Remember to water; Sacramento could be in midst of record heat wave
Keep an eye on zucchini and other summer squashes in this heat -- they can grow quickly. This variety is "Cube of Butter" summer squash. Kathy Morrison
Scorching: that’s the holiday weekend forecast for most of California – the Sacramento Valley included.
Forecast highs for Saturday range up to 120 degrees in Redding; that makes Sacramento’s 113 sound almost reasonable.
This weekend, Sacramento could tie or even surpass a nearly century-old record. The hottest July day ever recorded in Sacramento was 114 on July 17, 1925. We’re also on track to tie or beat Sacramento’s record for longest heat wave – 11 consecutive triple-digit days. (That was set in July 2009.) If it tops 100 on Friday, July 12, as expected, that makes 12 straight. The “coolest” day this coming week is Monday’s 101.
According to the National Weather Service, Sacramento is locked into hot weather pattern prolonged by warm nights and little breeze. Not only are days more than 10 degrees above normal, but nights are, too.
Winds are supposed to pick up a little midweek. But instead of cooling us off, gusty conditions heighten fire danger – which already is extreme.
Don’t use power equipment outdoors where there’s any danger of sparks, warns the weather service. Don’t park vehicles on dry grass; one stray spark can start a wildfire.
Meanwhile, take care of garden chores early in the morning, concentrating on watering. We’re still in survival mode until this heat wave breaks.
* Keep your vegetable garden watered, mulched and weeded. Water before 8 a.m. to conserve moisture.
* Prevent sunburn; provide temporary shade for tomatoes, peppers, eggplant, melons, squash and other crops with “sensitive” skin.
* Hold off on feeding plants until temperatures cool back down to “normal” range. That means daytime highs in the low to mid 90s.
* Don’t let tomatoes wilt or dry out completely. Give tomatoes a deep watering two to three times a week. Harvest vegetables promptly to encourage plants to produce more.
* Squash especially tends to grow rapidly in hot weather. Keep an eye on zucchini.
* Some weeds thrive in hot weather. Whack them before they go to seed.
* Pinch back chrysanthemums for bushy plants and more flowers in September.
* Harvest tomatoes, squash, peppers and eggplant. Prompt picking will help keep plants producing.
* Remove spent flowers from roses, daylilies and other bloomers as they finish flowering.
* Pinch off blooms from basil so the plant will grow more leaves.
* Cut back lavender after flowering to promote a second bloom.
* One good thing about hot days: Most lawns stop growing when temperatures top 95 degrees. Keep mower blades set on high.
* Once the weather cools down a little, it’s not too late to add a splash of color. Plant petunias, snapdragons, zinnias and marigolds.
* After the heat wave, plant corn, pumpkins, radishes, winter squash and sunflowers. Make sure the seeds stay hydrated.

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.
