Hello! I am appallingly bad with plants, (and have no knowledge whatsoever) but very much loved the idea of a little orange tree. At first it seemed to be doing well enough, but then very rapidly started dropping leaves. The rate of destruction was so rapid I'd given up on it, but it seems to have stabilised with half of its leaves gone, and with the remaining half actually doing sort of well, with the oranges having now developed from green to yellow/orange. It's like half the tree gave up and completely died, with leaves gone and branches brown, while the other half flourishes with green branches, healthy leaves, and developing oranges. Does anyone know what might be happening here? And perhaps more importantly, can I ever get the dead half of the poor little thing to recover? At one point I noticed white stringy bits popping up from the soil. I yanked at them and they snapped. I then realised they were some of the roots. (I told you I was appallingly bad with plants!) But I wouldn't think accidently snapping a few small strands of root would kill the plant. I watered once a week during the end of summer, watered maybe every couple of weeks through winter. Every fourth water I added in a bit of citrus feed. It is by a window facing the sun and so with a fair amount of light. but with the houses opposite us casting shadow the sunlight is rarely direct. I've attached some pictures.
