Sunset Valley Orchids Spring Culture Notes
There are two links with lots of "when to water" information. I agree with ES, for now just ignore it - if the current batch of roots have been stunted by watering too soon, it is still in the "rooting" time of year and will probably produce another flush of roots. Follow the instructions on when to water (and more important, when NOT to) If you are tempted to water the plant before its time, put your hands in your pockets so that you can't reach for the watering can (and sing "Happy Birthday" to distract yourself)
