I know what you want to do.............an EXPORT QUALITY fruit............
I´m searching to do the same with my Cavendish..............
First I just leave the Plant grow freely...........including keep the inflorescence...........
Many many fingers split...............
Maybe too thick...........or something.................
Then I made a try in the subsequent bunch..............
I remove the bell...............and I pruned all outside fingers.............
Check my thread with pictures.................
Bunch Question...........
