New orchid owner troubles
I received a Phalaenopsis orchid as an anniversary gift about a month and a half ago. I've kept it fed and watered (1-2 times/week) next to a window with mostly indirect sunlight. However, the flowers have almost all fallen off, and a couple of the leaves have turned yellow and fallen off. It was doing really well during the first 3-4 weeks, and now it seems like it's getting worse and worse every day. The only things I can think of: 1) I like to have the window in my room open slightly during the day while I am away, could a small draft cause it to yellow? 2) Last time I watered it, I may have overwatered it (I find it hard to know exactly how much water it requires, but prior to that, I was careful and tried to give it less rather than more if I wasn't sure). What can I do to save it? How much and how often should I be watering and feeding it on a weekly basis? Any help will be greatly appreciated!
