Q: Our HOA is trying to keep people from climbing over the fence to get through our property. Can you give us the names of some thorny, sticky, prickly shrubs to make it unappealing?
A: Chinese holly, barberry, Knock Out rose, pyracantha, mahonia, or yucca are guaranteed to give a fence climber pause. Before using them, consider if you’ll need to prune each year. None of these are small shrubs. Their size can be controlled with regular pruning but plan on wearing protective gear when you do it.
