Hi everyone!
I have a chinotto (citrus myrtifolia) that i bought in the spring. It was doing really good until i moved it inside, because temperatures are now too cold here.
Now it has a problem: it lost many many leaves, and it keeps loosing them. I put it near the suniest window i have(south), away from any heat source. I water it only when the soil feels dry to the touch. I also fertilise it, and i mist it often so it won't be to dry. The leaves it has now on are curled an about to fall, they seem really dry and they have a yellowish-green color.
I really need your help, it was expensive and this citrus is really important to me. What to do with it? It also has 10 small chinottos on it, it would be pittty if it would die. Please help me.
If it won't get better, i will move it in my keller, in a dark place, so i think it will hibernate until spring. I don't want to lose it. Thanks!

You can grow it indoors and water it normally. Give it as much sun as you can. But there probably nothing really wrong. Leaf loss and curling is normal. It needs to adapt from outdoors to indoors.
Don't fertilize! Grow is slowing due to indoors and slower growth. Trying to speed up growth by fertilizing is not a good idea.
Misting doesn't really accomplish anything. A room humidifier would make a difference. The effects of misting, if any, last for a few minutes.
