The concept of Defensive Planting is simple, but highly effective.
A dozen varieties of very prickly plants are shown below. They have been chosen for their impenetrability and attractiveness.
Plant them under vulnerable windows and allow to grow to sill height. You can also plant them around your boundary. Intruders will be unable to pass through (or over) the plants without shredding themselves. (Very painful)
