ok, very first orchid, no clue what I am doing! Ive been on the laptop neglecting my children and husband cause I am all crazy over this orchid lol. On the tag its called a " Burr Nelly Islar 'Swiss Miss'. I looked it up and it looks like the same plant. Anyways. it has 2 open blooms, 1 about to open then a bud. the bud turned yellow and fell off, the one opening was doing good til today when i went to check on it and the opening flower and two opened flowers, the stem turned yellow and fell off i need the run down on what this orchid likes and wants. how do u water it, how much, how often, what to feed it, what kind of light and how much, what temp should it be at and soo on. Oh please I really dont want to kill this thing! I can post a picture of it tomarrow
