What is happening to my rubber fig? Rather many leafs are now turning yellow and falling off? I got this large plant last autumn and it now the end of the Winter season (here in Central Europe). One branch seems mainly affected, but it is not the only one. I'm watering it approx. every other week, and it's situated in a living room with normal room temperatures.
Can somebody perhaps please diagnose the situation and indicate how such a plant (rubber fig a bit more than 2 meters in height) should be cared for in general.
