While landscaping can contribute to the aesthetics of a building, if not carefully controlled and thoughtfully designed, it can also provide lots of cover for those with a criminal intent. Evaluate the location and height of plants and shrubs by doors, windows and walkways with security in mind and keep them pruned back. Consider planting “protective plants” which have thorns (i.e. barberry, rose bushes, etc.) as an additional means to keep criminals uncomfortably away.
