Oh Emma that is very kind of you to say! I approach root problems in aroids the same way as in repotting orchids....slow and methodical.
I know what you mean about the sellers looking to make a quick buck...we have a lot of those here too. A few of us call them 'node flippers' because they import plants from Asia and resell them almost immediately for 3-4x what they paid for them. They aren;t real growers, they are just opportunists
