Orchid Planted in a Plastic Liner
My orchid is in a plastic sleeve and then in a clay pot, should I remove it from the plastic?
Botanical Journeys Plant Guides
If you can slip the orchid out of the plastic pot without damaging the roots then go ahead and remove it from the plastic liner and set it directly into the clay pot.
If the roots do not come away from the plastic easily, leave it just the way it is.
The plastic pot will hold more moisture than the clay would so just be careful not to over water the plant. Repotting Orchids
