Somewhere along the journey I have been told to be very careful about making sure the cattleya's root systems are to be very advanced before repotting them into a larger size pot.
My question is why?
Has it anything to do with US virus, bacterias & fungus?
Looks like I need to make sure that the differences between growing in the US & AUS are clear and not muddied as the differences are looking like they could be vastly different.
