Hi all,
I can remember a few years ago a crime prevention officer
mentioning
so called deterrent bushes that you can place around your garden or points
of possible entry - not doors :-) Can any of you recommend some thorny
plants/bushes fit for this purpose - is there any limit to the height that
they will grow or do they reach a natural peak ? Apologies for sounding a
bit daft but, as you can see, I do not know a lot about this subject.

Cheers,
Keith
