Pollinating Dendrobiums
 

I have pollinated cattleyas, laelias, and intergeneric cattleya tribe
plants. I've successfully pollinated paphs, vandas, epidendrums,
ascocentrums, sarchochilus, dendrochilums, and angraecums. But I can't
pollinate a dendrobium...not one. Not chrysotoxum, densiflorum, aggregatum,
or lancefolium. Not aphyllum, secundum, bensoniae, kingianum, alexanderi, or
spectabile. I can't even pollinate some of the large hybrids.
I know Mick would say that the world is a lot better off because of that.
But it really bugs me that I can't get a cap to stay on a dendrob. What's
the secret? What am I missing?
