Dianne Olsen of Putnam Cornell also wanted me to get the word out about extra seeds this year on silver maple trees:
According to Cornell University’s Branching Out newsletter, silver maple trees in many parts of the state are producing lots and lots of seeds.
“As these seed pods ripen, they turn turn and make the trees look unhealthy from afar. In addition to the “off color” look, leaves are stunted and shoot growth is much shorter than normal.
“All of this is because much of the trees’ food reserves are being diverted to allow for growth and development of the seeds. However, once the seeds are cast, normal growth should return.
“Massive fruiting like this is typical every 4-6 years but is nothing to worry about.”
