Yes, I would think you need to repot. The two keiki's are as large as the parent. I would pot each plant separately. Use a new single edge razor blade to detach the keiki, being careful not to cut the roots (or your fingers). If you have superthrive & KLN add these (per directions on pkg) to your water & soak the roots in this solution for awhile. Then pot them up in your chosen medium. I'm sure they will do great - phals love new medium and are not fussy about when you repot like some orchids. Good luck.

I'd leave it alone if it has spikes. Trim the dead roots after flowering and when new roots are forming. Keep it in very bright light! Congrats, Bob

Hi again Pat, There's no need to apologize for questions. It's what keeps the experts here on the forum-questions from a beginner ;) Good questions! Because orchids are epiphytes, that means they require a lot of air around the roots. Clay pots are porous, which provides the roots with ventilation. Plastic pots are not porous, however. That's why most people who use plastic pots create ventilation holes on the sides to provide extra ventilation. I don't believe roots actually have that much of a "preference" when it comes to what they attatch to. They will latch on to clay a lot harder than plastic, which means once an orchid that is potted in a clay pot needs repotting, the poor grower will likely have a hard time attempting to detatch the roots clinging to the clay. I don't think however that that means roots "prefer" clay to plastic. For your second question-yes, in the wild epiphyte orchids' roots do have room to spread. However, they also need to latch on to something in order to secure and anchor the orchid in its position, otherwise the plant will fall and will likely die. A small pot allows roots to attatch to the sides faster, giving the orchid a sense of security. If you attempt to pot a tiny orchid in a huge pot, the plant will have a hard time trying to find something to attatch to and will likely not do as well as a similarly sized plant in a smaller pot. Bigger pots also retain more moisture, and if the plant is too small the extra moisture sitting there unused could promote some fungal growth. Hopefully I didn't mess anything up in my explainations :p Again-good questions!

Thanks for the information on soils. I am a cut flower grower so I can grow many difficult seedlings outside but my "houseplant thumb" is sorely lacking in experience. My methodology up to this point was grow it till it dies and then discard :) That was when I had a busy life, now with retirement I find I have the time to pay attention to and enjoy houseplants. Hence my new found delight in orchids. As to the coir, I use it for starting seeds and love it. I was afraid that it was too small and would wash out between the bark in my orchid mix.
