Tucson, AZ Mulberry Pollen
Mulberry pollen in Tucson usually peaks around March, reaching High at its worst. Tucson sits in the Sonoran Desert, where native and planted trees stretch the allergy season across most of the year: juniper and cypress in winter, olive and mulberry in spring, and mesquite into early summer. Pima County restricts the trees that cause the worst of it.
Male mulberry trees release heavy, highly allergenic pollen in early spring. Pima County restricts planting mulberry for this reason.

Managing mulberry season in Tucson
If mulberry is your trigger, start a daily antihistamine like cetirizine (Zyrtec) or loratadine (Claritin) a week or two before the March peak, rather than waiting for symptoms. Keep windows closed on high-count mornings, shower and change clothes after time outside, and run the AC on recirculate in the car.
When symptoms don't ease with over-the-counter medicine, an allergist in Arizona can test whether mulberry is really what you react to and talk through longer-term options like allergy shots.
