Troubleshooting
Sublime Slipper Orchid problems — and how to fix them
Sublime Slipper Orchid (Paphiopedilum insigne) 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.
Crown and root rot
Water sitting in the central crown or a sodden, decomposed mix causes blackening rot. Water at the roots, keep the crown dry, and ensure free drainage.
Leaf-tip dieback
Brown, crisping tips signal salt build-up from hard water or fertiliser. Flush the pot with plain low-mineral water monthly and feed at quarter strength.
Failure to flower
This cool-grower often needs a drop to 10-13°C night temperatures in autumn to trigger winter buds; too-warm, dim conditions keep it leafy.
Bleached or scorched leaves
Yellow-green, sunburnt foliage means light is too strong. Move out of direct sun into bright, filtered light.
