I've obtained a number of Orchids over the years from the supermarket most of them are Phalaenopsis or Odontoglossums. They've all finished flowering, and the flower spike is still jutting up but looking real dry and dead. I wanted to know if it would be a good idea to just hack off the dead flower spike, or should I leave it on?
My second question is I've brought back a overwaterd Phalaenopsis that had a lot of rotting roots all over the place. It's doing much better now and has since shot out new roots from the rhizome. I wanted to know if it would be okay to hack away the rotted roots as some of them are green in parts and rotted in other parts on the same root?
