ULPT: Where to get thorns or other ground deterent?

Posted by HOW_I_MET_YO_MAMA@reddit | UnethicalLifeProTips | View on Reddit | 49 comments

There is a plant thief in my neighbourhood who steals my plants. He/she has to walk over my front grass to do so. What can I put on the grass to stop them from doing this?

Maybe some big-ass thorns.

I am strictly not allowed to put up fencing or bollards or any visual blockage, according to the hoa rules. So it has to be something invisible like thorns.

Any advice on where to buy such things or similar would be greatly appreciated.

Note: I have no pets or kids and no one else has any reason to walk on this particular patch of grass, so no innocents should be affected.

Note 2: I have no camera/cctv and no budget to set one up to determine the culprit.
