when is prime time allergy season
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.
