Allergies


We haven't even been back one week and it seems like we were never gone.

At least we missed some of the allergy season but it is still here.

Ragweeds bother a lot of people, they tear me up. That is why I always worked so hard to control weeds, I can't stand them, literally.

"Come late summer, some 10 to 20 percent of Americans begin to suffer from ragweed allergy, or hay fever. Sneezing, stuffy or runny nose, itchy eyes, nose and throat and trouble sleeping make life miserable for these people. Some of them also must deal with asthma attacks.

All this misery can begin when ragweeds release pollen into the air, and continue almost until frost kills the plant.

What Is Ragweed?

Ragweeds are weeds that grow throughout the United States. They are most common in the Eastern states and the Midwest. A plant lives only one season, but that plant produces up to 1 billion pollen grains. Pollen-producing and seed-producing flowers grow on the same plant but are separate organs. After midsummer, as nights grow longer, ragweed flowers mature and release pollen. Warmth, humidity and breezes after sunrise help the release. The pollen must then travel by air to another plant to fertilize the seed for growth the coming year.

Ragweed plants usually grow in rural areas. Near the plants, the pollen counts are highest shortly after dawn. The amount of pollen peaks in many urban areas between 10 a.m. and 3 p.m., depending on the weather. Rain and low morning temperatures (below 50 degrees Fahrenheit) slow pollen release. Ragweed pollen can travel far. It has been measured in the air 400 miles out to sea and 2 miles up in the atmosphere, but most falls out close to its source.

These annual plants are easily overgrown by turf grasses and other perennial plants that come up from established stems every year. But where the soil is disturbed by streams of water, cultivation or chemical effects such as winter salting of roads, ragweed will grow. It is often found along roadsides and river banks, in vacant lots and fields. Seeds in the soil even after many decades will grow when conditions are right."

I don't know about you but I know it is more than ten percent of the population affected and more than twenty in my mind. There were five of us yesterday in the barnyard and all were affected but one.

Then I had an asthma attack at bedtime. I had to prop myself up on the couch.

That never happened on vacation.
