Treetec™ tree care system

• Applied research to support optimal tree development in planters
• Treetec™ Basic: oxygen circulation system, thermal insulation and root-ball fixation to promote healthy growth
• Treetec™ Bottom Up: water reservoir at the planter base with capillary columns for improved water distribution and reduced irrigation frequency
• Biodegradable capillary columns: designed to degrade progressively while roots colonise the structure, enhancing water and oxygen retention over time
