Troubleshooting
Glasswort problems — and how to fix them
Glasswort (Salicornia europaea) 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.
Failure to establish in low-salinity soil
Glasswort is an obligate halophyte and will rapidly decline in ordinary garden soil; always grow in salt-amended or coastal sandy media and do not use peat-based potting mixes.
Slug and snail damage
Succulent stems are attractive to slugs, especially in the wet, coastal conditions the plant prefers; use iron-phosphate pellets or copper barriers to protect seedlings.
Prevent glasswort problems before they start
Most glasswort issues are care-mismatch, not bad luck. Dial in the basics:
