Turns out the other half took some pics while I was washing my hands - this was what I was left with after removing the worst roots and the moss etc.
For some reason they look green on this pic, but they were much paler. They actually look better here than I remember from earlier - although there aren't many there... I'm hoping new ones will grow.
How can you tell when there is new growth? And when does this usually occur? How long does it take? Sorry for all the questions, but I am so new to this...
It doesn't feel as steady in it's pot as it did - is that because of the lack of roots? Or should I have potted it a little deeper? No roots are showing over the surface.
Fingers crossed...
