Actually I have 952 fruit and I don't let my villagers pick the fruit by themselves!! I don't have my 2nd level in faction yet so I always make sure my villagers aren't ticked off to be farmers until I can fish. It is my first tree and I have completed the orchard puzzle and both other trees have replenished themselves, one has replenished twice. I am nearly at tech points for level two and this tree has not replenished itself once!!
