I have a sharry baby that I just cant seem to make happy. When I got it the roots were infested with what looked like ants. I am not so sure they were ants tho. I treated it and got rid of the insects but it almost killed the plant. I have had it in bark/char/lava rock since and nothing. Yesterday it got knocked over and fell out of medium. The roots are not growing. So I put it bare root into a plastic container with a little damp sphag in the shade. What medium should I use now? I am at the end of knowing what to do to save this little thing.
