Hi - I am new to these forums, and to growing orchids. I received an orchid about a year ago and have managed to keep it alive and healthy (I think!) As you can see in the attached pics, there are two old "stems" that at one time carried blooms. Once the blooms died and fell off, I was left with those stems. Is it ok to cut them off? I have a new stem that looks like it is carrying some buds. Any info is appreciated - thanks!
