Hardening of orchid plant

[uday]

I have just joined this wonderful forum! Can any one tell me how to harden the orchid plants so
as to get multiple blooms from orchid. I have year old dendrobium. I have repotted the keiki of dendrobium and it's showing flowering spike. I have just purchased purple phalaenopsis also. But after visiting a orchid grower co. I found that, the orchids placed there were very strong and have multiple blooms.

Okay. First off, I think you're misusing the phrase "hardening off".

Hardening off refers to taking seedlings out of a flask and prepping the plants for an environment outside of the flask. This process forces the plants to adapt by producing more leaves that are harder in texture than the leaves that were formed in-vitro. The reasoning for this is that the humidity inside a flask is most likely close to 100%, but the humidity outside the flask is much lower.

Secondly, I think you want your Dendrobium keikis to bloom. Am I correct?

If so, then all I have to say is, you're not giving the plant enough time to mature in order to bloom.

Hi Uday your question was not very clear. Any orchid including your 1 year dendrobium should take a while to flower. My experience has ben that Den take upto between 2 and 3 years - from the seedling stage to flower. You cant rush it to flower. Why dont you post a few pictures it will help us to guide you or even answer your questions.
