I'm another one that over seeds the tray and then can't separate them or bear to thin them
Orchard group told me to knock or cut off excess apples to allow the leader to grow bigger and sweeter, more what folk want to buy, and I've done what I can within reach but it really goes against the grain to waste fruit that might grow and be used..
I was also summer pruning the plums and took out some pieces that turned out to be growing fruit I hadn't noticed til I pulled them free

Felt like a complete waste
