Thank you Ilya.

Btw, what was your lowest temperature? And do you also get prolonged frost?

My ichangquat is planted out at the good protected south eastern wall of my house. It took similar temperatures as yours moro. It is untouched and looks in perfect condition.
I guess it is not much less hardy as a dunstan citrumelo
Three meters beside and away of the house.

Can anybody say something to the fruit quality of ichangquat?
Mine is from eisenhut, not 6-7-2.

According the keraji, I have one growing well protected growing together with a thomasville citrangequat at the south western wall of my house.

That is also my experience.
Do you protect your tree when there is colder weather forcast?

Seeds of a seedless yuzu! 

Here is a picture of mine. Unfortunately no fruits this year.

For the first time I have read about paw paws in german forums maybe at least 10 years ago.
At that time, I could not find a supplier here in Switzerland. After searching hard, I found a nursary in eastern austria from where I could order two plants.

My country is not big, therefore many of my plants come from many different countries.
