Relief from triple-digit temperatures coming this weekend, but smoky skies may linger

Sacramento’s forecast high for Saturday (July 27): 82 degrees. That’s 20 degrees cooler than last weekend – and most of this month.
So far, July is trending to be one of the hottest months on record – not just in Sacramento, but worldwide. Monday (July 22) went down as the hottest day in recorded human history, European climatologists reported this week.https://apnews.com/article/hottest-day-ever-climate-change-weather-heat-extreme-global-warming-8e2b0b7fa0360ecb931ca333a832c694
Sacramento has been doing its part. Through July 25, Sacramento highs have averaged 101 degrees – that’s more than eight degrees above normal (92.6) for July. Helping hold in that heat were unusually warm nights; lows averaged 65 degrees, about six degrees above normal.
This intense heat dried vegetation to a crisp, especially grasses; that’s created high fire danger throughout Northern California. With abundant fuel, the Park Fire in Butte County doubled in size in less than 24 hours, growing to more than 164,000 acres – an area larger than the city of Chicago.
Smoke from that blaze is drifting across the valley and foothills, dropping ash and polluting air. That can trigger breathing problems for people with sensitivities as well as burn eyes.
All this heat and smoke can have major effects on our summer gardens, too. Expect to see some ozone damage to foliage. Smoky skies tend to cut down on bee activity, too. Tomatoes and grapes may develop smoke taint to their flavor. Make sure to wash fruit and vegetables well before eating; soot and ash can cling to their skin or leaves.
With such high fire danger, just a spark can start a catastrophe, warns the weather service. Do not use power equipment outdoors; a lawn mower or edger hitting a rock may be all it takes to cause a blaze. Likewise, don’t park vehicles on dry grass; igniting an engine also can ignite a grass fire.
Cooler conditions starting Saturday will help relieve that fire danger. In fact, the weather service predicts no more triple-digit temperatures for the rest of July – and August starts Thursday.

Garden checklist for week of July 12
Get out early in the morning to take care of garden chores. Temperatures are expected to stay below 80 degrees before 10 a.m.
* Remember to water early and deep; your garden depends on you.
* It’s not too late to add a splash of color. Plant petunias, snapdragons, zinnias and marigolds.
* From seed, plant corn, pumpkins, radishes, winter squash and sunflowers.
* Keep your vegetable garden watered, mulched and weeded. Water before 8 a.m. to reduce the chance of fungal infection and to conserve moisture.
* Water before fertilizing vegetables and blooming annuals, perennials and shrubs to give them a boost. Feeding flowering plants every other week will extend their bloom.
* Feed vegetable plants bone meal or other fertilizers high in phosphate to stimulate more blooms and fruiting.
* 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.
* If your melons and squash aren’t setting fruit, give the bees a hand. With a small, soft paintbrush, gather some pollen from male flowers, then brush it inside the female flowers, which have a tiny swelling at the base of their petals. (That's the embryo melon or squash.) Within days, that little swelling should start growing.
* Pinch back chrysanthemums for bushy plants and more flowers in September.
* 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.
