In the UK, trees are vulnerable to various diseases that can affect their health and growth, potentially leading to fatal consequences if left untreated.
Recognising these common tree diseases is crucial for tree owners and caretakers to take prompt action in preserving and safeguarding their trees. At DTG Trees and Grounds in Devon, we specialise in all areas of tree surgery, providing advice and care for tree management.
