I know exactly what you mean. Between the roses, raspberries, and devil's club, I could make a huge pile (what do I mean, could...I do) every summer. I try to throw them all under one of the large stands of devil's club...that way I'll know to be careful and not grab them by accident some year down the way.

Throw them in the bush across the road. :>

We live out of town so I just toss rose canes etc on the burn pile and burn them..Jean

I just toss them in the bush on a pile of other things that can not be composted and let critters live under it.

I wove some through my fence for decorative purposes. You can't use barbed wire to keep kids out in the city.
