What is going on with the dendro's??

[calypsoB]

Ok so I accidentally left them outside during some bad weather. Ever since then I lost most leaves, have had a scale infestation, mite infestation and mealy bug infestation. It hasn't been a great summer on the bug end of things :S But not I am noticing that there is a brown ring around the canes of the dendros. Is this a major disease? or something that I can just live and let live?


This is also on the nobile types... but slightly more defines as a ring.

Also I purchased some not so happy cat's and laelias but now I am wondering if they have issues too?




So I would love some feed back about what can be done for them or if I should worry. Also I do need to repot the Laelia but I am currently out of supplies :S It was dehydrated prior to purchase too. I have recently pulled it out of pot and found a lot of roots gone, so I have cut them back and tried to get rid of as much black rot as possible. I have also sprayed with cinnamon alcohol. Thanks for the input!
