I bought a suavis and a tortilis last year from C&H and they did not like me at all. After some research I came to the same conclusion as mrhappyrotter, moving them to net pots of rockwool mix and growing them alongside my Phrags. I also added an evaporative cooler to my greenhouse which had done wonders here in hot South Carolina. I won't claim success yet, but they have strong new growths coming up and look MUCH better than they did last year.
