I have three Evergreen Ash trees in my backyard that are approximately 33 years old. We were the ones that planted them originally, however I don't really remember if we had the problem I am about to explain when they were younger. This year, more than any other in the past, the trees have shed narrow elongated seeds/flowers of some kind. My daughter is home with a broken ankle and the other day when the winds blew so hard, she said it looked like it was snowing. Is there any way to spray the trees to keep them from setting these particular droppings? They have become quite a nuisance with regard to the pool and surrounding yard. They are difficult to pick-up as they are brown and brittle. They are on the tree all year long, remain green, and do not cause any problem. However, once fall comes, they turn brown and continue to fall throughout the months of August, September and October. I know olive trees can be sprayed so as not to set their blooms, so I was wondering is there is something similar for the Evergreen Ash? Any help you can provide would be sincerely appreciated.

Ash trees are known for heavy seed production as they mature. However, weather conditions, health and the age of the tree are also contributing factors in how many seeds a tree produces each year. Consequently, some years might not see an overabundance of seed. There isn't much that can be done to stop seed production. If it is a major problem the only solution might be to replace the trees.
