The Tree Anchor Wire Fixing System is a discreet, underground tree anchoring kit designed to securely stabilise rootballed and container-grown trees in both soft and compacted soils. Used widely in urban landscaping schemes, housing developments, public realm installations, parks, and highway planting projects, this system ensures trees establish successfully while minimising movement from wind or human interference.
It’s a proven method for supporting trees without staking above ground, preserving the visual aesthetics of open spaces and reducing trip hazards. The galvanised steel ground anchors and tensioned wire system provide long-lasting performance, while rubber rootball protectors ensure the rootball remains intact and protected during establishment.
