Soon I am going to do some grafting of green (this year's growth) to
green material, about 3 mm in diameter. I did not succeed in this last

I found difficult was to bind the two pieces together. So this year I
am thinking of experimenting with heat-shrink tubing and I wonder if
there is any experience of this out there or any thoughts.

Try Googling for self-amalgamating tape.

Very difficult to cut off when you need to.

But that's nothing to the difficulty of wrapping it round a graft
without doing it harm. It has to be stretched up to double its supplied
length before the contraction is sufficient to meld the surfaces. (I use
it a lot on electrical joints, so I've tried it on grafts...)
