Hi Shane,

Thanks so much for all of your advice, I really really appreciate it.

In the end I unpotted the plants with mold and cut off dead roots that were present and the repotted into fresh bark. I think that I didn’t get all the dead roots in the first repot and that this was the main cause of the problem to be honest. I think that I have managed to address the issue but I won’t speak too soon!

Kind regards,
Caroline
