I purchased this Schefflera Compacta online about a week ago.

When I took it out of the delivery box, some leaves had fallen to the bottom already but I thought it would be fine, I placed it one meter away from a NW facing window and noticed as I carried it brown leaves were falling. I haven't watered it in a week as I wanted to give it a chance to acclimate to its new environment and then start watering it every other week as it's winter here.

Yesterday I noticed brown spots all over the leaves that come from one of the stems which is effectively rotting or suffering from some kind of fungus.

I have now moved it to the bathroom for a bit of humidity, but I am not sure what to do as it was probably rotten from the moment it was sent to me by a plant shop which already sent me a broken Pilea. The roots seem fine.

Should I water it? Should I wait?

Please help !
