Troubleshooting
Grass-leaf Disa problems — and how to fix them
Grass-leaf Disa (Disa graminifolia) 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.
Salt sensitivity
Tap water minerals rapidly cause root burn and leaf tip browning. Always use only rainwater or purified water.
Crown rot
Fungal infection at the base of the leaves from stagnant, warm, humid conditions. Ensure cool temperatures with good airflow.
Spider mites
Grassy foliage in warm, dry conditions is vulnerable. Maintain high humidity and treat with insecticidal soap at first sign.
Over-fertilising
Even small amounts of fertiliser can burn the sensitive roots. If in doubt, do not feed at all and rely on rainwater trace nutrients.
Heat stress
Disa graminifolia cannot tolerate prolonged temperatures above 25°C. Move to a cool, shaded position in summer heat.
