Q.Rubber tree is dropping
My rubber tree was growing well for the last few months since I got it. However, I went overseas for 3 weeks and since coming back it’s been dropping, leaves and stem. I thought it may be because it was very cold whilst I was away (Melbourne winter) so moved it to a spot with more sun.
I checked the soil and watered it as the soil was very dry. It still hasn’t come back to life. It’s still winter here in Melbourne and generally pretty cold so I wonder if that’s affecting it. And clue on how to help it?

The cold exposure and lack of moisture certainly would make your plant droop.
If the plant was in this position for a long period, it may not grow upright again.
You could take cuttings and propagate some new plants from this plant.
