Why can't tropical Orchid Mycorhyzae survive in temperate greenhouses?

    Very often, I've seen ideal conditions for root-fungus symbionts in the pots of 
greenhouse orchids.  Plant debris regularly accumulates everywhere in conservatories 
-- even on top of orchid roots. So why could't we bring some samples of the various 
epiphytic Mycorhyzae from the tropics and infuse potted orchids with them?  It would 
eliminate the need for a vast assortment of artificial fertilizers and perhaps make 
for a far more natural and productive growing environment -- wouldn't it?
