Troubleshooting
Camphor Thyme problems — and how to fix them
Camphor Thyme (Thymus camphoratus) 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 rot in wet conditions
The primary cause of death — winter rainfall on heavy or clay soil causes rapid crown collapse. Plant in raised beds, on slopes, or in containers with excellent drainage; mulch with grit rather than organic material.
Frost damage on wet stems
While moderately frost-hardy when dry, wet stems are damaged at temperatures below -5°C. In cold, wet regions, move containerised plants to a frost-free, well-ventilated cold frame over winter.
Woody dieback
Like all thymes, the plant becomes very woody without regular pruning. Trim lightly after flowering, removing spent flower stems and up to 20% of growth to maintain a dense, leafy mound.
