Orchid repotting is not complex but it is unlike that of other flowers. First of all, no soil is necessary, but a potting medium is required.
Choose orchids pots which are deep or shallow, depending on the orchids repotting need. They may be clear plastic pots or a heavier ceramic pots. Or possibly your orchid would be nourished on a piece of bark or block of word or in a basket.
The day before you repot, pour your potting medium into a bucket that is two times the volume of the potting medium and cover it with hot water. The following day pour the wet potting medium through a sieve and rinse with cold water. For todos that come next, click the link.
