Troubleshooting
Turkish Catmint problems — and how to fix them
Turkish Catmint (Nepeta phyllochlamys) 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 from winter wet
The most common cause of plant death in cool, humid climates. Protect with a pane of glass or move containers under cover from late autumn to early spring. A collar of grit around the crown helps deflect moisture.
Botrytis (grey mould)
Grey, furry mould on stems and leaves in damp, cold conditions. Remove infected material promptly. Improve ventilation and reduce humidity. Avoid wetting the crown when watering.
Failure to reflower
Plants may not produce a second flush without deadheading and light trimming. Cut back spent flower stems by one-third immediately after the first bloom to encourage a second flush and maintain a tidy habit.
