Fill your new orchid pot with the potting mix, then dump it into a container about twice its size. To prepare orchid potting mix, you'll need to soak it in water overnight. This will help it retain enough moisture to sustain the orchid. Go ahead and fill the bucket or bowl to the top with hot water. Don't use cold water, since the potting materials won't absorb this as well. Be sure the soil is at room temperature before repotting the orchid. You can use a strainer that you'd normally use for food (you'll want to clean it well afterward) or a large piece of cheesecloth. Drain out all the water so that all you're left with is wet potting mix. Run more warm water over the mix to rinse out any dust. Carefully lift the orchid from its old pot, loosening each root individually. If the roots are stuck to the pot, use sterilized scissors or knife to help free them. It's important to use very clean equipment, because orchids are prone to getting diseases. You can sterilize your trimming tools by wiping them with rubbing alcohol on a rag. Use your fingers and a clean pair of scissors to carefully clean up the roots. Pick out the old mix - charcoal, wood chips, moss, and so on - and discard it. Use the scissors to clip away rotten or dead roots, taking care not to damage any healthy plant matter.   Roots that are soft and limp are probably dead, so go ahead and remove them. Untangle the roots carefully by easing them apart with your fingers. If you're using a pot that you've used before for orchids, clean and sterilize it with boiling water to get rid of toxins and kill potential disease vectors. If the pot is large and deep, line it with broken pieces of terracotta or packing peanuts to help with drainage. If you're using a shallow pot, this step isn't necessary.
