    Does any one know why my weeping birch is attracting black flies? It's dripping a liquid from it's branches, could that be why?

    Thnx

    if it has been pruned lately it may be emitting sap. This may be attracting flies.

    Also a magnet for aphids ("blackfly" in UK), which make it drip honeydew during summer.
