Troubleshooting
Golden Japanese Sweet Flag problems — and how to fix them
Golden Japanese 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.
Brown leaf tips from dry air or drought
The most common issue indoors. Caused by low humidity, underwatering, or draughts. Trim brown tips with scissors at an angle and ensure the pot never dries out; stand in a pebble tray of water.
Variegation fading to green
Insufficient light causes the gold pigment to fade. Move to a brighter position with indirect light. Occasionally, plain green reversions should be cut out at the base to maintain colour.
Root rot in stagnant anaerobic soil
Paradoxically, while the plant loves water, stagnant pots with no drainage can turn anaerobic. Use an unglazed pot or a container with drainage holes standing in a shallow water tray to maintain aerobic wet conditions.
