I think you are right, jimscott.
In the wild, temperate and mexican pinguicula are used to getting moved around by wind, rain .etc.
So they are not sensitive to root disturbance.
They dont develop much root because they grow on cliffs or rocks with little soil, the plants that grow on cliffs or rocks with little soil are called alpines. So they dont have much room for root development. Some Pinguicula, like P.grandiflora(temperate species) is getting used to moving around so much, that if you dont repot during dormacy, they dont grow as well!
However, D scorpiodes has plenty of room to grow and develop lots of roots, it has much more room for root development then Pinguicula do. Its not used to moving about, so it is sensitive when you disturb its roots.
Does anybody else agree with me and jimscott?
My P.laueana is recovering, its lifting up its flower stalks,
they used to be right on the soil before.
