Goat's-beard problems — and how to fix them
Goat's-beard (Tragopogon pratensis) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
Leaves may develop white powdery patches in warm, dry conditions with poor air circulation; improve spacing and avoid overhead watering. Remove and dispose of affected foliage.
Aphid infestation
Colonies of aphids frequently build up on young stems and flower buds in late spring and summer; blast off with water or apply insecticidal soap, and encourage natural predators such as ladybirds.
