Introduction
Coneflowers, also known as Echinacea, are popular wildflowers that add beauty and color to many gardens. They are known for their long blooming period, from midsummer through fall, and their resistance to most pests and diseases. However, there are a few common issues that can affect coneflowers, which we will explore in this article.
Coneflower Pests
The most common insect pests that affect coneflowers include:
- Sweet potato whiteflies: These pests feed on the undersides of leaves, causing yellowing, shredding, and the growth of black sooty mold.
- Aphids: Aphids suck the nutrients from plants, which can quickly overwhelm and kill them.
- Japanese beetles: These beetles feed in groups, starting at the top of plants and working their way down, destroying foliage and flowers.
- Eriophyid mites: These mites live inside flower buds, causing stunted growth and distorted flowers.
