I took 35 foot off mine and left me with three stumps. It still sprouts
prolifically every year and grows shoots of up to 8 foot in one season.
I cut it back in the winter but it certainly recovers well

Your black mulberry is a law unto itself. Grows twice as fast as the
average black mulberry and has insipid fruit instead of the luscious
full flavoured fruit one expects.


Ah but I grew it from a seed so I guess that explains the variation in
type?
Makes superb whippy stuff for a friend who does a great deal of living
willow sculptures and basket work etc.
