Long-lipped Tongue Orchid problems — and how to fix them
Long-lipped Tongue Orchid (Serapias vomeracea) 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.
Tuber rot from summer moisture
The most frequent cause of failure in cultivation: tubers kept wet during the summer dormancy period rot rapidly. Lift pot-grown tubers or ensure outdoor beds drain completely dry by June; store or leave them in bone-dry conditions until late September.
Failure to re-emerge after transplanting
Serapias depends on specific soil mycorrhizal fungi; plants moved from their native site or established from nursery stock without these fungi rarely survive more than a year or two. Source from specialist nurseries growing from seed with appropriate mycorrhizal substrate, and do not amend soil with standard compost.
