Q.Is there a special compost when repotting an Orchids ?
I have never repotted orchids before I want to do it the right way. Thanking you M Pugh.
Yes, orchids need special, very fast-draining potting mix. It is sold as Orchid mix and is widely available in the US at garden centers and home improvement centers. Hardware stores may also stock it if they have a decent-sized garden section. Orchid mix has lots of bark in it so water drains. Regular potting mix is too rich, too wet for orchids. Here is an article describing the repotting procedure: https://www.gardeningknowhow.com/ornamental/flowers/orchids/repotting-orchid-plants.htm
