What's eating my compacta holly?
Holly leafminer (Phytomyza ilicicola)
Signs: Yellow-brown winding or blotch mines inside leaves, disfiguring foliage by summer

Southern red mite (Oligonychus ilicis)
Signs: Bronzed, stippled upper leaf surfaces; worst in spring and autumn during cool periods
Control: Spray horticultural oil in early spring before populations explode; use miticide if populations are severe
Holly scale (Dynaspidiotus britannicus)
Signs: White or grey encrusted bumps on stems and leaves; yellowing foliage and stunted growth
Control: Scrub light infestations off with a soft brush; apply horticultural oil in late spring when crawlers are active
Black vine weevil (Otiorhynchus sulcatus)
Signs: Scalloped notches on leaf margins at night from adults; root damage from larvae causing wilting
Control: Apply beneficial nematodes to soil in late summer; check under mulch for C-shaped larvae and remove by hand
