THE CULTURE OF INDIGENOUS ORCHIDS
Notes made by Ken Stewart from a seminar he attended.
Reprinted From Horsham District Orchid Club news
Cymbidiums canaliculatum, suave and madidum don’t like town treated water supply.
Our pine bark breaks down too quickly with fermenting bacteria losing air space in the mix blotting out healthy bacteria requirements.
Eucalyptus heartwood ( mud guts) lasts for years. Sap bleeding internally supplies glucose. We can substitute this by5ml pineapple juice to 1ltr of rainwater. Active bacteria loves glucose.
Dendrobium speciosum respond to Epsom salts. Den spec pedunctulatum grows in decaying granite or scoria.
Cymbidium madidium grows in living polypodium fern bark or staghorn.
To be used only in active growth period-Phostogen carbo hydrate fertilisers- half strength foliage sprays followed by Boron and Epsom salts.
Boron 1/3 gram to 1 litre
Epsom Salts 1gram to 1 litre
Pineapple juice 5ml to 1 litre
Vinegar can get PH down.
