I am not a citrus expert but my Meyer's Lemon does not have any such prominent thorns on it, I will check tomorrow as I don't remember ANY. In fact, only my Seville/Bitter Oranges (which I planted from seed) have thorns like that. Even the leaves look off for a Meyer's Lemon.

Yeah other ones i have might have a few thorns but not huge ones.

I've never seen a Meyer with that many thorns but my seed grown eureka lemon has a lot of thorns like that.

Check to make sure it has a graft line down on the main trunk. If it does you are probably okay.

I certainly hope not. That way you may end up with a good tree.

My big Meyer has tons of HUGE thorns on it. So it could be. You'll know for sure when it fruits

Thanks, maybe there really is just a lot of variation in thorns.

My Meyer certainly has thorns. Some short, some longer. Definitely though if you have a very vigorous shoot, it will be in more of a juvenile, vegetative, and very thorny stage. I wouldn't remove it, as eventually it will settle down and bloom or branch.

Now, if your plant was grafted onto say, a rough lemon, the very thorny growth could be rootstock, but I can't tell if your plant was grafted or a rooted cutting. Many Meyers are propagated from cuttings as they are quite easy to root.

Yeah that was my concern too. They told me it is grafted on C-35 Citrange, but it almost looks like a cutting to me. All three of the main branches look the same, so im assuming it is all the same.

I would imagine, a crushed leaf would have a lemony smell if it's Meyer.

A citrange would have trifoliate leaves. I don't see that. Besides, I don't think Meyer is compatible with C-35.

Citrus macrophylla (rough lemon), yes, so that is a possibility.

They have strong scent so I think im in the clear! I just found an old picture that shows how I received it. It looks like a cutting. The second picture shows before I pruned the stock. Looks like lemon leaves, im pretty sure C-35 would be pretty distinct.

Yeah, probably a rooted cutting.
