Zygocactus advice requested

[Ronald Cliborn]

I cannot get enough zygocactus - Christmas or Thanksgiving.
I would say that mine do fairly well, but they never look like the
ones in the stores do. Even when I wash the plant, the still don't
look as succulent as they do in the store. I know that the stores
have a spay wax they apply, but that is not it. They seem to have a
healthy glow in the store that mine at home lack.
I repot mine twice a year using miracle grow potting soil. Should I
use plain peat moss instead?
Mine flower like crazy so that in not a problem. I would just like to
make them grow the best that I can.

Any advice on this subject would be greatly appreciated.
I'm sorry if my message sounds gay, but I really like the
zygocactuses.

Thanks
Ronin
