    So did Ron Lin of Sunnybank Orchids in Sydney, along with most of his miscellaneous genera. I use it to space the bark and to aid in drainage. It is light, it is inert (perhaps) and it has worked for me for many years. I do repot my slippers annually so there is probably not enough time for...

    Cattleya loddigesii var harrisoniana 'Jamie's Best' AM/AOS

    From the photos obviously not a lodigessii, this F2 cross confirms it is a hybrid. I wonder what the other original parent was? Still, a very pretty Catt.

    Paphs in ProMix

    Peat and perlite is a popular mix here for some genera. Catts and oncid inter generics. It is usually mixed with a ratio of 6 parts perlite to 1 part peat (Promix looks the reverse). It usually needs the addition of 2 parts crushed polystyrene to stop it "setting" like concrete. A grower...
