Whenever I get around to it as bugs can hide there and they can build up in numbers and go unnoticed for a fair while and then suddenly they turn up everywhere. Cheers
You have a wonderful collection! Thanks for the tip on using the large Orchid bark, I will pick some up closer to the repotting. I have a bag but it may be a bit old now.
I also have a cymbidium that needs to be repotted. It hasn’t flowered in years and has a lot of black spotting. Should I bother to repot or is it a lost cause? I just bought a few Cymbidiums from an Orchid nursery in regional VIC and I’m a bit worried that it may cross contaminate them. Any advice would be really appreciated.
@@mopsbouquet...spotting on leaves of Cymbidiums is fairly normal, as long as it's not rampant. Potassium bicarbonate in water is a safe fungicide if you're worried. Repot in coarse free draining mix and a fairly tight fitting pot. Remove any soft back bulbs and trim away dead leaves. Keep an eye out for scale lurking in hiding places. Good luck !
Rest ? Not really as these are always active in one way or another with anything from new root development, new growth, development of flower spikes and finally flowering... and then it starts all over again. The largest of my Den. delicatum (alongside of my largest Den kingianum) lives outside and gets rained on a regular basis throughout the winter.(but no frost)
...btw... my 'soft cane' Dendrobiums do get a bit of a rest as they drop some leaves and I ease off on the watering. Most of these are different cultivars of Den. nobile. They're still active as they're developing flower buds and one is in flower... 'Red Ballerina' and another will probably flower next week. Tasmanian Autumn... it was down to 6°C last night with more cold nights on the way. Cheers
Do you remove the old sheaths as a routine thing or only on repotting?

Thank you.
... rotting potting mix may not be the best option. It's always good for something else.

Thanks! Will give that a go.
Do you water or rest Dendrobium in winter & When are their roots most active?
