Sucker of Mulberry producing red berries, original tree nothing?

Question

I planted a box Mulberry tree 3 years ago. One trunk, last year I noticed suckers on the bottom next to trunk, I left it alone. This year that sucker next to tree is growing beautiful red berries, the original tree has grown and healthy, why does the original tree not have fruit. I wished for a fruiting mulberry now I have one and don’t know how this has happened. Can I take cuttings from the fruiting sucker to get another tree? thank you in advance for your help, as I am perplexed with this tree.

Answer 1

It may be that you have planted a fruitless mulberry, or ornamental mulberry that was grafted onto a fruiting root stock for vigor. If you want the fruiting mulberry, the best thing to do will be to root a cutting from the fruiting rootstock.
