Spring Pollen in Eastern Oklahoma

Tree pollen is the major airborne pollen type in the spring. In Oklahoma and other southern states, the spring pollen season begins in February. The further north you go, the later the season starts. In the south, when we are nearing the end of the tree pollen season, it is just starting some of the northern states. 

In the Tulsa area, the spring pollen season has the highest atmosphere pollen concentrations of the year. The majority of trees reproduce during spring although there are some fall pollinating trees. During April, we may see 20 or more different pollen types in the air on any one day. 

Weeds that produce pollen in the spring include dock (Rumex), sedge family (Cyperaceae), and nettle family (Urticaceae). Also grass pollen (Poaceae) is produced in spring. In fact, grass pollen is typically at peak levels in late May.

Although the late summer and fall season (with ragweed pollen) may be worse symptomatically, fewer types of plants produce airborne pollen in fall.
