'''Early summer'''<br />

The spring honey is usually used by the bee colony itself to grow up in preparation for the main nectar flow. Since the Nordic brown bees’ colony development starts slow, however, it does not support spring honey production. Despite this, it is sometimes possible to collect unifloral types of honey from the spring blooming season. The first main nectar flow usually comes from raspberry (''Rubus idaeus'').

'''Mid summer'''<br />

'''Late summer'''<br />

If there is a strong flow of raspberry nectar in [[Dalsland]], Sweden, honey harvesting will be done quite soon after Midsummer. But if the raspberry nectar is poor, harvesting will wait until the end of August or even the beginning of September. ''A. m. mellifera'' are very good at collecting nectar from heather ''Calluna'' sp.

The progress and timing of flowering can vary by several weeks from year to year. Spring flowers, for example, can bloom one month later in northern Scandinavia in comparison to southern Scandinavia. Moreover, the flowering season is shorter in the North than in the South. In any case, the main nectar flow takes place at approximately the same time just after the middle of the summer season.
