Dracaena Marginata Leaves yellowing.
Hi, i bought a Dracaena Marginata houseplant in the summer, and put it in my conservatory near a wndow, it thrived there until the weather turned cold.(My conservatory gets very cold in the winter, i do have a heater in there but dont put it on as i dont use the room much.) Anyway a lot of the leaves have turned yellow and some have dropped off.I water it sparingly so i dont think this is the problem as i know they dont like to be overwatered. I moved it into my lounge two days ago as it is much warmer but there is not as much light. Do you think the cold is the problem and have i done the right thing in moving it even though the light is,nt as good.Any help with this problem would be much appreciated. Thanks
