Trees
Tree pollen season arrives in the early spring, and can come from over a dozen common tree species. As a general rule, trees with fine, powdery pollen are the worst offenders. Trees in the western United States tend to produce fewer allergens.
GrassesGrass pollen is most prevalent from May until July. Bermudagrass, Kentucky Bluegrass and Ryegrass are common lawn grasses that cause allergies. Grasses only produce pollen if they can grow flowers at the top, so if you can keep your lawn mowed, that will decrease the production of pollen.
RagweedRagweed pollen typically files from August through October, and is the most common trigger for hay fever, also known as allergic rhinitis. Ragweeds grow in every U.S. state except Alaska, but are most common in the East and Midwest.
MoldAirborne mold spores can cause allergic reactions when inhaled. Spores are microscopic particles that form as mold reproduces, and can easily trel through the air. Mold can be present year-round, but symptoms are most common from July into the early fall.
