do you grow these species ?
Yes. I have around 300 pots of them.
I have tried to respond to your PM but it doesn't appear to be working for me.
I currently grow a large range of species from the following genera-
Pterostylis, Diplodium, Linguella, Taurantha, Bunochilus, Plumatochilus, Oligochaetochilus, Drakaea, Spiculaea, Elythranthera, Diuris, Thelymitra, Microtis, Corybas, Cryptostylis, Chiloglottis, Simpiglottis, Caladenia, Stegostyla, Arachnorchis, Acianthus, Cyrtostylis, Leptoceras, Pyrorchis and probably a few other that I cannot recall at the moment.
Many are now beginning to grow and the first few are now in flower.
Obviously my seasons are opposite to yours so you'll need to adjust.
My plants are grown in a complex mix of co**** sand, finer sand, 8mm pine bark, loam, composted leaf mould (containg Eucalyptus, Casuarina and silky oak), blood and bone as well as various trace elements.
Watering commences in late November for the Diplodium sp., in late January for most other species and late March for the Caladenia species.
During the warmer periods the pots are watered about every second day. During the colder winter period, probably about every 1 week.
They are all easy to grow species. The Chiloglottis can be kept damp even during dormancy.
These are all species that I'd begin to water in late January down here.
