Cause of peony problem finally identified
The society says the microscopic pests are hard to spot until damage appears, and recommends early-spring treatments and fall cleanup to limit infestations.
- The Minnesota Peony Society identified microscopic eriophyid mites as the cause of peony leaf deformity, which manifests as wavy, curled leaves with reddish edges affecting individual stems or entire plants.
- Gardeners previously suspected herbicide drift caused the distorted foliage, but The Minnesota Society confirms eriophyid mites are responsible even without chemical exposure.
- Because these mites are microscopic, their presence goes unnoticed until leaf symptoms appear, with infestations sometimes affecting a single stem or occasionally the entire peony plant.
- The Peony Society recommends horticultural oil, neem oil, and insecticidal soap for control, while advising removal and disposal of foliage after fall frost to reduce overwintering populations.
- Control products are most effective when applied in early spring as peony stems emerge and leaves unfold, before mites establish populations.
