Hi - i have never gardened or had a plant in my life. i wanted an orchid so my sweet boyfriend (who also does not garden) bought me a beautiful one - it was fine for a while - i heard they need minimal water and light, so ive had it in my bedroom with about 3 tblsp water 1-2 times a week and indirect sunlight. 2 flowers fell off about 10 days ago, then if was fne again, but now a leaf died and 2 more flowers are going, and there is a little brown on the petals - i have no idea what species it is or where he got it. does anyoe know and can you help me not kill this beautiful thing?? Thanks!!
