Yes, it looks like a dendrobium. The small cane is supposed to lose its leaves eventually. They are the oldest canes. That is OK. And the current cane looks vibrant with the plants first bloom. I really need a close up of the potting material but it is usually a good idea to quickly repot the commodity type orchids. Air is needed in the mix. They are air plants. It appears to be lacking sunlight. The leaves are their own litmus test. A beautiful emerald dark green is not enough light. A yellow pale green is too much. Watering depends on the environment and the combination of potting material and type of pot (plastic or clay) or mounted. I like the set up that allows the most water. Clay pots and lava rock medium. With warm temps and good evaporation I can water every day. The human needs, life style and schedule need to be considered in creating the right combination of medium and pots...Regardless every 2 weeks is punishment to that orchid. Once a week with a plastic pot and a mix that holds water is a minimum.

The next step if you want to join us orcaholics is to join a local orchid society. Each local climate has its own tricks that the locals know. They will provide the best advice. Google The American Orchid Society to find a local society near you. The best way to learn.

Thank you.

I bit the bullet and repotted because it's been way too long in that media. It was basically stuck in sphag and peat soil. Most of the roots are totally rotted out, so I saved what I could and repotted with medium bark, charcoal, perlite and clay pellets (like hydro-ponic stuff). I had been watering every other week assuming that the media was too water rententive, which it was, but even more so than I thought :(

Should I let it dry out fully between watering?

I will take another photo tomorrow with better light for the leaves. I think it's enough light, but I can easily give it more. It's currently in a south-facing sunroom that is 60F at night and 70-90F during the day with 40-70% humidity.

The current blooming cane definitely has something beginning to grow from the center where the current spike is. What is that?

I'd love to be a AOS member, but my current life doesn't allow for it :( Meetings are an hour drive away at 7pm and I have 2 little kids who need me to help them get to bed at that time. In 10 years when they want nothing to do with me, I'll happily be an active member! Until then, I'll have to seek the expert advice from the internet.

I agree, joining a local orchid society is the best thing you could do. They usually only meet once a month. There has to be one in your area.
The plant looks healthy to me, but I agree with 'Shavedmonkey' it could use more light. The leaves look dark green. Dends like to be almost dry before watering. I don't know what is appearing in the flowering growth, maybe a picture would help.

Good luck, these are strong plants and with the right light and watering, you should get new spikes starting in September and blooms around Christmas.
