JB,
I also can't grow orchids. They say if you can grow AVs, you can grow Phal orchids. I
must be a special case.
Have you ever tried Phal orchids?
The only experience I've had with Gardenias was the ones my Mom tried growing. They slowly died one by one, but I couldn't say if she was doing the right "things" with them or not. I think they do better in the ground here. But, it sounds like the ones I'm used to seeing aren't as special and tender as the ones you grew.
Unfortunately mandevillea freeze here, but they sure are pretty! I saw one growing up someone's mailbox one year and hoped to get one myself.. That was until Mom told me they don't survive our winters lol. I take it you grow yours in pots? I wonder what makes certain plants more mealybug susceptible than others?
