Citrus General Discussion / Re: Eureka Lemon only growing below graft
« on: Today at 05:34:03 PM »Does my rootstock look like C35?
I'm not sure what C-35 leaves look like, maybe someone else can answer that. But it's definitely either trifoliate or some trifoliate hybrid like citrange (C-35, Carrizo, etc), and Eureka is incompatible with most of those. Did you happen to save the original nursery tags or photograph them? The rootstock is sometimes coded on them (e.g., if it has CZO in the code then that's Carrizo).
Unfortunately, I’ve lost most of those on my 35 gal trees cause I just wrote the name on the pot and didn't think to note the rootstock; I’m just learning the effects of rootstock on citrus now and seeing how important it is. I attached pics of the ones I do have, which all seem to be doing well with no signs of incompatibility.
Thanks again for your help in figuring out this problem!
