I have purchased a nice strong kaffir lime tree in the summer, it was growing quite well, flowered and wanted to bear fruit. When autumn came, I moved it inside in a insulated shed where the room temperatue is between 15 and 19 °C. However it lost an alarming amount of leafs so despite the fact I knew it's because of the adaptions, I was afraid the place was too cold so I moved it in my living room near the biggest window for best light conditions. There temperatures are a few degrees higher, the back door is not far so sometimes a cold breeze can come through when you open it, but the plant kept losing leafs on a steady pace. In the beginning of January it lost its last one, and the branches began to color brown. I also have a normal lime tree next to it with the same conditions. A few weeks ago the first proper sunlight came up again after weeks of cloudy and rainy weather and I noticed odd bumps on the trunk and stems of both trees, turned out those were scale insects, which I removed on both trees. How they got there I do not know since I sprayed both plants thoroughly with water before putting them inside. Even after removing them, the browning branches became more brown and neither plants are drinking much because they're in winter mode, despite all directions not to prune I had no choice, the brown was reaching the main trunk so I had no choice but to cut off all dead parts. Both trees are now down to 2 branches each which are healthy but I fear they won't survive till spring. In an effort to try again I am germinating kaffir lime seeds so I can try again and do better next time, but first I need to know exactly what i am doing wrong. Much googling resulted in conflicting information, so I am not happy of the misinformation floating around. Some say to keep lime trees warm and moist, others to keep it a bit colder and dry (during winter I mean) The lime trees I kept warm and moist (not wet, I watered once every week and just a bit, the lop layer of the soil was very dry and I use a moisture meter , however the deeper levels of the soil was moist enough ) I also have a smaller kaffir lime (I think its a dwarf varient ) which I kept in that colder shed, and watered only once a month, and that one too lost the older leafs but still has his newer ones and has no brown branches at all. So i am wondering, which of all the information is the correct one, how can I safely hibernate those kaffir lime trees without losing all its leafs Do I have to keep spraying water over the foilage during the entire winter period or not?
