Dendrobium parishii finally blooming

[ZSAZSA]

I'm new to the board, but have grown and killed orchids for a number of year; thankfully, grown more than killed.
I have a Den. parishii that has four growths totally covered with gorgeous pink flowers. The plant also has three bare stalks from last year and one stalk from the year before that.
How long should I keep the bare stalks before cutting?

Thanks for any advice

If you mean the canes, do not cut them. Leafless canes are still alive, or should be. They support the plant. I don't know about this particular species, but many Dens can also rebloom on previously bloomed and leafless canes.

Welcome to Orchid Board

I agree with Sonya, the canes can be supplying energy to the rest of the plant so it's best to leave them on.
