Troubleshooting
Golden Lemon Thyme problems — and how to fix them
Golden Lemon Thyme (Thymus citriodorus 'Aureus') 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 plain green
Shoots that lose the gold variegation and revert to all-green are genetically more vigorous and will outcompete the variegated growth. Remove fully green stems at the base as soon as they appear.
Root rot in wet soil
Soggy or compacted soil causes rapid crown rot, especially in winter. Ensure sharp drainage and, in containers, use a terracotta pot with drainage holes. Never let roots sit in standing water.
Legginess with age
Stems become woody and bare at the centre after 2–3 years without pruning. Cut back by up to one-third after flowering each summer to stimulate bushy basal growth and maintain the mound shape.
