Hello, my mother gave me one of her orchids (of course it was one that isn’t doing very well). I’m new to orchid keeping and I am having a hard time hydrating this one. The leaves look very dry and have been for awhile. I soak the roots in water for a few hours and they of course swell up but then quickly shrivel up and the leaves never look lush and healthy. Do I just need to soak it more frequently?
