Leaf scorch (marginal leaf necrosis)

Viburnum or linden shows marginal leaf browning and necrosis from salt drift, excessive fertilizer, or environmental stress. Herbicide damage is a common cause. Avoid herbicide drift near susceptible plantings, provide proper watering and nutrition, use deep, rich soil, and check for trunk damage. Recovery is slow but steady.

Management depends on catching it early. Scout susceptible plants regularly and remove affected tissue before the pathogen can spread. Improve growing conditions by addressing drainage, spacing, and irrigation practices. For persistent or severe cases, contact your local Master Gardener program or Extension office for treatment options specific to your host plants.
