Cherry bush not producing fruit.

[Sera]

A few years ago I bought a Nanking Cherry bush (Prunus tomentosa), and I was told it was self-pollinating, as well as read that on a few sites, however mine has never produced any cherries.
It has been transplanted a few times, and it flowers beautifully, but does it actually require a pollinator?

Thank you!

Try putting some mason bee boxes around your property. Also, plant other nectar producing flowers in your yard (if you haven't already done so.)

You will need another cherry to pollinate it. even another nanking will do, but almost any cherry that is in flower at the same time will do.

Good luck
