One of my trees in the orchard won't replenish itself, the other two do with no problem. Can someone help?!!

What does it say when you click on it?

Maybe that one tree has the villager's favorite fruit!
Seriously though, it's most likely that your farmers are picking fruit off that tree before it registers. As well as clicking on the tree often like Laurence suggested to see what it says, also keep an eye on your food bin. You may see the difference there.

Unusual that they pick one tree clean and not the other, but it is highly normal for farmers to strip a tree so quickly that you never ever see it with anything but 8 or 9 fruit, which is about where villagers stop harvesting it. (Less than that, and you get the message that there isn't enough fruit to harvest.)

Trees should replenish 111 food each, every three hours.

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!!

I have noticed that villagers, once they have learned to farm, will pick fruit on thier own. If you are playing, you can stop them...but if the game is closed they will go ahead and pick away on there own.

If you are close to finding another food source, with 952 fruit, your village should be fine and able to sustain...if the population isn't too high. And, I don't think the villagers get terribly 'ticked-off' Well, they may complain a bit but it will be to some random villager, tree, statue...then, back to work!

Yes, please, tell me how you have any food at all if you never trained any farmers? Because the only way to keep them from harvesting is to either never train a farmer, or to wait for all your farmers to die. Even without being checked for farming, if they have the skill they will still strip trees - perhaps not as zealously, though.

By 'replenish,' do you mean boosting all the way back up to 1000 fruit? It sounds like you might be. That is an event-based boost. The trees get boosts of 111 fruit every 3 hours - there's no other regular replenishment, only event-based refills.

Yes I do mean boosting up to 1000. I don't train any of my villagers to be JUST farmers. They all get trained to Trainee level in building, farming and research at the start of the game. I currently have 12 villagers (I got an event where I had a barrel of babies which were actually two ten year olds who are now 15). I have three Master builders and three Master Researchers and one Adept Researcher. The rest are kids, I have a child chief too. Three of my villagers are adept farmers because I wanted to solve the weather dance puzzle. I made them adept by dropping them on the hive but not allowing them to reach the food bin with the honey. One is also a Master researcher and the other two Master builders ( both are runners too!!) At the moment I have 2568 food, three trees at 960 and 360 in the hive. All done by allowing the kids to collect mushrooms by pausing the game and dropping at least three kids on the mushrooms. I have been lucky enough to get a lot of red mushrooms in this game which helps a LOT! I have now got fishing and I occasionally send someone off to fish to keep the food stocked past 2500. With such a small tribe I find it easy to keep track of them so if I notice anyone going off to harvest honey or pick fruit I stop them! Anyway, my tree did come back to life a few hours ago so all is good !! I've played a few games where I try to keep just the kids responsible for food and so far I haven't lost anyone to starvation!

I do much the same thing in the early part of the game -- as long as the villager has at least trainee level in farmer, they'll harvest honey or pick fruit occasionally (and more often if the food stores are low) - even though they are assigned to other jobs. It works for me until the population gets above 15 or so; after that, I have to start assigning villagers to farm.

They won't do this if they don't have any farming skill, so you have to train them a bit (I go all the way to trainee to be safe, but that may not be necessary). It's a great way to maximize your number of researchers early in the game.

I think this was a tweak from the behavior of peeps in VV2, who would endlessly worry about an empty food bin while the crops sat unpicked in the field.

Wow, you've been working really hard! Did you know the fishing is limitless? By that I mean, once you have fishing, the village food supply will not run dry under normal play. You will still have the fruit and honey but it is not necessary to sustain the villagers. So, as far as starvation goes, allowing the villagers to deplete the trees and hive will cause no harm...now that you have fishing and trained farmers.
