Why my black current bush flowers but doesn’t set fruit.
Leaves are perfect...no obvious blight. Great looking bush..about 5 yrs old....but no fruit sets.
Not all black currant cultivars are self-fertile. That means a second bush might be required for cross-pollination to set fruit. If you know your cultivar, you can research whether that is the problem. This document may be helpful: https://www.crfg.org/pubs/ff/currants.html
