Regional wildfire smoke settling over the Treasure Valley does more than reduce air quality for people. A layer of fine ash on foliage blocks light and clogs the pores trees use to breathe, and prolonged smoky conditions can measurably reduce photosynthesis during the peak of the growing season.
Trees already dealing with summer heat and dry soil are working with less energy reserve than usual when smoke events roll through. The combination adds up over the course of a bad wildfire season, particularly for trees that were already stressed going into summer.
A simple rinse with a hose can clear ash buildup from lower branches and foliage within reach, and keeping up with regular watering during smoky stretches helps a tree cope with the reduced light. Watching for slower recovery or thinning canopy after a heavy smoke week is worth doing on any established tree.
Have you noticed haze or ash buildup on plants and trees around your property this summer?
