Hirtz's Lepanthes problems — and how to fix them
Hirtz's Lepanthes (Lepanthes hirtzii) 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.
Rapid desiccation
Without pseudobulbs, any interruption to humidity or watering causes immediate leaf collapse. Enclose in a humid case — even 30 minutes of dry air can be fatal to a small mount.
Fungal rot at ramicaul bases
The dense mat habit traps moisture at stem bases. Ensure gentle air circulation within the enclosure (a small 5 V fan is sufficient) to discourage Botrytis and bacterial soft rot.
Heat stress
Temperatures above 22 °C for more than a few hours cause leaf yellowing and collapse. Use an active cooling device (aquarium chiller, air conditioning, or basement environment) in summer.
