No one will be able to give you help unless you tell them where you are in world and where you are growing the orchids and the type of orchid(s).

Sometimes, you just have to wait a while for the flowers to come! I am not experienced in this part of orchid growing, so I actually don't know much about this..

I am pretty sure that there are some ways you can influence it to grow, such as changing the light/heat levels, but I don't know the specifics to that..
