It had just been moved into a new position not far from before (same soil) but it was receiving more light. Not once has it been allowed to dry out.
I have a Tree fern which I believe is Dicksonia antarctica.
I have had issues with this since September when i noticed canker, and a possible edema. I had treated the wound accordingly back then with Bordeaux mix (Copper) and also dug more sand and compost into the soil around the base of the trunk understanding the problem to be one of respiration. I also used a mix of armatillox and water to disinfect the soil.
Since then, the tree has been covered over winter, and what was once an orange wound has now become a white scar ?!? Is this a sign that it is healing and that I should cut the infected part away now and re-disinfect, or does this look really bad and if all else fails cut the tree in half and stand a chance of saving it ???

I would be truly grateful for any advice that will help me save the tree, or at least half of it,
