So true on the growing conditions, as I mentioned above
@Daisyl probably has the closest growing conditions to Chris's of any of us.
Also true on the scale, mealybugs and other munchers. I recently rescued one of my original Phals that started looking sad for no apparent reason. Lifted up one limp leaf and the back of it was nearly covered with scale! Here I thought I'd' been so diligent on bug detail last winter, too!
They do have those delicious juicy leaves that a lot of the other orchids don't have - I guess they store water and nutrients in the leaves rather than in fat pseudobulbs like the other orchids? Gotta say though, I've had no problems with snails since we installed a strip of copper across the two doorways into our pool cage.
