Beech Leaf Disease is Spreading
Beech Leaf Disease (BLD) has become a growing concern in our region, with our arborists observing high concentrations of affected beech trees along the Main Line. Caused by the microscopic nematode Litylenchus crenatae ssp. mccannii, BLD is a fatal disease impacting all beech species, including European cultivars.
The American beech (Fagus grandifolia), known for its smooth, gray bark and dense green canopy, is a hallmark of native eastern forests. However, BLD threatens these iconic trees. Early symptoms include distinct dark green banding between leaf veins, followed by distorted, cupped, or curled leaves that shed prematurely. In severe cases, buds die, leading to branch dieback and tree death within 3–7 years, depending on the tree’s vigor.
The good news? There’s still time to protect your beech trees! Our team offers effective solutions to manage and mitigate BLD.
