Hi all,
After the umpteenth burglary at "casa bleu", I need to resort to some stiff security steps.

I want to stop "yoofs" climbing onto my garage flat roof, and sneaking into the back yard, where they proceed to help themselves to my hard earned money/boot my doggy/steal my cars. I am not really keen on razor wire and don't want to reapply for my firearms license at this moment.

I want to plant some thorny barriers. And was thinking of a double row of Hawthorn hedging around the rear of the garage for people to castrate themselved by jumping into, and some kind of a pot-borne climbing rose trailing over the front of the garage, and along the longer side.

Would Hawthorn (C. Monogyna?) damage walls or foundations if grown slap up againt the rear wall of the garage? How about common Gorse? My garden soil is moist, clay like (Liverpool Weather) and partially shaded.

Also could you suggest a very thorny, fast growing evergreen climber I could grow over the front door/roofline of the garage and along one of the longer sides? The longer side needs to be covered by a climber that is happy to grow from a pot, if possble, otherwise I will need to take off a pavement slab and plant it in the ground right up against the wall of the house.

I would like a solution that is kind and welcoming to the birdies and beasties that visit my garden at this moment, something that offers them food and protection would be especially nice.

Is there a thorny barrier that is evergreen/non deciduous that I can stick along the fence as well? Hopefully with a bird and building friendly characteristic?
