Hey We have always wanted to have orchids at home and fail to make thrm survive. This time we bought them and kept close to the glass window of our balcony. It was all blooming good until we left it without watering for two weeks as we were to travel. Those two weeks were super hot in switzerland. However we had kept some water in a tray with stones to keep up the humidity. By the time we came back we saw all flowers dried and dropped. Keave have these brown patches and dry kind of look. I am attaching pictures of same. What could be the problem. We water once a week by soaking the pot in watet for 5 mins and draining them out.
