The premise I am starting from is that the various methods of backbulb propogation are all variations on the "sphag and bag" approach. But they are important differences. Different species seem to respond better to different conditions.
One very useful variation involves neither sphagnum moss nor a plastic bag. Even so, I consider it to be basically the same process.
A major factor in deciding exactly what variation to use is what conditions the plant likes. If it were in its natural habitat, what would it be facing as it tried to get started again?
Each backbulb has its own story. I will be be looking at each one as an individual and doing my best to help it survive. Orchids are survivors, and given half a chance, will grow and bloom.
