In sweden my haskap honey berries are starting to flower. How long are flowers on berry bushes active for pollination?

Don't know for sure, but my guess from general principles would be 2 days. With most fruit the question is will the weather be warm and dry enough at the right time for the pollinating insects to get the job done - if you see any bees on your plants, that would be a good indication that things are OK.
