Back to ragweed: With a capability to grow in all sorts of conditions, ragweed inflicts its allergy agenda in all 50 states. Just one plant is capable of producing about one billion grains of pollen in single season. Research shows just 5 to 20 pollen grains per cubic meter can trigger ragweed allergy symptoms. To put that into perspective, ragweed pollen grain concentrations readily hit 200 during prime allergy season in the midwestern U.S. (2) Again, most people think of springtime as prime time for allergy season.
Pollens spread by the wind. Pollen from trees, grasses, and weeds are the main cause of allergies. Spring is not the only allergy season, many plants pollinate year round. Your location will determine the time and duration of your pollen season. Pollen counts will vary from day to day as well as hour to hour. Different Pollens for Each Pollen Season . In springtime, pollen from the trees begins its release between January and April, depending on the climate and location. These trees include elm, pine, birch, ash, hickory, poplar, and cypress to name a few. Summertime is when grass pollen reigns supreme: pollen from northern grass in colder climates, such as timothy, rye, and blue; and southern grass pollens in the warmer climates, such as Bermuda Grass.
