Saturday I went with a few fellow members of our orchid society to the greenhouse of Alfa Orchidées in South France. Among other genera, I bought these two Phragmipediums. I don't know a lot about Phragmipediums, so any help will be appreciated, especially regarding the watering regime. Do these two need to have 'wet feet', or should they just don't dry out between watering? Thank you for your input.
