It depends if you count the ones I killed, or Mother nature did! Although the more plants you kill, the better gardener or orchardist you become! As you discovered already!
I never kept track of percentages, I have killed just about everything you could imagine in the last 40 years. I didn’t start with edibles though. So the first deaths were houseplants. Although i do have plants from the very first year, yes they are 40 years old.
This year I lost a couple currants, a plum tree, 2 blueberry plants (i was hoping one would make it). Also an exotic Sherbet plant (I have another that is bigger, the first was so small).
