Trees bloom in Hannover from March to May. This is when birch, oak, and hazel trees release pollen into the air. People with allergies get symptoms during this time.

From mid-May to June, grasses release pollen. This is the worst time for people with grass pollen allergies. They try to stay indoors when it's windy or sunny.

In July and August, weeds like nettle and sorrel release pollen. This is a smaller pollen season, but some people still get symptoms. They should be prepared for bad days.

In autumn, from September to November, mugwort and wormwood release pollen. This is the last pollen season of the year. Then, winter comes and pollen counts go down.
