Do you check at 1/3 of the time, then half?

When it's fully grown.

Yes, you only gain exp once per tree, and that's when it has fully grown.

 

 

 

 

 

 

 

Or do you mean when do you check if it's fully grown. I usually check every 4 or 5 hours for trees, and overnight for fruit trees.

you know, i really do try to farm....but i just can't =\

 

 

 

 

 

 

 

I have checked like 2 trees in my whole rs experience, and i know that you can only check the health once.....
