In Castell de Ferro, Spain, pollen seasons happen every year. They make trees and plants grow. This happens in spring, from March to May.

During this time, trees like olive, pine, and holm oak release pollen. They do this to make seeds. The pollen travels through the air, making the air yellow.

In summer, from June to August, grasses release pollen. They do this to grow more grass. This pollen also travels through the air, making it hard to breathe.

In fall, from September to November, some trees release pollen again. This makes the air yellow again. Then, in winter, from December to February, the trees rest and don't release pollen.
