Unusually dry conditions in August and September have set up what is potentially the most disappointing season for fall color in many years. Virginia Tech tree physiology expert John Seiler says he’s not encouraged about the outlook for a brilliant autumn season this year.
“When it gets this dry, everything just shuts down. At this point right now, it could be one of the least colorful seasons we’ve seen in many years.”
Even with recent rainfall connected to Tropical Storm Nate, it is already too late for certain types of trees and leaves.
“Lack of rain speeds up the process of trees dropping their leaves, as they quickly change from green to yellow to brown. It is especially true for some species such as hickories, maples, and poplars,” said Seiler.
The late summer, early fall dry conditions are not just particular to this part of Virginia. Seiler says colleagues as far north as New York state are writing about the lack of rain and its impact on autumn color.
Professor Seiler specializes in environmental stress effects on woody plant physiology, including water and pollutant stresses. Seiler is the Honorable and Mrs. Shelton H. Short Professor of Forestry at Virginia Tech and teaches in the College of Natural Resources and Environment.
