How Can I Tell If My Walnut Tree Is Diseased Or Dying?

Wondering how to tell if your walnut tree is diseased or dying is a common concern among property owners. Mature trees like walnuts are a valuable part of any landscape, and when their health declines, it can affect the beauty, safety, and environmental value of your property. Whether you're dealing with yellowing leaves, cracked bark, or bare branches, knowing the warning signs early can help you make the right call about removal, pruning, or treatment.

How can I tell if my walnut tree is diseased or dying?

Signs of a diseased or dying walnut tree typically begin with visual symptoms such as wilting, browning leaves, or early leaf drop. You might also notice the tree struggling to produce healthy nuts or see black lesions on the trunk and branches—common indicators of common fungal diseases like thousand cankers or anthracnose. If the bark is splitting, limbs are brittle, or fungal growth appears at the base, it could point to root rot or other internal decay that compromises the structural integrity of the tree.

Another key sign is reduced canopy growth. If your walnut tree looks sparse compared to previous seasons, or if branches are dying off one by one, there may be internal damage or insect infestation, such as from bark beetles. A certified tree professional can assess the health of the tree and advise whether it's treatable or needs to be safely removed to avoid risks to surrounding structures and vegetation.
