I have a Phala and would like to know what orchid mix Is best for mine. also I have sphagnem ? moss on top of my pot. underneath there Is green shoots, maybe roots that are growing on top. would this mean to repot? not sure how long It's been In this same pot. thanxs

You have a ton of choices on what to pot your phal in. There are probably at least 20-30 choices of single items and various mixes. In the wild phals grow on trees - hence, no mix at all. Someone in my orchid society has all of his phals mounted on bark - none of them planted in any media at all. These are in a greenhouse with plenty of humidity. They are thriving. Putting them in pots and media is for OUR benefit - to be able to care for them less and gives us the opportunity to move them as we wish. In general, if you tend to over-pamper your plants I would suggest larger media - like medium to coarse bark - that drains very well (soak for 24-48 hours before use). The quickest way to kill a phal is to keep the roots too wet. Professional growers and longer term growers often use a finer mix and then monitor the moisture levels within to assure that root rot issues do not develop - some use straight NZ sphagnum moss, a mix of sphag and bark, coconut chips, etc. I am currently having good luck with a mix of coir (coconut fiber), perlite and small amount of charcoal. Lots of DIFFERENT options work well for different people. It is up to each person to find a media that works well for your environment and your care techniques. Good luck - Mike

Medium bark is probably a good choice for a beginner.
