Troubleshooting
Spider Orchid problems — and how to fix them
Spider Orchid (Brassia verrucosa) 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.
Black, mushy roots or bulbs
Root rot from a soggy, broken-down mix or overwatering. Use fast-draining bark, water only when it dries, and repot if the medium has gone to compost.
Pleated, accordion-like new leaves
A sign of insufficient water or humidity during leaf development. Keep moisture and humidity steady through active growth to allow leaves to expand smoothly.
Reluctance to bloom
Usually too little light or no winter rest. Brighten the position and give cooler, drier conditions in winter to trigger spring flower spikes.
Spider mites and scale
Mites cause fine stippling in dry air; scale appears as brown bumps on bulbs. Raise humidity, improve airflow, and treat with horticultural oil or insecticidal soap.
