Flask: Do I need to get rid of the dead plants?
I recently had to replate some cattleyas from a flask that had become contaminated. Through this process, I've lost probably 90% of the plants, but there are a few (in different flasks) that are still green.
However, each of the flasks has a fair number of dead plants that didn't survive. Do I need to get those out of there? Can they corrupt the environment for the others? I'm hesitant because I don't want the cure to be worse than the problem—opening up the flasks could introduce contaminants that, thankfully, don't appear to be present at the moment.
Thanks for any advice!
