1. According to a FAQ, in order for an etrog tree to be considered kosher it must be grown from seed or from a cutting (and not grafted). In addition "...there are some important Halachot (Laws) which must be considered when the tree is transplanted or repotted." and "Note the Laws of Orlah regarding replanting.". However there is no explanation as to what these laws are. Can anyone provide insight into them? 2. What happens to the etrog fruit once the Feast of Tabernacles is over?
