Pleione formosana problems — and how to fix them
Pleione formosana (Pleione formosana) 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.
Rotting pseudobulbs over winter
Caused by too much moisture during the cold rest. Keep dormant bulbs cool and nearly dry, watering only enough to stop total shrivelling.
No flowers in spring
Usually an insufficiently cold or short dormancy, or weak summer growth. Give a genuine cold rest near 0-10°C and feed well during the growing season to build strong pseudobulbs.
Snail and slug damage on buds and new growth
Emerging spring buds are a favourite target. Protect plants in frames and gardens with traps or barriers as growth resumes.
Shrivelled or soft pseudobulbs in growth
Either dehydration from underwatering or rot from a soggy mix. Maintain even moisture in an open, fast-draining compost and check roots if softening continues.
