Troubleshooting
Sea Bindweed problems — and how to fix them
Sea Bindweed (Calystegia soldanella) 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
Sea bindweed is notoriously difficult to transplant or establish outside coastal sand — it almost always fails in ordinary garden soil; use pure horticultural sand or fine grit with no organic matter and do not move plants once established.
Slugs and snails
The fleshy leaves and young rhizome tips are attractive to slugs and snails, which can destroy emerging shoots; use pellets (slug-gone/ferric phosphate) around new plantings, particularly in damp weather.

Most sea bindweed issues are care-mismatch, not bad luck. Dial in the basics:
