Do I need to put my orchid in soil?

I just bought two orchids yesterday from the wholesale market in LA. They put the orchid in a plastic pot with no soil in it. I only see the root and some mixture of rotten wood in the orchid pot but no soil. The roots fit the pot totally. My question is do I put have buy a bigger pot and replace my orchids in the soil pot to keep them live longer. I'm planning to keep these orchids indoor.


PS: sorry if my question might sound a bit confusing. I've no experience in taking care of any plant and I really want to keep these orchid stay alive as long as possible. Thank you

No - Orchids are air plants, they draw their moisture from their very barely moist potting mixture and from the air. Google 'Orchid Care' and you will have more advice than you will know what to do with! Good luck :-)
Reply:Why keep them alive as long as possible?... Everyone can be a good mother for plants and you can enjoy the long life of the orchids with long blooming times and beautiful flowers... First you need to identify the orchid... Since they require different conditions... For example Phalaenopsis orchids (the ones with many butterfly blooms and 5-6 long leaves) need less light than a Cattleya... So identify it first from the link below and search for scpecific care instructions for each one... Good luck...
Reply:yes I would replace the plastic pot for clay pot a size bigger. get some orchid potting mix. like they said previously orchid are some type of air plant so they need a potting mix that will absorb and keep some humidity but a the same time drained very well between watering. If you keep them indoors make sure the watering is done always at the same day. Also I would get some fertilizer for them that can be diluted in water and applied every two weeks.
