Troubleshooting
Bristly Lepanthes problems — and how to fix them
Bristly Lepanthes (Lepanthes horrida) 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.
Mealybugs in sheaths
The dense bristly sheaths provide ideal hiding spots for mealybugs. Inspect sheaths regularly; treat early infestations with 70% isopropyl alcohol on a swab or a systemic insecticide.
Root rot from stagnant moisture
Constant moisture without airflow creates anaerobic conditions. Ensure some air movement reaches the root zone even in high-humidity setups — use a small fan on a timer.
Sudden leaf drop after repotting
Stress from root disturbance can cause rapid defoliation. Minimise root handling, repot in late winter before new growth, and keep conditions stable for 4–6 weeks post-repotting.
