Testing grafting with dormant scion (P1)

At the beginning of March, a first check was done for grafting with a dormant scion, which took place at the end of August.
At the first graft, 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.
