Key Lime Thorns
I am growing a key Lime for the first time this year. It came from Stark Brothers as a very small plant this Spring and has grown quite well. It now has very long pointy thorns on it and I am getting concerned that they will continue to grow in proportion to the size of the tree. Do all citrus have thorns like this? I had no idea it would get such sharp thorns!! It is about 12-18 inches high and has spread to about 12 inches wide and I will be taking it inside soon since I live in zone 6 and it cannot stay outside.
