Why Are My Orchid Leaves Dying?
It's a Phalaenopsis. I live in China and this is the first time I've personally ever seen this orchid in dirt. I find it difficult to know when to water it because of this. Most times I've watered it, the dirt has been very dry but the leaves are slowly wilting. Is that a lack of water?
I've found it helpful to soak dry orchids in tepid water for 6-8 hours to enable the plant's rehydration. Most 'phals' will react the way your describe when allowed to dry out too often.
