Pest identification

What's eating my japanese plum yew?

Deer

Signs: Foliage and stems heavily browsed, especially in winter when other food is scarce; can severely disfigure or kill young plants

Control: Deer netting or wire cage around young plants; deer repellent sprays reapplied after rain; established large shrubs tolerate browsing better

Scale insects

Signs: Brown or whitish bumps on stems; yellowing needles; sooty mold on honeydew deposits in sheltered sites

Control: Apply horticultural oil in late winter; follow with insecticidal soap spray in early summer; improve air circulation if plants are crowded

Black vine weevil (Otiorhynchus sulcatus)

Signs: Characteristic U-shaped notches on leaf margins at night (adult); larvae in soil girdle roots causing wilting and dieback

Control: Apply beneficial nematodes (Steinernema kraussei) to moist soil in late summer for larval control; use sticky traps or hand-pick adults at night

Japanese Plum Yew pests — FAQ

What is eating my japanese plum yew?

Japanese Plum Yew (Cephalotaxus harringtonia) is notably pest-resistant. Mealybugs and scale can infest plants in sheltered spots, and deer — unlike with true yews — will readily browse this shrub. Root weevils may notch leaf margins. The greatest pest pressure in most gardens comes from deer, making it a paradox: tough for insects, vulnerable to browsing.
