  • Wildfire season has begun in many places around the world.
  • 2
  • The dangerous smoke wildfires produce can spread far and wide.
  • 3
  • It blocks sunlight, poisons the air, and damages health of people and other living things.
  • 4
  • Some of those living things could be the plants in your garden, says gardening expert Jessica Damiano.
  • 5
  • She writes gardening stories for the Associated Press.
  • 6
  • Damiano lives in New York City and recently experienced several days of very smoky air. Wildfires in eastern Canada were the source.
  • 7
  • Damiano, like other people, limited the time she spent outdoors when the air quality was poor.
  • 8
  • She also wore a face covering, or mask, when she had to go outside.
  • 9
  • But the plants in her garden had no such escape.
  • 10
  • They had to breathe the poisoned air through the extremely small pores in their leaves.
  • 11
  • Brooke Edmunds is a plant scientist and community horticulturalist with Oregon State University Extension.
  • 12
  • She said plants subjected to smoke for a short amount of time will usually "bounce back," or recover quickly.
  • 13
  • "It depends on how close you are," she said.
  • 14
  • "There could also be a localized effect, where one garden is covered in ash, and a half-mile away, there's nothing because that's the way the wind was moving things around."
  • 15
  • Pollutants and small particulate matter landing on your plants can block sunlight, which is essential for photosynthesis.
  • 16
  • Reduced photosynthesis results in reduced energy.
  • 17
  • That means slower growth.
  • 18
  • Additionally, with longer exposure, organic compounds found in smoke can interfere with a plant's ability to take in nutrients.
  • 19
  • Any damage will not be noticeable right away.
  • 20
  • The best thing home gardeners can do is "keep an eye on plants," Edmunds advises.
  • 21
  • She suggests giving your plants some extra love and care for the entire season after exposure.
  • 22
  • "Most will pull through," Edmunds added.
  • 23
  • Wash your plants with a gentle spray from a hose to remove substances left by smoke.
  • 24
  • Then give them a long, slow drink of water.
  • 25
  • Also, hold off on fertilizer until the air clears and plants fully recover.
  • 26
  • Edmunds said people should not use leaf blower machines to remove ashes from plants.
  • 27
  • You do not want to risk breathing in what is blowing around.
  • 28
  • "Always protect yourself as the gardener," she said.
  • 29
  • Ash can change soil chemistry.
  • 30
  • If you find more than a dusting of ashes in your garden after a wildfire, bring a little of it to an expert for testing.
  • 31
  • And if you live in an area where wildfires are common, plant smoke-resistant species that will better withstand future exposures.
  • 32
  • Native plants are usually stronger than those from other areas.
  • 33
  • Finally, if you find ash on vegetables and other food plants, Edmunds suggests washing them before eating them.
  • 34
  • Use a solution of one part vinegar and nine parts water.
  • 35
  • Or, she said, take the skin off the vegetable.
  • 36
  • The ash is on the surface only. Your food will be safe and tasty!
