I have a orchid plant that had flowers on it, but I had to go out of town for a week. When I got back the flowers fell off.
Will I get more, and when?

You may be able to ID your orchid at the orchid society website. Here are tips for getting an orchid to bloom: https://www.gardeningknowhow.com/ornamental/flowers/orchids/make-orchid-bloom.htm
