Troubleshooting
Variegated Ground Ivy problems — and how to fix them
Variegated Ground Ivy (Glechoma hederacea 'Variegata') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Reversion to green
Stems occasionally produce fully green shoots lacking the white margin. Remove reverted stems promptly at their base to maintain ornamental variegation and prevent the more vigorous green form from dominating.
Root rot
Overwatering or poorly draining containers cause stems to blacken and collapse at the base. Allow the top of the compost to dry slightly between waterings and ensure pots have drainage holes.
Powdery mildew
White fungal coating on leaves in warm, humid and poorly ventilated conditions. Improve air movement, avoid wetting foliage, and treat with a sulphur-based spray at first appearance.
