Question: I started a grapefruit tree from a seed a year and one half ago,the tree is now about two feet tall and has thorns on it. The tree seems to be doing great but I don't know what to make of the thorns. Are they common?
Answer: Thorns are a perfectly natural development on grapefruit trees so there's nothing to be concerned about - except, perhaps, accidentally sticking yourself if you're not careful!
