Likely causes
Holly leaf miner
Most likelyHow to tell: You will see winding, snake like trails or blotches inside the leaf tissue. These are caused by larvae tunneling between the leaf layers.
What to do: Prune off and destroy the infested leaves to stop the cycle. You can apply a systemic insecticide in early spring to prevent new larvae from entering the leaves.
Scale insects
Most likelyHow to tell: These appear as small, immobile bumps on the stems or leaves. They often leave behind a sticky residue called honeydew.
What to do: Wipe them away with a damp cloth or use a horticultural oil spray. Repeat the treatment every 10 days to catch any newly hatched crawlers.
