I bought Dendrobium Stardust 'Choyomi' in bloom in March 2010 and never managed to get it to rebloom. It grew keikis like mad but didn't bloom.
It started to deteriorate a lot in Sep 2012 and the following May I finally realised that it was absolutely covered in spider mites
In September last year I finally decided it was beyond saving HOWEVER I had already taken two keikis off before it got the mites, and I saved a further 17 keikis when I threw it away but those keikis were barely more than tiny patches of green on otherwise dead looking canes.
Miracale of Miracles, I seemed to finally beat the mites and those 17 keikis grew like mad in the last bit of last year. So I now have 19 of these, 10 of which are a decent size (for a keiki).
A couple of people here in Europe had their name on some keikis however in just the last few weeks I've spotted mites again
and I'm not going to share mites with anyone, they will have to be clear a good year before I send them out because they had seemed to be gone for 3 months, then came back.
ANYWAY, the two original keikis I took flowered this year... and I know what I did differently... no fertiliser since the end of August! Otherwise treated just the same, watered regularly all winter and kept in the house. These are a primary hybrid of unicum but don't seem to want to be deciduous (parent didn't do at all well when I tried a dry winter).
Here after my rambling are the flowers
