Troubleshooting
Ogon Sweet Flag problems — and how to fix them
Ogon Sweet Flag (Acorus gramineus 'Ogon') 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.
Fading variegation
Insufficient light is the primary cause of gold fading to pale green. Move to a brighter position with good indirect light.
Brown or crispy tips
Low humidity or dry compost causes tip scorch. Increase watering frequency and place on a humidity tray.
Crown rot
Stagnant water at the base of the stems can cause crown rot despite this plant's love of moisture. Ensure the pot has good drainage and refresh standing water in the tray regularly.
Spider mites
Dry air promotes infestations. Increase humidity, wipe leaves with a damp cloth, and use insecticidal soap if needed.
Yellowing foliage
Can be caused by nutrient depletion in old compost or root crowding. Repot in fresh compost and resume feeding.
