Gardeners are at risk during triple-digit days

Sacramento’s real summer has finally arrived. Triple-digit temperatures will be the norm this week – just in time for the wrap-up of the State Fair.

Expect to see more days in the 100s in August. It’s Sacramento; we should be used to such summer extremes.

But even longtime residents may ignore the dangers of heat exposure. Too much heat can make you sick; it can even kill you.

According to the National Weather Service, more than 200 Americans die each year from heat-related illnesses.

Gardeners are particularly vulnerable. We want to be outside. We have work to do!

Don’t be a heat victim. Follow these tips from the Sacramento County master gardeners:

1. Acclimate yourself. Gradually get into a summer rhythm; a little time in the sun or outdoors, then a break in the shade or inside. Over days or weeks, you can increase your sun and heat exposure (and sweat less).

2. Make use of cool time. Do your most strenuous tasks during the coolest parts of the day (or night). Get chores done in the early morning or evening. (That’s also the best time to water.)

3. Drink plenty of fluids. That means water or electrolyte-packed sports drinks, not coffee and sodas. Plan on at least one quart of water per hour of outdoor activity. Avoid caffeinated beverages; they make you thirstier.

4. Wear sun protection, such as a brimmed hat and light-colored, lightweight, loose-fitting clothing, preferably cotton. Sunscreen is a good idea, too.

5. Find some shade and use it. Frequent breaks out of the sun are important to regulate your body’s temperature. If no shade is readily available, make some with a portable umbrella or shade structure.

6. Know the symptoms of heat-related illness, such as light-headedness, fatigue, dizziness, fainting, cramping and nausea. If you’re feeling any of those symptoms, get out of the sun. Take a break in the shade.

7. If you suspect heat stroke, call 911. When suffering heat stroke, you stop sweating and your body can’t regulate its temperature. It’s serious and needs immediate medical attention.

8. Remember: Tomorrow is another day. It may be cooler. Do that chore in the morning.

Garden Checklist for week of July 21

Your garden needs you!

* Keep your vegetable garden watered, mulched and weeded. Water before 8 a.m. to reduce the chance of fungal infection and to conserve moisture.

* Feed vegetable plants bone meal, rock phosphate or other fertilizers high in phosphate to stimulate more blooms and fruiting. (But wait until daily high temperatures drop out of the 100s.)

* 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.

* 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.

* 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.
