My lemon tree has a long shoot with leaves that are yellow curl up. I do not like the long stem. Do you think it would be okay to cut it off or would that harm it. I would like to keep it small.
The most important thing is this is not a lemon! No true lemon has a winged petiole. You may be just growing a rootstock.
It was from a seed out of my lemon, could have been an orange or grapefruit.
crush a leaf and smell it; that should tell you if it is an orange or a grapefruit.
