Orlah Indoors In Unperforated Pots

Trees growing indoors in unperforated pots are subject to orlah miderabanan (they are considered disconnected from the ground; here the barrier is twofold: the tree is in a pot, and there are tiles on the floor).

After orlah years are up, it is possible to partake of the fruit. However, if the unperforated pot is brought outside to the garden or transplanted into the ground, orlah years need to be recounted, since the tree is now subject to orlah mideoraita!
