Q.Orchids
What does it mean when the stems of the flowers go brown and no flowers bloom?
Is your Orchid done blooming?
You can cut or prune away the spend flowers and stem.
After blooming an orchid needs a dormancy or rest period before blooming again.
I have listed several links with care information on orchids for you.
