NZL on C35 is available in norcal. I bought one last year at Walmart. ( i belive the tag said Hines Growers). C35 is a precocious semi dwarf tree > i think great for the home orchard.

I also have grafted NZL onto Volk. No fruit yet from either tree. I expect the Volk will make a larger tree. I am not that sure about fruit quality... My navels on volk are terrific and if there is any influence of the volk lemon, that may be a good thing for the NZL.

thank you, does four winds growers also use one of these rootstocks? I found a university article I will try to locate again which recommends a ponderosa rootstock I believe. But I may be wrong and will research that.

Here is the info I was referring too

Stick, that site does not refer to suggested rootsocks. It gives tree and fruit info ( and sorely needs updating and more info ).

Steve, that Florida document has limited relevance to California and home growers. .... and needs to be updated.

Thanks Molewacker, I guess I’m just looking for the best rootstock for best flavor and resistance to whatever Sonoma county soil tends to bring on. It will be a container tree for a couple years in a Air Pot until I decide to put it into the ground.

C35 has been the best performing rootstock for me in Napa. .... vs. CubanS, Volk, and Carrizo. CS does not have enough freeze tolerance, volk does well, but the tree size is too large for my spaces, and Carrizo is slower to get established. I hve trifoliates that do well too, but the grower cannot tell me exactly which variety of trifoliates they used. Good luck and let us know / post some pics of your efforts!

Thank you for your advice. I will start looking around for C35.
