Eric Berg with the service says the resilience of trees to
flooding varies by species, age and health of the tree before
flooding, among other things.
Standing water, he says, is damaging, as tree roots need to obtain oxygen.
Berg says symptoms of flood damage include leaf yellowing, early
leaf drop and dieback at the crown.
He says landowners can help alleviate damage by redirecting
standing water, if possible, and covering exposed tree roots to the
original soil depth.
If more than three inches of soil has been deposited, it should be removed from the root area. Encrusted soil over roots should be scraped to improve oxygenation.
