Delta breeze brings some relief after epic heat wave
Gardeners probably all feel like this poor navel orange, after more than a week of 100-degree-plus temperatures: Scorched. Kathy Morrison
Relief! The Delta Breeze never felt so good!
Onshore flow of cooler air has finally brought an end to the worse early September heat wave in Sacramento history.
How hot was it? According to the National Weather Service, Downtown Sacramento averaged 108.8 degrees over September’s first nine days, topping the old record for that period (101.1, set in 1923) by 7.7 degrees. Normal for the first two weeks of September: 92.6.
Our overnight lows set a record high, too, averaging 71.1 degrees over the first nine nights in September. This month often is pretty warm at night; the old high-low record was 69.7, set in 1998. Average for this time period: 60. 8.
“It was quite the start to September for #NorCal with a historic heat wave,” tweeted the Sacramento NWS office. “This helped bring the hottest start to the month of September on record for interior Northern California with the average high so far for Sacramento at 108.8 and 109.8 for Redding.”
Sacramento International Airport set daily records with new highs on six consecutive days, Sept. 4-9.
What a difference a little ocean breeze makes! The weather service predicts high temperatures 20 degrees or more cooler than last week. The forecast high for Wednesday: 81 degrees.
Sacramento is expected to stay comfortably in the 80s through next weekend. Instead of heat, the challenge now will be smoke from nearby wildfires. But forecasters anticipate the onshore flow will push most of the haze east, out of Sacramento.
What to do now that you can venture outdoors?
* Start by rinsing off your plants. Sticky residue from smoke can stick to leaves and clog pores, inhibiting their ability to “breathe.” This also will help get rid of spider mites, which have been loving this dry heat.
* Now is the time to plant for fall. Warm soil will get these veggies off to a fast start.
* Keep harvesting tomatoes, peppers, squash, melons and eggplant – if you have any. Wash veggies well to remove smoke residue.
* 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.
* Dig up and divide daylilies as they complete their bloom cycle.

Garden Checklist for week of Nov. 3
November still offers good weather for fall planting:
* If you haven't already, it's time to clean up the remains of summer. Pull faded annuals and vegetables. Prune dead or broken branches from trees.
* Now is the best time to plant most trees and shrubs. This gives them plenty of time for root development before spring growth. They also benefit from fall and winter rains.
* Set out cool-weather annuals such as pansies and snapdragons.
* Lettuce, cabbage and broccoli also can be planted now.
* Plant garlic and onions.
* Keep planting bulbs to spread out your spring bloom. Some possible suggestions: daffodils, crocuses, hyacinths, tulips, anemones and scillas.
* This is also a good time to seed wildflowers and plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.
* Rake and compost leaves, but dispose of any diseased plant material. For example, if peach and nectarine trees showed signs of leaf curl this year, clean up under trees and dispose of those leaves instead of composting.
* Save dry stalks and seedpods from poppies and coneflowers for fall bouquets and holiday decorating.
* For holiday blooms indoors, plant paperwhite narcissus bulbs now. Fill a shallow bowl or dish with 2 inches of rocks or pebbles. Place bulbs in the dish with the root end nestled in the rocks. Add water until it just touches the bottom of the bulbs. Place the dish in a sunny window. Add water as needed.
* Give your azaleas, gardenias and camellias a boost with chelated iron.
* For larger blooms, pinch off some camellia buds.
* Prune non-flowering trees and shrubs while dormant.
* To help prevent leaf curl, apply a copper fungicide spray to peach and nectarine trees after they lose their leaves this month. Leaf curl, which shows up in the spring, is caused by a fungus that winters as spores on the limbs and around the tree in fallen leaves. Sprays are most effective now.
