# Sun burn or watering issue? My Diffenbachia is in the south corner of…

Sun burn or watering issue? My Diffenbachia is in the south corner of a southwest facing sunroom. It does get some direct sun in the morning and afternoon. I noticed this leaf going limp two days ago when I last watered it, now it's looking brownish yellow.

If it were sunburn I’d expect more leaves to show signs. How far down the plant is this leaf? If it’s one of the oldest leaves it may just be its time to fall off.

Also, I think you may have a dieffenbachia camouflage and not an Amy. I don’t think care is much different between the two tho

This looks more like a watering issue—sunburn typically causes the leaves to turn a crispy brown.

If it’s just one leaf, remove it. It’s natural for older leaves to die off occasionally.
