I have some long pieces (15 ft) of Boston Ivy.

Can I just cut it off before where the tiny trailing roots go into the ground at some point and then replant it elsewhere?

I know I can take short clipping, but I really want larger pieces. I can't dig up the entire thing from the source as it is where all my Boston Ivy starts in the yard and I'd ruin it all.

The place I'd like to cut it off is hard wood, maybe 1/4" thick. I'm worried that the small trailing roots won't sustain a 15 foot long plant.
