Are the grafts growing? If so they dont need re-taping, if not they are probably dead.

Thanks - they're growing. It hasn't come all the way off, so I don't know yet what the graft unions look like.

Scion grafts are usually held by rubber band ....in my case Electrical tap. Parafilm is normally used to seal the scion, not strong enough to hold the actual graft.

Perhaps I'm missing something.
