What's eating my crested iris?

Crested Iris (Iris cristata) is a low-growing woodland native that attracts aphids and may be targeted by iris borers, though borer damage is less common than in tall bearded types. Slugs readily damage the low foliage. Deer will browse it. Spider mites can cause problems in hot, dry conditions.

Ragged holes in low-growing foliage; seedlings and new shoots consumed at soil level; slime trails visible Apply iron phosphate pellets; hand-pick at dusk; avoid thick mulch directly around the crowns

Clusters on new growth and flower stems; honeydew deposits and associated sooty mold; distorted leaves Spray with water or insecticidal soap; introduce aphid predators; treat persistent infestations with neem oil

Foliage and flowers browsed to the ground, especially in woodland garden settings Use deer repellent sprays; fence small plantings; plant among deer-resistant companion plants
