I have 3 Phalaenopsis orchids attached on different trees. All 3 currently have flowers and a decent amount of leaves. Recently the roots have started to look shriveled and I am worried the orchids are sick, or dying. 2 of them have double flower stalks and one of them ended up with 35 flowers/buds at one time. Any advice on what is going on or how to save them would be greatly appreciated!
