Scale on Golden Euonymus: Treat or Replace?

Assessing the Infestation

Scale insects are the most damaging pest on golden euonymus. If the shrub is encrusted from top to bottom, eradication can take years and the plant may never fully recover its shape.

When to Replace

If you don’t have a strong attachment to the specific plant, removal and replacement with a different, scale-resistant shrub is often the most practical choice. Tea scale, the common species on euonymus, prefers this host and is less likely to jump to unrelated plants.

If You Want to Save It

A soil drench of Bayer Advanced Tree & Shrub Insect Control (imidacloprid) moves systemically through the plant, killing scale as they feed. Follow label directions carefully; the product is not inexpensive but can be effective when applied correctly.
