In spring, more trees add pollen. Oak, pine, and plane trees are common. Their pollen often appears from April to June. This is a busy time for the air. Fresh leaves grow, and many trees are sending out pollen at once.

In late spring and summer, grass pollen becomes important. Grasses in fields, lawns, and roadsides release lots of pollen. This season often runs from May to July. Warm, dry weather can make the pollen stay in the air longer.

In late summer and early fall, weed pollen can rise. Plants like mugwort and plantain release pollen then. This period is often from August to September, sometimes longer. As summer ends, the air can still carry pollen from these plants.
