I water grafting stocks through a year including in winter.
The micro-climate in my greenhouse accepts this situation.
Stocks continue to grow without the dormancy.
The photo is A. retusus v furfuraceus cv Daruma Seiji grafted 1 and a half yeas ago.
It is 2nd winter for these Pereskiopsis stocks.
All leaves fall off in 2nd winter and reducing the growing speed of scions.
I will degraft them in September as usual.
