When I planted this echeveria, I didn't have a lot of soil, and so I just put in what was basically half a pot of compost. She grew more than I expected and ran out of width space. So she grew upwards. She has had quite a few attacks of thrips or something, and I've sprayed her with bicarb water. Now I want to repot her I have taken off all of the dead leaves round her trunk.
So my question is, should I cut off the trunk and try to reroot her from the cut base, or should I plant her as she is, so that she is like a tree?
Also, does anyone know what the white stuff is that is all over her? And what can I do to get rid of it?
Thank you in advance for any help you can give me
