Spiked Pleurothallis problems — and how to fix them
Spiked Pleurothallis (Pleurothallis tribuloides) 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.
Root loss from division
Division of tightly caespitose clumps is challenging; even small disturbances can damage fine roots and delay recovery by up to two years. Divide only when the plant has outgrown its container; handle roots with extreme care.
Heat stress
Although more tolerant than cool-growing Masdevallias, sustained temperatures above 28°C cause wilting and reduced flowering. Provide shade, misting, and airflow during hot spells; consider a cool growing room in summer.
Spider mites
Fine webbing and stippled leaves signal spider mite infestation, more common in low-humidity conditions. Raise humidity, increase airflow, and treat with insecticidal soap or dilute neem oil every 5–7 days for three cycles.

Most spiked pleurothallis issues are care-mismatch, not bad luck. Dial in the basics:
