Mixes for Dendrobiums.
Navyderek suggests using stones & varying the mixes for dendrobiums to aid watering
(?standardization). I would like if I may ask a supplemental question? based on "the earlier classification of 5 main ecological groups using Wood & Baker & Baker.(Mesial ie cattleya conditions, Warm Tropical, Xerophtic ie warm, dry habitat & Very wet summers, Monsoon & Temperate Rain Forest)". I think I can work out mixes for Xerophtic [high proportion of perlite + stones (eg kingianum) or spaghnum for monsoon (eg callista) and temperate rain forest (eg oxyglossum such as D.cutherbertsonii) but I would be grateful for rough guidelines for the other two ecological groups? Would it be roughly half-way in between high & zero or something else?
I think I am still aware of the need to look out for decidious dendrobium habit, temperature & light levels for all of these or am I making it all to complex? I want to do the best for my collection of 2 to 4 year old collection.
Thanks again for all your help
Minda , I know this is a late post but what Dendrobiums do you have ? if they are cool types ie nobile then they are fine to 10c , i have some Aussi types kingianum ,delicatum that have been down to 5 c i also left a nobile in there and it is doing very well .
keep them on the dry side ,DON'T mist until warmer weather .I grow in a greenhouse so it naturally has high humidity in winter i wish i could get it lower in winter .
