All scions were grafted on Pereskiopsis stocks and short stock were remained when they were degrafted.
Degrafted in 2012: 22 scions
Degrafted in 2013: 56 scions
All scions were grafted around 1 month old and degrfted when they were 2 years old.
Some of scions degrafted in 2012 pushed pot out and so I repotted in this afternoon.
I also inspected roots during the repotting.
Before repoting, the scion is A. retusu v furfuraceus cv Suguri-cauliflower.
Appearance of roots
I could not see any roots from the scion. All roots came for the short stock.
It seems 18 months of rooting process is not long enough to develop roots from the scion.
I have to wait some more years.
Repotted scion in one-up size pot, 12 cm square
Rooting medium for the scion is scoria.
