Hirsute Slipper Orchid problems — and how to fix them
Hirsute Slipper Orchid (Paphiopedilum hirsutissimum) 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 and stem rot from excess winter moisture
The winter rest requirement is strict. Continuing to water normally during dormancy causes fungal rot at the base of growths. Reduce to near-dry misting only from late November and resume watering only when new growth emerges in late winter.
Leaf browning and tip burn
Caused by fluoride or salt accumulation from tap water or overfertilizing. Use rainwater or reverse-osmosis water, fertilize at dilute rates, and flush the pot with plain water monthly to leach out salt deposits.
No flowering
This species requires a genuine cool, dry rest to initiate flower spikes. Without winter temperatures dropping to 4–10°C and reduced watering, plants grow vegetatively but fail to bloom. An unheated but frost-free spare room or greenhouse works well.
