If you have multiple stalks on a rock just peel one off or cut it off. get as close tothe rock surface as you can adn glue it onto a plug or another rock. At least thats what I had to do. In the pico one of the stalks split and was starting to adhere to another rock so I peeled it very carefully off the other rock and it seems to be fine.
