Troubleshooting
Calathea Yellow Fusion problems — and how to fix them
Calathea Yellow Fusion (Goeppertia lietzei 'Yellow Fusion') 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.
Browning leaf edges and tips
Low humidity or hard, fluoridated water hits the thin variegated leaves hardest. Raise humidity and use rainwater or filtered water.
Reverting to plain green
Too little light causes the variegation to fade. Provide brighter indirect light, but never direct sun, to preserve the pattern.
Scorched pale patches
Direct sun burns the cream and yellow zones, which lack protective chlorophyll. Move out of any direct rays.
Spider mites
Dry warm air invites mites, seen as stippling and fine webbing. Rinse the plant, raise humidity and apply insecticidal soap.
