I have a lot of trouble with next door's youths sitting on and jumping over the dividing wall at the front of the house, it edges my driveway.
I did try window boxes on a small stretch last year but together with my other pots and tubs they take too much time and effort with the watering. I would need at least ten boxes to cover the whole length and they could get stolen unless fixed in some way.
Any ideas what I can put on top of the coping, I believe broken bottles would be illegal.
I have found the following but would it deter 18yr olds.
