Hello there, Can anyone tell me how can I find out what citrus tree I have? I was pretty sure I have a lemon tree, but now I don't know anymore... I believe it is a grapefruit tree. Also the tree was seeded around 10 years now...but it never make a lemon or a grapefruit or any fruit of some kind. Please let me know if you have any ideas. Thanks.
The petioles of lemon and grapefruit are wingless and winged respectively. New growth from a lemon tree will have a tinge of purple. The juvenility period for lemon is relatively shorter.
