweeted the Sacramento office of the National Weather Service on Saturday morning. “Valley locations could see 100 degrees as early as Tuesday. Some relief from the heat is expected at the end of next week.”
Windy conditions were expected to cool temperatures into the high 80s or low 90s for Saturday and Sunday. Gusts on Monday could reach 20 to 25 mph, according to the weather service.
When the wind stops, so does that natural air conditioning. Forecasts for Tuesday and Wednesday hover right around triple digits. Average for mid May in Sacramento: 80 degrees.
Meanwhile, overnight lows will stay warm, over 60 degrees; that’s also about 10 degrees above normal. That will make for warm mornings; get your outdoor activities – and watering – done early.
Currently, the weather service predicts a cooldown on Memorial Day weekend with afternoon temperatures back in the 80s. Until then, concentrate on keeping your garden irrigated and comfortable.
* Don’t fertilize this week. High heat can stress new growth.
* Keep an eye out for slugs, snails, earwigs and aphids that want to dine on seedlings, shoots and buds.
* For continued bloom, cut off spent flowers on roses as well as other flowering plants.
* Don’t forget to water. Seedlings need moisture. Deep watering will help build strong roots and healthy plants.
* Are birds picking your fruit from 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.

Oh, sad zinnia! Keep seedlings watered in
this heat to get them established.

* Run the sprinklers early in the day – before 8 a.m. if possible – to conserve water and minimize plant diseases.
* Add mulch to the garden to help keep that precious water from evaporating. Mulch also cuts down on weeds. But don’t let it mound around the stems or trunks of trees or shrubs. Leave about a 6-inch to 1-foot circle to avoid crown rot or other problems.
* Harvest cabbage, lettuce, peas, fava beans and green onions.
* Delay planting any new transplants or seeds until later in the week when temperatures cool down. Keep seed beds evenly moist.
* Direct-seed melons, cucumbers, summer squash, corn, radishes, pumpkins and annual herbs such as basil.
* In the flower garden, direct-seed sunflowers, cosmos, salvia, zinnias, marigolds, celosia and asters.

Garden Checklist for week of May 5
Survey your garden after the May 4 rainstorm. Heavy rain and gusty winds can break the neck of large flowers such as roses. Also:
* Keep an eye on new transplants or seedlings; they could take a pounding from the rain.
* Watch out for powdery mildew. Warmth following moist conditions can cause this fungal disease to “bloom,” too. If you see a leaf that looks like it’s dusted with powdered sugar, snip it off.
* After the storm, start setting out tomato transplants, but wait on the peppers and eggplants (they want warmer nights). Pinch off any flowers on new transplants to make them concentrate on establishing roots instead of setting premature fruit.
* 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, 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.
* Don’t wait; plant summer bulbs, such as gladiolus and tuberous begonias.
* Harvest cabbage, lettuce, peas and green onions.
