Spring Pollen Types

Eastern Oklahoma

Tree pollen is the major 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, the northern tier of states is just starting. In the Tulsa area, the spring pollen season has the highest atmosphere pollen concentrations of the year. The majority of the trees reproduce during this season. During April, we may see 20 or more different pollen types in the air on any one day. During the fall (ragweed may be worse symptomatically) but there are fewer types of plants producing airborne pollen.
