Troedyrhiw has several types of trees, grasses, and weeds that produce pollen. Pollen counts rise during spring. Trees like oak, elm, and ash release pollen.

Grasses produce a lot of pollen in late spring and early summer. This makes it difficult for people outside. Pollen counts are usually high on warm, sunny days.

Weeds like ragweed and nettle also produce pollen. This happens in late summer and early autumn. Pollen counts can still be high in September and October.

Pollen seasons usually end in autumn. Weather gets colder and trees stop producing pollen. People can stay inside when pollen counts are high.
