About gropod
gropod, invented by Humphrey Herington, founder of Eastern Forest Nursery in Northern NSW, is the product of 30 years of experience in native tree planting and seven years of dedicated research. Humphrey developed gropod to address common challenges in seedling establishment - weed control, browsing animals, unpredictable weather, and budget constraints. This 100% biodegradable tree guard, is designed to boost seedling survival through effective and sustainable protection and user-friendly installation. Today, gropod supports sustainable environmental and land-care projects across Australia's diverse environments.
