Hello! I'm Chrysa from YouTube comments about my Ficus ginseng. After we were gifted it it lost its leaves. I'm a newbie and learned yesterday what kind of plant it is even though we have it for months. 
I never used fertiliser. 
I water it once the top gets a bit dry. 
I cleared out the grey's pot water yesterday, don't know how long it had water at the bottom ugh. 
I don't know if it gets enough sun (plus it's winter now.) 
I ordered a grow lamp and a 15 10 10 fertiliser. They haven't arrived yet. 
What would you suggest I do? I'm afraid to repot it rn in this vulnerable state. 
If I pull it out it gets out all together, meaning it's not stuck to the pot which I always found weird and you can see in the pictures.
I'd really appreciate your help and guidance. 

First of all ficus ginseng is not a bonsai. You can get good care advice for it in any potted plant community. 

Ficus likes warm, humid and sunny conditions. In north hemisphere temperate climates they always struggle in winter.

One way to adress the problem is of cource more sun and humidity. The other sounds strange given the previous information. But keeping the tree in lower temperature will slow down metabolism and make it cope with the lack of sun better. Most people have very good success with that.

In summer always keep your ficus outdoors. It makes it stronger and better prepared for next winter. 

Shouldn't I keep it away from direct sunlight?
What sounds strange?
Summer in Greece can reach 40°C. I thought it was an indoor plant? 
Now I put it in a sunnier place, I'll see if it'll help

In summer I would keep it away from direct sun in greece. In winter not.

What is an indoor plant really?? there are not one single plant in the whole world that live naturally indoors. It is a lable for plants that need protection from the coldest part of the year. Indoor does not meen livingroom conditions. 

In some parts of greece I am sure ficus can be outdoors all year most years. Just take it indoors during periods of 5 degrees or less. 

Makes sense! Alright, thank you I will do that!
