Mountain Lemon Thyme problems — and how to fix them
Mountain Lemon Thyme (Thymus nervosus) 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.
Winter crown rot
High rainfall combined with poor drainage causes the crown and lower stems to rot over winter. A grit collar around the base and a south-facing aspect are the most effective preventive measures.
Woody die-back
Without annual post-flowering trimming the centre becomes bare wood that will not regenerate. Clip back by up to one-third after flowers fade, cutting into green wood only.
