The Weed Behind Oklahoma’s Worst Fall Allergies

There’s no big mystery to fall allergies. Most of the misery comes from one unremarkable, stubborn plant: ragweed.

It’s so common across the country you’d think more people could pick it out of a lineup, but most couldn’t. That’s probably because ragweed comes in a few dozen flavors, all equally good at ruining your day. Around here, the variety we wrestle with is Western Ragweed.

What Exactly Is Ragweed?

If you’ve ever heard an older relative call something a “careless weed,” they were probably pointing at ragweed. Which is weird since "careless weed" is something completely different.

Similar to actual careless weed, ragweed pops up anywhere it pleases. Doesn’t matter if it’s a sidewalk crack, the middle of a gravel lot, or your freshly mowed yard. It’ll sprout up tall and scraggly like it owns the place.

Drive past the I-44 and Gore Boulevard intersection and you’ll see what I mean. That corner’s basically one big ragweed farm right now.

Does Ragweed Have a Purpose?

You probably wondered... Why does something so useless to humans even exist? Biologists will tell you it’s good for wildlife. Quail, doves, woodpeckers, and the occasional rodent think ragweed is a buffet. Native Americans even used it medicinally as an antiseptic and a fever reducer.

That’s all fine, but let’s be honest: for the rest of us, it’s just a plant-shaped box of tissues waiting to happen.

When Ragweed Season Peaks

The season kicks in when we hit that perfect storm of cool nights and warm days. Every temperature swing is a signal for ragweed to pump pollen into the air like it’s on a mission.

Some folks start sniffling in mid-August, others get the sniffles by now, but things generally settle down by the middle of October. So if you’re counting the days, just hang on.

How to Make It Through Ragweed Season

• Stay indoors if you can. If you’ve got to mow or work outside, wear a respirator. I use an RZ Mask. You'll look stupid, but it works wonders. And skip mornings, pollen’s heaviest in the morning. Evening’s better.
• Watch your diet. It sounds weird, but foods like melon, bananas, sunflower seeds, and even honey all share a protein with ragweed that can make your symptoms worse.
• Stick to what works. Pills, sinus rinses, allergy pills or shots...everyone’s got their go-to.
• When you come home, toss your clothes straight in the wash and grab a shower. Otherwise, you’ll be spreading microscopic pollen through your house and into your bed.

We’re heading into the thick of it now, with a few weeks left. The Wichita Mountains are loaded with ragweed this time of year, so expect things to peak before they get better.

Good luck, see you on the other side of October.
