Troubleshooting
Inch Plant problems — and how to fix them
Inch Plant (Tradescantia fluminensis) 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.
Leggy, sparse growth
Stems stretch and bare out in low light. Move to brighter indirect light and pinch the tips regularly to force bushier, fuller growth.
Fading colour or reverting to green
Variegated forms lose their pink/cream tones in insufficient light or with excess fertiliser. Increase light and ease off feeding to restore variegation.
Root rot (brown or black leaves)
Whole leaves turning brown or black usually signals overwatering. Let the top half of the soil dry between waterings and ensure the pot drains freely.
Crispy brown leaf tips
Caused by underwatering or very dry air. Water more consistently and raise local humidity with a pebble tray or nearby humidifier.
Spider mites and sap-sucking pests
Watch for fine webbing and stippling from spider mites, plus aphids, mealybugs and fungus gnats. Rinse foliage and treat with insecticidal soap or neem.
Scorched patches on leaves
Dry brown spots can be sunburn from harsh direct sun. Move to filtered light or diffuse it with a sheer curtain.
