Common Pests & Diseases

Rhododendron Atlanticum is relatively pest and disease resistant. However, it may occasionally be affected by the following:

• Lace Bugs: These small, winged insects may cause yellow stippling on the leaves. To control lace bugs, spray the plant with a strong stream of water or use an insecticidal soap.
• Root Rot: Overwatering or poorly drained soil can lead to root rot, which can cause the plant to wilt and die. To prevent root rot, ensure that the soil is well-drained and avoid overwatering.
