Diagnosing Holly Leaf Spots and Pruning Guidelines

Yellow Leaves + Dark Spots = Multiple Possible Causes

Nutrient imbalances, fungal leaf spots, or physiological disorders can all cause yellowing with dark spots on holly. A close-up photo of the spots is needed for accurate ID.

Pruning Basics

• Timing: After flowering (if ornamental) or late winter for non-showy types.
• Amount: Never remove more than ⅓ of branch length in one season.
• Technique: Cut back to a lateral branch or bud.

Over-pruning (the “butcher” approach) can kill or severely weaken shrubs.
