Testing a second grafting with dormant scion (P2)

At the beginning of March, a first check was done for a second grafting to the same tree with a dormant scion, which took place at the end of August.
At the second grafting too, when we opened the protective tape, the welding seemed to succeed.
At the beginning of April, when the vegetation will start, it will be seen if the grafting has succeeded 100%.
