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. Late winter around March I take them out and place
in a south and west window until night time temps. Regularly stay
above freezing then slowly acclimate them to full outdoor Sun.

Thanks! I'll get some fungicide for them ASAP

Agreed on the fridge idea. I do the same thing every year / I use the crisper compartment
