Hello everyone!
I'm back with more questions on my "only child". It's been staying outside for a couple of months now since the night time temp rarely dip below 50. Since I got it in December of last year, it only have a total of ONE leaf unfurl, and when that leaf fell off about a month ago or so, it seemed to have gone downhill from there. I got this as a rooted cuttings back then, but I never checked if it's true or not since it was sent in its pot, I assumed it has roots, and didn't want to disturb it.
I couldn't stand that it's not doing anything else, when there are new leaf tips, they seem to turn black and fall, so I unpotted it today, and this is what I found (see pic). No sign of roots whatsoever. If it did have roots before don't you think I'd find some roots remains in the soil? There was none, which I think is so odd. Up until 2 months ago, I used bottom heat inside the house, so it might had some roots since a leaf was able to unfurl, but maybe I took it out too early and the roots decomposed, that's why I didn't see any sign of it all all today? Now that the weather has gone up considerably during the day, I'm hoping that this can be rooted.
The bottom part looks black in the picture, but I didn't wash it thoroughly, so there are soil left there. It feels firm in that area though, not mushy at all. Some part of the stem feels a bit soft, but more like underwatered type soft/wrinkling instead of rot, but then again I'm new at this, so not sure.
I repotted it into a black plastic pot, and set it under full sun with plastic bag covering for extra humidity.
If it helps, this is suppose to be "Kona Rainbow" although I can't find any info/picture on it anywhere.

Any advice and suggestions will be greatly appreciated. Thank you.
