With the high temperatures this summer, it’s vital to take care to protect plants for the long, hot haul.
When soils dry out, plants get stressed and struggle to recover, he explained. So water deeply and regularly. Especially vulnerable are plants put in this year, but all need attention.
“Get water down to where the roots are,” said Weston Miller, a horticulturist with Oregon State University’s Extension Service. “After watering, dig a small hole to see how far the water has penetrated.”
Irrigate for 45 minutes and then measure. For trees and shrubs, look for water to penetrate the soil to at least eight to 10 inches. For perennials, annuals and vegetables, shoot for moisture to reach 6-8 inches depth.
Soaker hoses or drip systems are best for irrigating because they are more efficient at delivering water and cut down on evaporation, Miller said. As a last resort, use an overhead sprinkler to cover a lot of space. If possible, don’t water in the middle of the day as it will speed up evaporation and can burn foliage on particularly hot days.
While you’re out taking care of your plants, he said, don’t forget to take care of yourself, too. Avoid working in the garden during the hottest part of the day, wear a hat, drink plenty of liquids and use sunscreen.
Miller offers these tips to take care of the garden in hot weather
Check irrigation systems, including soaker hoses and drip systems, for leaks so water doesn’t flood one area and miss another.
Move potted plants and hanging baskets into the shade and check often for dryness. They may need to be watered at least twice a day.
Use shade netting (available at garden centers) to protect plants on especially hot days. In a pinch, use old sheets or curtains. Prop netting or cloth on PVC pipe, stakes or heavy-gauge wire molded over plants.
