2000 Euonymus are some of the most popular and commonplace landscape plants in the home landscape. Their waxy foliage, drought tolerance and diverse growth habit make them inviting when shopping the local garden centers. If your euonymus have a powdery-white substance that looks like snow flakes on them, you have euonymus scale. Here are some tips to help you combat this perennial problem.
Scale insects are highly specialized organisms that come in many shapes, sizes and forms.
The insects feed on plants by inserting their mouth parts into leafy tissue and continually drawing plant juices. Because of this, heavy scale infestations will weaken and kill plants. They insert their mouth parts then lose their legs. Once settled, they produce a scale-like waxy covering and will remain there to feed. The cover protects the delicate, soft-bodied insect beneath and is a barrier against insecticidal materials.
