A wind-pollinated fruit tree without nectar that offers a little spring pollen. Bees may suck juice from split ripe fruit in summer, but it has no honey value.
Black mulberry comes from Iran and the surrounding area and is a long-lived tree that has been grown for its fruit in Anatolia for thousands of years. Its flowers are short, greenish spikes and are wind-pollinated. It gives no nectar; the amount of pollen is also small for bees and is mostly collected only when other sources are scarce.
It flowers briefly in April-May, together with leaf-out.
It is not a honey source. When the fruits ripen in June-July and split or fall, bees and wasps may suck the juice. This sugar source is not a real flow; fruit juice carried into the hive can ferment quickly and spoil the quality of the honey.
In gardens with mulberry trees, wasp pressure increases during the fruit season; reducing the entrances of weak colonies cuts down robbing. The tree's value for beekeeping is limited to providing shade.
