How to Solve Coneflower Problems


Coneflowers tend to thrive in the wild but when domesticated and added to our landscape and gardens, they can develop different problems. From overwatering and dried out leaves to aster yellows disease, pinpointing the problem with your coneflowers is the first step to solving it.

Moderately Easy


things you’ll need:
  • Garden shears
  • Organic pest control agent
    1. Assess the soil condition. If your coneflowers are rotting, there may be too much drainage and water seeping into the soil around them. Replant coneflowers in an area that tends to be less moist to save them from rotting.
    2. Trim away rotting plant material with garden shears, being careful not to cut any living material. Getting rid of the rotten plant material will help you control pests, which can also lead to further problems with your coneflowers.
    3. Examine coneflowers as they bloom to identify strange green growth around the seed cones of the flowers. This green growth is aster yellows disease and is relatively common in coneflowers. It is transmitted via pests.
    4. Use an organic pest control agent around the roots, soil and flowers to get pest problems under control.
    5. Add organic mulch, like dead leaves, around the coneflowers before winter.
    6. Monitor your coneflowers as they emerge in the next season. Generally, coneflowers will outgrow aster yellows disease in one to two seasons.
