Cardboard Quikcrete forms

I have a few questions about cardboard tubing 8" diameter.

I need to make a piece about 20" long but the post around which I want to add concrete is already in place and I cannot slide it down from above due to another obstacle.

Can I cut the tube longitudinally, pry it open and place around the post, tape it back together (or tie it with thin wires)? Any reason I should avoid doing this?

Also, how long do you keep the tube before removing it? With food form you can basically gently remove it after a day or so, with this I assume it's difficult to remove it like wood form, do you cut it up and peel it off, or do you just let it disintegrate as you mist the concrete for days and eventually it will break down enough to remove easily?

Forms are commonly taped together to make taller forms. I would use a good quality duct tape to put the form back together. You can remove the form after a few days but I just let them fall apart on their own.
