For sure, there are huge differences with different types of Dendrobiums. But that's to be expected - it is a huge genus, Habitats go from humid tropical rainforests to the foothills of the Himalayas and everthing in between so different species have very different needs within the genus. There are different sections within the genus that helps. (To get info about those groupings, do take a look at IOSPE You'll also get a summery of habitat information.
Here is the blurb on Den smilliae

It suggests a "slight" winter rest. I'd hold back on fertilizer, but not water... you water everything less in winter because things don't dry out as fast. (Unless, of course, your growing conditions are hot and super humid like they are in Papua New Guinea lowlands... which they probably aren't) |
That's an awesome website I have been on there but I need to take the time to really sit down and dig in especially on the lovely dendrobiums. I had no idea on the peroxide. I've had so many people tell me to use it especially when I get a new orchid to help kill any unknown infections. I will definitely keep that in mind and start experimenting with the physan more. Hopefully I just won't need it but in all things growing there's always something to battle 😉

perhaps the fungus had dried up now, in which case- great! keep it going!! if not, a couple drops of soap into a small spray bottle and give those canes a good spray down with a thorough flush of the media afterward.
ok, sorry ob, i will stop again with the soap nonsense

Lol I love the soap mixtures! I used them for pesky mealybugs and works great. Do you have a preference? Would love to hear your favorite. I just starting using a tea tree and mint soap very diluted so it doesn't burn leaves. Has made a night and day difference. Worked better than the rubbing alcohol. Hadn't thought to use it for fungus. Will definitely give it a whirl. I'd much prefer no chemicals if possible. Yes it is all dried up!
