Dend. friedericksianum

[pheli]

Like other nobile dendrobiums, Dend. friedericksianum has a winter rest.
My plants usually stop growing in late autumn and have their new growths in early summer.
I don't know if this species will have a winter rest in tropical areas like your country. But a friend in south Taiwan grows this species, too. He said that his plant didn't stop growing in winter but grew slowly.
Anyway, you can follow the rules for the nobile dendrobiums. That will be helpful.
