1 This means never, ever use potting soil for houseplants on phals. 2  One of the easiest thing to use is a bark mix for orchids. 3  To re-pot your plant, get a plastic or clay pot (plastic holds water better and you water less with one than clay-if you have tendency to over water, go with clay). You can put a plastic pot with holes into a more decorative container if you want to and then just take it out when you water it. 2  Orchids don't like to have wet feet! 3  Not all roots may fit in the pot and that is normal. ( 4 Phals have aerial roots, you can mist them with a spray bottle when you water the plant).
