Troubleshooting
Browning Coelogyne problems — and how to fix them
Browning Coelogyne (Coelogyne fuscescens) 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.
Recovery slowdown after repotting
Coelogyne fuscescens is unusually sensitive to root disturbance. After any repotting or division it can take 2–3 years to return to peak flowering. Avoid repotting unless the substrate has fully decomposed or the plant is severely pot-bound; prefer top-dressing or removing only dead material at the margins.
Leaf-tip browning
Brown leaf tips most commonly result from low humidity (below 60%) during the growing season, inconsistent watering causing intermittent drought stress, or salt accumulation from fertiliser. Raise humidity, water more consistently, and flush the medium regularly with plain water.
Crown rot from poor air circulation
High humidity combined with stagnant air can allow fungal pathogens to settle in the new growths. Always maintain gentle air movement around the plant and avoid wetting the crown in cool, cloudy conditions.
