Q.Thorny Lemon Tree

Zone pasadena, calif 91104 | Anonymous added on September 3, 2021 | Answered

The 2 yr old lemon tree I planted was commercially purchased and was supposed to be a variegated pink lemon. It is now 5 yrs old and has no fruit, no variegated leaves, and has very large killer thorns! Should I cut down this tree?

It is likely that at some point the desirable top portion of the tree died and the rootstalk took over. Most citrus is grafted onto a more durable rootstalk, which can take over if the suckers are not removed. Rootstalk varieties rarely produce fruit.
