As I am planning out my gs/cork background I would like to incorporate some pre-thought out places for broms. I’ve read you can place the stolon directly into the gs. Would I need to poke a little drain hole through that part of the gs so the stolon doesn’t sit in water and rot? I’m also wondering how the stolon would get much air movement being stuffed in there. Same question for a cork round. I’m not sure if I’ll fill my rounds with sphagnum or gs yet, but should I drill drain holes into those as well if I want to stick broms in them? Thanks!
