I use Kellogg organic potting mix with lots of extra perlite. The soil is not compacted, and moist clear through. It is fast draining though. I have repotted it since I got it, thinking that was the problem but it didnt help.
The soil pH tests at about 6.5 and I acidify my water down to aout 6.
The roots could be damaged from before I got it. I have been afraid of overwtaer8ng it, but extra water doesn't perk it up at all.
Maybe I will try tenting it to up the humidity.
