Lemon Tree
Question
I live in Yerushalayim and I have a lemon tree which was planted more than 4 years ago and gives fruit . I am a little confused about the whole subject of Maaser/ Tevel /Terumah - could you explain and how do i go about doing this especially when I plan to give to friends and neighbors some of the fruit. Also what other obligations are there in relation to the eating of this fruit from the tree
