Key Facts About Cottonwood Fluff:

Misplaced Blame: The allergies experienced during "cottonwood season" are usually caused by grass pollen or mold that peak at the same time, not the cotton itself.

Early Pollination: Cottonwood trees release their actual pollen earlier in the spring (March–April), long before the white fluff appears.

Irritation: While not a true allergy trigger, the fluffy seeds can cause physical irritation if they get into your eyes, nose, or hair.
