Troubleshooting
Corkscrew Rush problems — and how to fix them
Corkscrew Rush (Juncus effusus 'Spiralis') 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.
Stems straightening and losing curl
Caused by insufficient light. Move the plant to a brighter position — within 30 cm of a bright south or east window. Stems that have straightened will not re-curl; trim them to the base to encourage fresh spiralled growth.
Brown stem tips
The most common complaint, usually caused by dry soil, low humidity, or hard tap water mineral buildup. Switch to rainwater or filtered water, keep the saucer topped up, and increase ambient humidity.
Root rot despite wet soil
Rare but possible if the pot has no drainage and water becomes stagnant and anaerobic. Refresh the water saucer regularly — do not let water sit and become foul-smelling. Choose a pot with at least one drainage hole sat in the saucer.
