Spring is a big pollen time. Trees like oak, birch, and hazel make a lot of pollen. It starts in March. April and May are also bad.
Grass pollen is a problem in late spring and early summer. June and July are peak months. Weeds like ragweed also make pollen. It floats in the air.
In autumn, weeds and trees make pollen again. September and October are pollen months. Then it gets quieter. Winter has very little pollen.
