It’s the middle of September, and that means we’re in the peak of ragweed season! And for many North Texans, that equals six to eight weeks of itchy, watery eyes, sneezing and chronic coughing.
In North Texas, the season ranges from mid-August through November, when we get our first hard freeze. The average end date is November 22.
Ragweed flourishes during hot, dry spells. The dry heat promotes growth and increased pollen formation. One plant can produce as many as 1 billion grains of pollen each season. It’s estimated that nearly 100 million tons of ragweed pollen is produced every year in the U.S.
The only thing that makes it difficult for the plant to release its pollen is relative humidity that exceeds 70 percent, a rarity in North Texas.
And just to bring even more tears to your eyes, ragweed is not the only allergy aggravator! Many tree pollens — such as elm and grass pollens — are working overtime right now. Each of those two pollens have been registering on the high side this past week. Our body’s reaction to an air allergen is known as seasonal allergic rhinitis, or hay fever. Roughly 36 million Americans suffer from it.
Not the best of news, I know.
But, let me leave you with a silver lining. Fall begins next Wednesday with the arrival of the Autumnal Equinox at 10:09 p.m. And, as we all know, the sun slipping south of the equator means cool, crisp mornings and mild afternoons are soon to follow.
