Here in the Pacific Northwest we’re having a devilish heat wave…and to protect your trees from very hot days there are a few precautions to take.
The most important precaution is to step up your watering. If you’ve been watering once a day at 80 F, you will want to step that up to two or three times a day at 100 + F. When I say ‘water’ I really mean ‘check.’ You might not actually water each plant, but five hours of intense heat and sun can dry out a pot in record time and so we check frequently.
The next precaution might be to put up shade cloth areas that will reduce the local heat by five degrees or so. This step can be significant, particularly for small pots or sun-tender plants.
Another precaution is misting. A hose does this just fine, spray the foliage and benches and gravel down with water. No need to soak the pots, this is just a refresher for the foliage and to cool down the pots a bit.
Finally—and this can make a huge difference—try to relocate trees and companion plants to shadier parts of the yard. This may be a tall tree or even a tall wall that protects an area from afternoon sun.
And cool yourself down with lots of watermelon…
