My husband uses a garden tool that has an extendable handle. It is 2 ft long and extends to full size. It is like a fork on one side and a flat spade(?) on the other. He has been able to help me weed with it. He is able to reach into tight spaces and reach farther than he is able. That might help you
@zuzu get into those prickly places without bending as much and getting nicked?
