Learn about weed pollen and how you can manage this powerful allergy trigger.
1. What it is
You’ll be most affected by weed pollen on dry, hot, windy days when these airborne particles are at their worst.
2. When it is in season
Weed pollen is abundant from late summer to early fall. Mid-September, when pollen levels peak, is particularly bad.
3. What to watch out for
Ragweed is the biggest troublemaker of all weeds. A single plant can produce a million grains of pollen every day. Other highly allergenic species include Sagebrush, Redroot Pigweed, Lamb’s Quarters, Russian Thistle and English Plantain.
4. What to know
Learn to recognize the weeds that trigger your symptoms.
5. What to do
- Remove brush and weeds from your property.
- Mulch with rocks or plastic gravel to stop weeds from growing.
- Learn when pollen counts are highest in your area. Rural areas host more Ragweed plants, raising pollen levels before dawn. Wind can carry Ragweed toward urban areas, reaching them by late morning.
