Spring is a big time for tree pollen. Oaks, beeches, and chestnuts make a lot of pollen. It starts in March and ends in May.
Grasses make pollen in late spring and early summer. This is usually in June and July. Weeds also make pollen, but less than trees and grasses.
Pollen counts are usually lower in winter. But some plants make pollen all year. People who are sensitive feel it more when pollen counts are high.
