Here's the answer to your gardening question...

You asked:

What are the white blobs on my hydrangea stems?

Our Advice:

This is a type of scale insect, which sucks sap from the stems and leaves. High populations can severely weaken your plant. We suggest you control this pest with spray of Sprayday Bayer Greenfly Killer'>Greenfly Killer from SBM/Bayer, or Resolva Bug Killer from Westland.
