Chinese meadow-rue is susceptible to aphids, which can cause yellowing and distortion of leaves. To prevent aphid infestations, regular inspection and the application of insecticidal soap can be effective. Another common pest is spider mites, which can cause stippling and webbing on the plant. These pests thrive in dry conditions, so maintaining proper humidity levels can help prevent infestations. Fungal diseases like powdery mildew can also affect Chinese meadow-rue, leading to a white powdery coating on leaves. To prevent powdery mildew, ensure good air circulation around the plant and avoid overhead watering. Root rot can occur if the plant is overwatered or planted in poorly-draining soil, causing the plant to wilt and decline. To prevent root rot, plant Chinese meadow-rue in well-draining soil and water only when the top inch of soil is dry.
