In Leuven, Belgium, trees start producing pollen in late March. This is the start of pollen season. Birch and oak trees release pollen into the air.

In April, grasses and weeds join in, releasing even more pollen. This makes pollen counts very high. People who react to pollen might start to feel symptoms.

In May, grasses and weeds release less pollen. Tree pollen is still present, but not as much as in April. Pollen counts start to go down.

By June, most trees and plants have stopped releasing pollen. Pollen counts are very low. The air is cleaner, and symptoms usually go away. Summer is pollen-free!
