I’ve never had success with avocados but I’ve seen many do it and it’s really neat. Mine always crack open like they’re about to take off but the shoot never emerges. I’ve even applied hormones to trick it but nope, nothing.

@MuddyBoots apples are an interesting experiment. Apples are cross pollinated so you never know what you’re going to get and unfortunately it’s likely to be inferior just because the way genes shuffle.

Tree breeders live an interesting professional life. Due to the long life cycle they finish their predecessor’s work while your successor will finish yours and so on. And that’s whether it’s for fruit or wood or whatever product you’re breeding for. Some of that is changing now that molecular genetics tools are taking over but you still have to wait to see what the real result is.
