500 to 1000 years for black mulberry.
Slow to rapid, depending on temperature.
10-50' high and 10-30' wide, depending on cultivar.
Separate male and female catkins, short and green, can be
present on the same tree or different trees, depending on cultivar.
In some cases, the trees can change sex. Male flowers produce
excessive amounts of allergy-causing pollen.
Yes, on many cultivars with female flowers or male
and female flowers, but seeds will be missing or non-viable if male
flowers are not present. Some female cultivars are non-self fruiting.
Years before fruiting:
2-3 if grafted, 10 years if grown from seed.
The "berry" is an aggregate fruit, with many small round
fruits clustered together. Dropped fruit will stain sidewalks and
carpets, although white cultivars are stainless.
Months for fruit to ripen:
2-3. Berries ripen a few at a time on
some cultivars. Black mulberries are difficult to pick
because they do not release from the stem, so scissors or clippers
are needed. In the kitchen, scissors are used to remove the rest of
the stems from the berries.
Storage after harvest:
Unwashed berries will keep two days in a
refrigerated, closed container. Freezing, eating same day, or
baking immediately is recommended. They can also be dried. Fresh
mulberry fruit is too delicate to ship and is not carried in stores.
Green, serrated edges, variable shape, turn yellow in fall.
Aggressive, extensive, lateral roots are no more than 2' deep,
extending beyond the tree's drip line. Smaller, vertical sinker roots
grow from the laterals. Keep these trees away from sidewalks, driveways
and foundations to avoid damage from roots.
