My tree is loosing it's leaves despite everything I do. I have kept it at room temp but not too warm it's not near a radiator, it's roots are moist but not water logged, I spray I mist of water on it each day and yet each day it's loosing 2 or 3 leaves

Am I doing something wrong or not doing something I should?

Any help would be greatly appreciated

Looks like to roots are suffering. My guess is that there are a lot of dead roots in the pot.. Does the soil smell?

IF this is the case, you have an emergency repot on your hands. If NOT, do NOT mess with the roots.

Thank you Leatherback, I've checked the roots for smell and there is none nor any visible dead ones. It does however feel very cold and damp so I'm leaving well alone now and will keep an eye on it unless you think otherwise
