Can you do anything to a cottonwood tree to prevent it from "snowing" its seed fluffs every year?
Question:
Answers:
Yes
nope, nature will takes it's course. unless you cut down the tree thats the only way to stop it.
no, other than cutting it down
Unfortunately no. You are talking about a large tree. There is no way to prune it so that the seed capsules can't send out their fluff. Sorry.
no this is the seed of the cotton wood. A plant's only goal in life is to reproduce.
The best you can hope for is stiff winds when the fluff starts to blow it away. I own lake property with heavy cottonwoods (The fluff works, they reseed vigorously!) and this year we had strong winds and the fluff is many miles away. Definitely a pleasure but rare that it happens. This is why Cottonwoods are undesirable for landscaping purposes. That and the fact that they are a "trashy" tree and drop a lot of limbs.
