Troubleshooting
Green Dragon problems — and how to fix them
Green Dragon (Arisaema dracontium) 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.
Premature summer dormancy
Green Dragon goes dormant naturally in late summer, but drought or excessive heat accelerates this. Ensure consistent soil moisture through summer; a thick mulch helps retain moisture and moderate soil temperature.
Slug damage to emerging shoots
The emerging shoot in spring is fleshy and highly attractive to slugs and snails. A single growing point destroyed by slugs means no growth that year. Apply organic slug deterrents as shoots break ground in spring.
Seed dispersal becomes weedy
Prolific red berry clusters are eaten and dispersed by birds, and seedlings can appear widely around the garden. Deadhead the berry clusters before they fully ripen if naturalising in a controlled space is not desired.
Prevent green dragon problems before they start
Most green dragon issues are care-mismatch, not bad luck. Dial in the basics:
