Red Flag Warning means be cautious; what Sacramento-area gardeners need to know
With smoke in the air, be sure to wash particulate dust off any produce before consuming it -- including those snack-perfect cherry tomatoes. Kathy Morrison
We’re in the midst of California fire season. If you need any reminders, just go outside.
Hazy skies are due to smoke from six major wildfires burning in Northern California plus more in southern Oregon. The closest blaze is more than 200 miles away, but the smoke is funneling into the Sacramento Valley and floating our way.
And we’re surrounded by potential fire danger. Due to our wet winter, there’s an abundance of plant material throughout our region. Recent triple-digit weather dried annual weeds and grasses tinder-crisp. That’s fuel for hungry wildfire.
“A Red Flag Warning remains in effect through 8 PM today for portions of the Sacramento Valley,” tweeted the NWS Sacramento office on Wednesday morning. “Breezy winds & very dry conditions will create critical fire weather conditions. Be sure to use extra caution if using outdoor equipment and keep vehicles off of dry grass!”
In the afternoon, winds will push some of the haze out of the Sacramento area, but we can’t breathe easier.
“The smoke and haze present across much of the Valley this morning will diminish briefly this afternoon,” says the weather service. “However, we're expecting haze/smoke to return overnight and into Thursday morning.”

Low humidity, gusty winds and plenty of dry fuel can be a recipe for catastrophe. On Wednesday, humidity levels will dip down to 5 to 17% with wind gusts of up to 35 mph, says the weather service.
“Fire safety should be exercised to prevent fires,” it adds. “Always have an emergency plan if a fire starts near you.”
All it takes is a spark. A metal blade of a lawnmower or trimmer against a rock can ignite dry grass. A vehicle parked on dry grass or weeds can start a fire, too. So can a chain dragging from the back of a trailer. Use extra caution.
As for the hazy skies, tomatoes, peppers and other ripening vegetables could be dusted with fine particulate matter. Make sure to wash anything you harvest before eating. (No backyard cherry tomato-munching right off the vine.)
Spider mites love these dry, hazy, dusty conditions. Take out the hose and give your tomato vines and rose bushes a morning shower; that will knock mites off and refresh plants.
So far, there hasn’t been enough smoke in our area to worry about smoke taint, the absorption of smoke flavors through the skin of ripening fruit. But that could be an issue for grape and fruit growers closer to the fires in Trinity, Humboldt and Siskiyou.
As we know from fire seasons past, conditions can change dramatically in a hurry. It’s better to be prepared.

Garden checklist for week of Aug. 2
Get out early in the morning and monitor your garden’s moisture needs. Deep water and add temporary shade structures for plants that are feeling a little burned. In particular, protect developing peppers and eggplant.
* Put off fertilization until this heat passes; plants need to concentrate on hydration instead of growth.
* Harvest tomatoes, beans, squash, pepper and eggplants to prompt plants to keep producing. Give your plants a deep watering twice a week, more if planted in containers.
* Watch out for caterpillars and hornworms in the vegetable garden. They can strip a plant bare in one day. Pick them off plants by hand in early morning or late afternoon.
* Mulch can be your garden’s best friend – it conserves moisture while blocking out weeds. But don’t let mulch mound around stalks, stems or trunks. That can promote rot.
* Pinch off dead flowers from perennials and annuals to lengthen their summer bloom.
* Pick up after your fruit trees. Clean up debris and dropped fruit; this cuts down on insects and prevents the spread of brown rot.
* Prepare for a fall full of flowers by paying a little extra attention to your garden. Cut off spent blooms from roses, annuals and perennials. Roses will rebloom about six to eight weeks after deadheading.
* Indoors, start seedlings for fall vegetable planting, including bunching onion, cabbage, broccoli, cauliflower, kale, radicchio and lettuce.
* Sow seeds of perennials in pots for fall planting including yarrow, coneflower and salvia.
* In the garden, direct seed beets, carrots, leaf lettuce and turnips. Make sure to keep seeds and seedlings consistently moist.
* Plant potatoes.
