I think attaching insulation to the wardrobe back can't do any harm and

It can. Apart from being work unlikely to succeed it can trap
condensation, worsening mould.

Worked every time I've done it. Polystyrene insulation is closed cell
so it can't "trap" condensation. The problem isn't water dripping from
walls but warm air cooling as it gets between the colder wall and
warmer wardrobe. This creates a slight film of condensation which is
enough to allow mould growth either on the wall or the wardrobe. You
commonly see this occurring in a room used to dry clothes or a
North/East facing corner of a room which tends to be cooler than
others. If clothes are dried in the room the answer is to get a
proper dehumidifier in the room and run it while clothes are drying
and for a time afterwards (It also speeds up the clothes drying).


I was surprised that the OP mentioned that there is mould on the
wardrobe, but not on the wall. Any explanations?

I rather wonder if damp clothes have been hung. The door is fairly close
fitting so the air can't circulate. There is grey powdery mould on the
wall side of the hardboard and discolouration on the white finished
inside.
