FNGLA Horticulture Landscape Maintenance Practice Test

When structural concerns linger after pruning, a professional assessment is needed because pruning alone may not fix underlying defects. An arborist can evaluate the tree’s stability and recognize weak unions, cracks, decay, included bark, cavities, or root issues that pruning can’t repair. They’ll determine the real risk of failure under wind or loading and propose appropriate actions, which might include cabling or bracing to support weak parts, selective pruning to reduce stress, or removal if the tree poses an ongoing safety hazard. This approach focuses on safety and long-term health, following established standards and best practices. Other options don’t address the underlying structural risk: pruning more aggressively can remove critical support and create new hazards, waiting a year may allow the risk to increase, and planting a replacement doesn’t mitigate the immediate danger or structural flaws.
