Weed Pollen Allergies

Weeds make you sneeze? You’re not alone. 20% of Americans are plagued by weed allergies. Weeds multiply and produce large amounts of pollen fast. Learn more about managing these powerful allergy triggers.

  1. What it is

    Weed pollen is abundant from late summer to early fall. Mid-September, when pollen levels peak, is particularly bad. You’ll be most affected by these allergens on dry, hot, windy days when weed pollen is at its worst.

  2. 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.

  3. What to do

    • Learn to recognize the weeds that trigger your symptoms.
    • 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.
