What's eating my redvein enkianthus?

Redvein enkianthus, an acid-loving shrub related to rhododendrons, shares many of the same pests. Vine weevil larvae damage roots, while adult weevils notch leaf margins. Lace bugs and spider mites can disfigure foliage in hot summers. Slugs attack soft new growth at the base in spring.

Adults cut distinctive U-shaped notches around leaf margins; larvae eat roots causing sudden wilting Apply nematodes (Steinernema kraussei) to soil in late summer; use vine weevil traps for adults; check container compost for C-shaped white grubs

Pale, bleached stippling on upper leaf surface; brown excrement spots on undersides Spray undersides with insecticidal soap or neem oil; place plants in shadier positions to reduce stress

Fine pale mottling on foliage; fine webbing on undersides during dry spells Mist foliage; apply miticide or insecticidal soap to undersides; avoid dry, hot, sheltered microclimates
