Troubleshooting
Doerfler's Thyme problems — and how to fix them
Doerfler's Thyme (Thymus doerfleri) 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.
Crown and stem rot
The most common issue, caused by excessive moisture or heavy, poorly drained soil. Ensure very sharp drainage and avoid watering the foliage directly. Remove rotted stems promptly.
Legginess after flowering
Without trimming, plants become woody and sparse. Lightly shear back by one-third immediately after flowering to encourage fresh basal growth; do not cut into old hard wood.
Winter wet damage
In high-rainfall climates, protect with a pane of glass or place in an alpine house over winter. Wet cold, not frost alone, is the primary cause of winter losses.
