Nectarless; bees gather its wind-borne pollen in early spring, and its bud resin is an important propolis source in Europe.
Silver birch is a wind-pollinated tree and produces no nectar. Its male catkins release large amounts of pollen in March-April; honey bees collect this pollen, especially when other sources are scarce. However, the protein value of birch pollen is lower than that of willow or fruit trees.
Young shoots and buds secrete a sticky resin. In northern and central Europe it is counted, together with poplar, among the most important propolis sources; propolis from these regions contains compounds typical of birch buds.
Aphids feeding on the leaves leave some honeydew in certain years; bees may collect it, but not in quantities that would yield a separate honeydew honey.
In Turkey its natural range is limited to north-eastern Anatolia, but it is often planted in parks. Birch gives the apiary early pollen and propolis but cannot carry spring build-up on its own; sources such as willow or plum need to be nearby.
