What a coincidence! I just checked my sedireas from the same supplier this morning and I noticed a mealy bug on one of the flowers. Immediately sprayed it and hoping for the best.
Oh, when did you buy it from her? I think we may have the same shipment which were affected by mealy bugs. I have been waited the flowers opened for 3 weeks, but just found mealies...what a disappointed. I just repotted them this morning. So tired
