For
VFTs, I drain off excess water from the pots, hit them with a sulphur
based fungicide and place in zip lock bags and pop them in the fridge
for 3-4 months. I occasionally check them (once a month) for fungus
and hit with the fungicide if needed. Late winter around
February/March I take them out hit them with sulphur based fungicide
again and place in a south and west window until night time temps.
regularly stay above freezing then slowly acclimate them to full
outdoor Sun. I've been using this method for almost 10 years with no
losses.
