Troubleshooting
Shiny Thyme problems — and how to fix them
Shiny Thyme (Thymus nitidus) 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.
Root rot and crown collapse
Poor drainage or overwatering causes rapid collapse, especially in winter. Grow in raised beds or containers with a thick gravel drainage layer. This species is less forgiving of moisture than common thyme.
Woody die-back at centre
Like most thymes, the centre becomes woody with age. Trim lightly after flowering each year to prevent this. Do not cut into old wood — propagate fresh plants every 4 years.
Slugs and snails on young shoots
Emerging spring shoots in damp climates can attract slug damage. Apply grit mulch around the base; this deters slugs and improves drainage simultaneously.
