Sanford for comparison, about 80 cm high

Hello Ilya, sorry for your Taitian Pomelo, but the behave of the crosses sounds good and 1m is already a nice size. Interesting to follow the progression  . Best regards Frank

nullroar, I rhink some of your mentioned varieties are pretty good for 7 b, especially Prague Citsuma, which survived last winter -16 Celsius with not much passive protection and a smal plant. Also planted in my garden survived Sanford Curafora and Morton Citrange which should have edible fruits. But why don' t you try parallel citrus in pots ? I have good results with Chandler Ponelo and other delicous citrus varieties and in winter they are in a small temperature regulated greenhouse 😀.
Regards Frank

very interesting article Millet  , this could also be a good method for colder climates. The only problem is to have enough space/ good place for a large greenhouse. The only thing is, after my short experience, the nutrition of potted citrus is more complicated than citrus planted free in the soil.
Regards Frank

Thank you Millet for the further informations, yes the mealy bug is also a very ugly beast, I had him once in cacti 
best regards Frank

I found two citrus plants in my collection with a lot of scales. I sprayed them with oil and hope to get rid of, in former times, with only one lemon I had good results. But now I found still at two other plants in my collection a single scale, which I removed by hand.
Now I ask me if I should spry before overwintering all my citrus (ca. 70 pots)? I will overwinter them by 1 ° C in a greenhouse).
Who have good experiences how to protect, prevent scales.
Thank you Frank

Hello Platinyum,
I had the same question with my Chandler Pomelo last year, and in all articles I read that Pomelos need 10 ° C in winter to get good fruits.
But I feared in the house not to have enough light or to get insects on the plant, so I tried to cultivate my Pomelo in my greenhouse with a lowest temperature of 1 ° C  and when I harvested the last of 4 pomelos in April, I was content with the quality of the first fruits grown in my climate in zone 7, summer on terrace and from Nov. to april in greenhouse.
Regards Frank

Thank you Till, so I think for my two fruits I still have to be patient with harvesting, but I' m happy to hear the fruits are good. Also curious how my Sanford in ground will master her second winter 🤔, while the recovering was extremely good.
Best regards Frank

Thank you Mikkel, If I understand right you already had fruits on your smal tree, did they taste good ?

Thanks Florian for your information, so I' m glad to hear the fruit seems to be good tasting. For your plant I wish you good luck that the fruits still get ripe. The fruits of mine are still very small, lets see how they grow ? Climate conditions this summer are not very favorable in Germany.
Regards Frank

Poncirusguy, sorry for the delay, here the pictures

Ichangquat, after snailattack to fresh sprouts I hadto repot, but now only rootstock sprouts  , don' t know if the ichangquat will survive.
regards Frank

Yes, I regret not to have taken the plant into pot directly after winter for recovery. But the last years we nearly had no snails so I didn' t took that into account.
But you are right, that bigger plants have no problem to loose a few leaves or sprouts by snails.

Summer update of my survivors which suffered most.
Sanford with strongest recovery
