Hardcane Dendrobium keiki's

[OrchidSeer]

Hi All,

I have owned and grown a particular dendrobium hardcane orchid for several years which when in flower is absolutely stunning. Each year the plant puts out a single healthy growth and subsequently flowers when in season.

I would like to propagate more of this plant, however due to the single growth each year, and the total absence of keiki's on the plant, I am stuck at this point. (I am also excluding cloning, etc.)

The plant is quite healthy, with three large (90cm+ canes) and three smaller back canes which I removed and potted to see if they will produce a growth.

Does anyone know if feeding a hardcane dendrobium a nitrogen rich fertiliser through the winter/dormant period has the same effect as on a softcane dendrobium, with the production of keiki's at the expense of flowers come spring?

If all else fails I can always try applying keiki paste, but I was curious if the above nitrogen fed method was a viable option as winter is coming...

Thanks.
