I'll explain the "8 tree trick"

1) There is no such thing as the 8 tree trick. There is no bug. Someones when your farming and you place trees side by side the waytering can is able to water two trees at once. I am able to do that a lot of the time, which means I can water 4 trees

2) The "8 tree farming trick" does not work all the time. Somtimes you can't get into the "zone" (like Corpse has said) and it doesn't work, but everytiome you go water your trees you have another chance to get back into the "zone" to water two trees
