I understand that it's only the female mulberry bushes that bear fruit.

Since my main interest in mulberries is the fruit - and my growing
space
is limited - I'd quite like to ditch my male seedlings.

That presents me with a problem - mulberries are slow to mature, and it
is
not obvious how to distinguish the male plants from the female ones
without
cultivating both for many years.

Any recommendations would be welcomed.
