Still no relevant pollen count!

The cold snap last week did not allow any pollen count. It will remain cold in most regions of the country in the coming days. Therefore, localised pollen counts are only to be expected in very thermally favoured locations.

In these places, the purple alder can cause pollution. However, even this plant, which is actually known for starting to flower around Christmas, will only be able to release a small amount of pollen due to the expected conditions, although a number of catkins still have flowering potential.

In the alder species that are more widespread in this country(black alder and grey alder), the catkins are still firmly closed and therefore cannot yet release any pollen. This also applies to the tree and shrub hazels.

The cold spell also has an impact on the flowering readiness model. From a current perspective, the data tends to indicate that flowering readiness will be reached between the beginning and middle of February.
