I bought this diffenbachia summer just gone in my local garden store and it was beautiful.
However I think at some point I have overwatered it as the leaves started browining on the edges and wilting. Also as the weather has got colder the leaves have drooped and basically started to die.
I have read up on diffs not liking cold temps and it has been down to about 12 degrees (C) in the house this winter. There is nobody in during the day so the heating will be off.
Anyway, is there any way i can recover this plant. I have held off watering it as the soil was soaked. The roots appear fine though when i inspected them last week.
Do i need to cut the plant back ???
It is located on a bathroom windowsill near a frosted window which gets light daily.
I've attached some photos also.
P.S. Im a novice here and know next to nothing about houseplants, so be gentle.
