Florian,  But wouldn't you then pick varieties that reach high sugar levels earlier?  So the Miho, Miyagawa and China S-9 would be best for you according to this, assuming you have those available in your part of Europe (Tintori maybe?).

Yes, you are right. But when I bought the Iwasaki, I did not know about this and now I have it and I love it. I do have a Miyagawa as well and will probably plant it out too.

You could try Squadrito they have it and usualli sells bigger plants than others

Awesome, thanks! They really seem to have the NZ Lemonade. For now I will wait and see if Florians grafts will take, but if they fail I'll try to order from them.

I grafted them on August 29. One is still green which means it has probably taken. The other one is so tiny that I can't see the colour through the parafilm. If only one succeeds, it will be another year or so before I can share cuttings.

Prague is a tough one to figure out. Mine bloomed twice this year, but set no fruit at all. It looked like most, if not all, of the flowers were staminate. I don't know if there is a way to induce the plant to produce more pistillate flowers, or if that's even possible, or if some clones naturally produce more than others.

Mine always flowers profusely with a lot of pistillate flowers and still manages to drop all of them most of the time. The few fruits that stay on the tree stay small and drop at a later time. In fact, had I not had some beautiful fruits on it when it was still potted, I'd say it is incapable of producing decent fruits at all..

In my climate, I remove any tender shoots after late August. They will be dead anyway. But I can't say if other flushes harden up quicker this way. I would not think so.

I have not attempted such a cross but it would certainly be an interesting endeavour.

Yeah.. they're all dead. They were weak from the start and their condition slowly deteriorated. I tried to micrograft some but most didn't take and the survivors were eaten by snails/slugs in one of the wettest Mays we have ever had. Even slug pellets could not help.

That's a bitter disappointment. I wonder what incompatibility lead to the poor vigor.

I have an inferior strain of ichangensis, but regardless if it blooms next spring, I will probably pollinate my own clementine with it, or vise-versa. Clementine was the mother in your cross?

Yes, clementine was the mother, hence I wrote Oronules × ichangensis and not the other way round .

 I am going to try again but my Oronules did not flower this year.. And I managed to acquire an even better ichangensis than my IVIA which I want to use in the cross. It is seedless when there is no cross pollination.

Thanks Usurius. I once tried to find information about Dr. Frey but was unsuccessful. I didn't know you knew him.
He must have had an awful Yuzu since he found both Curafora and Livurce to be superior to his Yuzu..

I find it a bit sad that nowadays, it is hard to find any information about the origins of many hardy citrus varieties. I have been to Eisenhut nursery many times but when I ask Reto about a certain plant, he mostly just shrugs his shoulders and cannot provide any details.

Similar story with Bernhard Voss. I used to write him e-mails but hardly ever got an answer and when I met him at the Wiener Zitrustage he sold me a mislabeled Citrumelo 5star. It hasn't flowered yet but could be his hybrid Nr. 3.

Now, who volunteers to organize this? 😀

Here, we usually say: The one who asks!
I am too busy at the moment but I would certainly attend such a gathering.

Not even Eisenhut nursery has it, and they have over 500 different Citrus :S Plus I can always try to graft them myself if I have something to start with.

Yes, they have it: https://www.eisenhut.ch/de/shop/citrus-lemonade-z148_z148

Depending on how much space you have, you could also plant a strong rootstock, then graft multiple varieties of Yuzu and other hardy citrus onto it and let mother nature do its thing until you are left with what can grow there. Many people will send you scionwood for free or if you cover postage. At least I would .

The issue with the bark is only on the Citrangeremo. By the way, both plants came from Adavo.
I am not too disappointed because I only have a small garden and no space to waste (the Citrangeremo is in fact in my grandma's garden).
Soon, other hardy candidates will take the eremo hybrid's places.

My glauca x shekwasha looks quite dead after its first winter while all my other citrus look ok. We only saw -6/-7 C. I don't protect any of them.
