Lexington Pollen Report
Lexington sits at the center of Kentucky's Bluegrass region — horse country, where the famous pastures are largely forage grasses that pollinate each summer. Oak and maple bury the city's lush canopy in spring, the grass season is long and heavy, and ragweed fills fence rows and field edges in the fall. It's one of the South's tougher allergy cities.

What drives allergies in Lexington
Trees: oak, maple, and sycamore (March – May)
Lexington's mature canopy is dominated by oak (Quercus) and maple, with sycamore and black walnut contributing. April is the peak.
Grasses: bluegrass pastures (May – August)
Kentucky bluegrass (Poa pratensis) and tall fescue — the region's signature pasture grasses — pollinate heavily from late May into July.
Weeds: ragweed (August – November)
Ragweed (Ambrosia) thrives along fence lines and field margins throughout the Bluegrass, with counts elevated until frost.
Mold: humid, season-long
Central Kentucky's humid climate keeps Alternaria and Cladosporium active from spring through the leafy fall.
