Both Prok and JT-02 are somewhat known to be droppers when they’re younger, though not as bad as Nakita. Some people seem to get lucky and have the right combination to avoid it, but I found both took a while to really hold much fruit.
This was year 4 or 5 with my Prok and there was more fruit than I could eat, but last year she dropped a couple hundred and only held a dozen or so. Hopefully we are past the dropping years now. We’ll see this year.
