KS pollen report
Topeka Pollen Report
Topeka sits in the Kansas River valley where the eastern hardwoods meet the tallgrass prairie — and it gets pollen from both. Oak and walnut bury the city each spring, prairie and lawn grasses carry the summer, and Kansas is ragweed country: fall counts are reliably heavy until the first frost.

What drives allergies in Topeka
Trees: oak, walnut, and cedar (March – May)
Oak (Quercus) and black walnut drive the spring, with eastern red cedar starting as early as February in some years. April is the peak.
Grasses: prairie and bluegrass (May – August)
The Flint Hills' tallgrass prairie and town lawns pollinate heavily in June.
Weeds: ragweed (August – frost)
Kansas grows ragweed (Ambrosia) abundantly; September counts are among the heaviest in the Midwest.
Mold: river valley and harvest
Kansas River humidity and the fall harvest keep Alternaria and Cladosporium active through the warm months.
