Brian, my feelings exactly, the store bought ones (even way up north) were amazing. I’ve never had anything like them. It is grafted but I lost the tag a long time ago before I knew much.
I guess my question is whether anyone else has been in the same situation (semi mature tree, poor fruit so so), just chuck it out? I also have a sugar belle which is of moderate size and looks healthy but has not flowered ye, should I just focus my attention to that one instead? I wondered if they were much diffent.
