Years ago i was getting bothered by dogs wandering through a gap in the wall i'd made to have easier access to the fields beyond. So, reluctantly, i decided to plant a line of dogwood to keep them out. A heap of dead tree branches sufficed to maintain an effective barrier til the hedge grew thick enough to do the job but now it keeps sheep out instead of dogs since the farmer changed from keeping cattle.
A mix of red and green looks good in the morning sun, too, and brings a splash of colour over winter. I'm not a fan of box hedges or those blighted privets that festoon the 'burbs. Still no hedgehogs in this neck of the woods.

Too many dry walls and new fences with gravel boards blocking their path.
