Mar 31, Pines, the most dominant group of trees in the park, begin to produce pollen in their annual reproductive cycle. Pines are especially interesting because they produce separate male and female cones.

These are general forecast tools and should not be viewed as the definitive answer to when particular pollen types will be present in the air.

The pollen produced by male cones is carried to female cones by the wind. This is a very old strategy as pines are first found in the fossil record. While tree pollen levels will be going down, Mother Nature still has more in store for us."Grass [pollen] when does pollen stop falling from pine trees starting and grass will get bad toward May and then into June and July. And of course Author: WWBT. The US Forestry Service says: “The date of peak pollen shed depends on the accumulation of degree-day units above 55° F after February 1.” You can use the Degree-Day calculator at Georgia Weather Net to display how many day-heat units (degree-days) have occurred since Feb 1.

See An Easy Way to Predict Flowering of Southern Pines. May 29,"We are at the end of the yellow stuff but pollen is in the air from March until the fall frost. First it is trees, followed by grasses and then the weeds," Hawk said.

Ultimately, that’s what pollen is: the means by which a tree transmits its DNA from the stamen (the “male” part of the plant) to the pistil (the “female” part).Estimated Reading Time: 4 mins.
