Troubleshooting
Dieffenbachia Tropic Marianne problems — and how to fix them
Dieffenbachia Tropic Marianne (Dieffenbachia 'Tropic Marianne') 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.
Variegation reverting to green
Too little light reduces the pale colouring; move to brighter, indirect light to maintain the ivory leaves.
Yellowing lower leaves
Usually overwatering or natural ageing; let the soil surface dry between waterings and check drainage.
Brown leaf edges
Low humidity, dry soil, or fertiliser-salt buildup; raise humidity, water consistently and flush the soil occasionally.
Soft, mushy stem base
Stem rot from cold, soggy conditions; reduce watering, keep warm, and propagate healthy cane tops if the base is failing.
