In Genk, spring pollen season starts in March and April. Trees are the first to release pollen. Birch, alder, and hazel are common. Their pollen drifts in the air when days get warmer and buds begin to open.

Late spring and early summer bring grass pollen. This often happens from May to July. Many grasses around parks, fields, and roads release tiny pollen grains. Warm, dry, and windy days can carry them farther across Genk.

In summer, some weeds begin to flower. This is usually from July into September. Plants like nettle, mugwort, and dock can release pollen then. These plants often grow along paths, empty lots, and edges of gardens.

In autumn, pollen levels usually drop. Still, a few late plants may keep blooming into October. Ragweed is not common everywhere, but if it grows nearby, it can release pollen late in the season. Cold weather then slows most pollen release.
