I think 1-year is a good idea, Clark.
People setting bark grafts or something with a great deal of push should definitely leave on their tape for a full year. And for certain at year two a solid stake needs to be added to keep that graft's growth from blowing out. I have a hickory putting on three feet of growth this year from a scion the size of a pencil two-years ago when it was grafted. No stake and that means trouble. Plus you're keeping the 'excurrent' form. Probably the wrong word but I have an oak that grows excurrent so a nice & straight trunk is a must with this radical growth that occurs when a large tree and a small scion intersect, lol. That was a bunch of babble....
Even bench grafts onto 1/4" caliper stock I see absolutely good reason to leave on the tape or rubber bands and to reapply rubber bands when they fall apart from sun. I reapply budding strips all the time.
I got into the habit with conifers to remove the bud strips in July. I realize now I am reapplying bud strips on most of my grafts now-a-days until the following year. Took me far too long to get my point across but, I did it darn it all.
Oh and I just started using electricians tape this yar. I love it.
@NuttingBumpus good comments.
