Dieffenbachia Memoria Corsii problems — and how to fix them
Dieffenbachia Memoria Corsii (Dieffenbachia 'Memoria Corsii') 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.
Yellowing lower leaves
Typically overwatering or natural ageing of older leaves. Let the soil dry more between waterings and confirm the pot drains freely.
Brown leaf tips and margins
Caused by dry air or salt and fluoride buildup. Raise humidity, flush the soil and water with filtered or rainwater.
Leggy growth with a bare stem
Too little light or natural maturity. Move to brighter indirect light and prune tall stems to encourage bushier regrowth.
Mealybugs and spider mites
Frequent in dry indoor air, appearing as cottony tufts or fine webbing. Wipe leaves and treat with insecticidal soap or neem oil.
