In late spring, more trees and grasses spread pollen. Oak and pine may add to the mix. By May and June, grass pollen often becomes common in fields and meadows. Warm weather helps many plants grow and release tiny yellow grains.

In summer, grass pollen can still be strong in and around Irdning. Meadow grasses, rye grass, and other wild grasses are active through June and July. Some herbs also bloom. Their pollen can drift through the air on sunny, breezy days.

In late summer and early fall, weed pollen becomes more noticeable. Mugwort is a common example. It usually blooms from July into September. Toward fall, pollen levels often drop as nights cool and many plants finish flowering for the year.
