Root defects in nursery tree stock are ticking time bombs. Circling roots, girdling collars, and pot-bound kinks—once buried—can go unnoticed for years until decline sets in. But they are preventable. AS 2303, the Australian Standard for tree stock, requires inspection of root systems before planting. It ensures root systems are structurally sound and correctly oriented, and it mandates rejection of defective trees like these. Healthy urban forests start with healthy roots. Your clients will thank you for insisting on AS 2303-compliant stock. And your city? It deserves trees that thrive, not struggle. Don’t bury a problem. Plant a solution—with roots worth growing.
