Learn to Protect Your Box Hedging
Box hedging is an important part of British garden culture. Understanding the signs of box tree caterpillar activity, knowing when to inspect and learning how damage develops can help gardeners and grounds teams respond more effectively.
Explore our guides, frequently asked questions and developing library of case studies to learn more about identifying, monitoring and managing threats to Buxus.
Why education matters
Knowledge is the first line of defence
Box tree caterpillar can spread quickly through established box hedging and topiary. Early awareness, regular inspection and accurate identification can make it easier to recognise activity before extensive damage develops.
XenGuard’s Learn section is designed to give gardeners, estates, hotels, landscapers and grounds teams a clear place to understand the problem, explore real-world examples and find answers to common questions.

Protecting an important part of British gardens

The XenGuard education library will continue to grow with new guidance, case studies and seasonal information.
