What should i do with this pomello

[Plantinyum]

This plant has set two fruits , i am wondering what to do with it over the winter, i am assuming that they should ripen next year arround summer so can i keep it in a basement without strong light and temps arround 2-5 C. Theese temps are the maximum lowest ones that i get in there in the dead of winter, it can get a little colder thought at arround 0-1 C at rare times.
Will the fruits drop?? They will definitely stop growing ,but the question is if they do not drop ,will they continue their growth next spring??

The alternative is to bring it in my greenhouse ,which i will heat .
What is the minimum temp a fruiting pomello can withstand without damaje to its fruit? The plant is grafted on flying dragon btw.
Thanks !

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

thats nice to hear that u had good fruits with such a low temp. I will then place my plant in the greenhouse , i will try to maintain a minimum temp in there thats above 0C . Hope those fruits ripen for me and have some seeds in there so i can grow out seedlings to graft the variety onto, pomello does not perform really well for me on flying dragon rootstock .  Thank u for the feedback !!
