What are the white blobs on my hydrangea leaves?
Our Advice
Your plant is being attacked by a type of scale insect, which sucks sap from the stems and leaves of plants. If the populations of these pests become very high, the plant can become so weakened it may die. We suggest you control this pest with spray of Sprayday Bayer Greenfly Killer'>Greenfly Killer from SBM/Bayer, or Bug Clear Ultra from Scott's.
