In Siena, Italy, trees start releasing pollen in late March. This is when olive and cypress trees shed their yellow powder into the air.

April is the worst month for pollen. Oak and birch trees join in, releasing even more pollen. The air is thick with it, making it hard to breathe.

May is slightly better. Fewer trees are releasing pollen, but it's still present in the air. The good news is that more flowers bloom, adding color to the city.
