If the flowers were on a long spike, but it off when finished. It won't flower again.

sorry, meant 'cut.' I guess that's why they have a preview button.

So cut off the long spike where the flowers use to be? To where? As you can see I am clueless... I do have new canes and those will hopefully flower, right?

I like to cut the spike fairly short but leave enough so that I can see that the flowering occurred since one mark of good culture is that every new growth flowers.

Dendrobiums need quite a bit of light to grow well. To get it to flower again, you will need to have a growing area which will likely not be the same as the area where you had them to display.

Thank you! I will move them to a sunnier window and continue to water and fertilize...any other tips?

What type of Den do you have? Some (nobile types) flower along the length of the cane with flowers comming off all along it. Do NOT cut this type back.

Others bloom in a similar way to a phal with a spike comming out of the top of the cane. This spike carries all of the flowers well clear of the cane itself. This spike can be cut back within an inch or so of the cane when it has finished blooming.

If your plant has spikes similar to these, cut them down near the leaves of the cane.

DONT cut the stem. Many will reflower, even if they have no leaves and by cutting into the living tisue you always risk introducing disease.. The only canes I remove on mine are those that are shriveled and dead. If your plant shows no sign of new stems growing from the base, keep it dry for a while then water when it starts to regrow, which should be soon.

I thought I was clear, cut the spikes (flowering stems) not the canes! My photo is showing the flowering spikes, cut them off when finished.
