|I have two maple trees (Aceraceae) in my backyard, great shade trees but a pain when it comes to the wing like seeds they drop all summer long. Last year I had one of them pruned back in the fall so it would not interfere with the house. Some of the branches were ten inches in diameter. The following summer, no seeds!! Of course this summer the seeds are back. My guess is that the tree produced some sort of enzyme to inhibited seed production so that all the energy could be channeled to the healing process. Do you know if there is such an enzyme, or whatever, that is available, or easily whipped up in the basement laboratory. I would like to stop the seeds once and for all!
