Troubleshooting
Red-petal Lepanthes problems — and how to fix them
Red-petal Lepanthes (Lepanthes rubripetala) 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.
Dehydration and leaf crisping
The most common problem in household environments. Leaves curl inward, then crisp at the tips. Mist immediately and increase humidity. Recover by placing in a sealed container with a moist sphagnum mat until turgidity returns. Prevent with a humidity monitor and consistent watering schedule.
Botrytis grey mould
Affects flowers and young growth in stagnant, humid conditions. A gentle fan running continuously inside the growing enclosure prevents this. Remove affected plant parts with sterile scissors and treat with a dilute copper fungicide or hydrogen peroxide solution.
Scale insects
Brown or tan oval bumps on ramicauls and leaf undersides can indicate soft scale. Remove manually with a cotton swab dipped in rubbing alcohol, and follow up with horticultural oil spray. Inspect new acquisitions thoroughly before introducing them to an established collection.
