Do you cut the stem off an orchid after it blooms?

No, you don’t need to cut the stem off an orchid after it blooms. In fact, it’s better if you don’t, as this will help the plant conserve energy by reusing the spike for future blooms. You can remove the flowers once they’ve died off and faded away. If you would like, you can trim the stem to make the orchid focus its energy on its roots and leaves instead.
