Troubleshooting
Noble Cymbidium problems — and how to fix them
Noble Cymbidium (Cymbidium goeringii) 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.
Refusing to flower
Almost always too little light or, more often, no proper cold winter rest. Give it a genuinely cold, bright winter near freezing-tolerant temperatures to initiate its spring blooms.
Brown, scorched leaf tips
Direct sun, dry air, or fertiliser salts burn the fine foliage. Move to bright shade, flush salts regularly, and keep humidity and airflow up; this species is sensitive to over-feeding.
Rot in a dense or wet pot
Heavy, water-retentive media rot the fine roots. Use a gritty, instantly draining terrestrial mix in a tall pot and keep only lightly moist, especially in cold weather.
Stunted, weak growth
Kept too warm year-round it declines without its cold rest. Give it a cool winter and fresh airflow; it is not a warm-room orchid and resents central heating.
