I generally do mix some old bark from the flower pot with mostly new bark when repotting. However, do not depend entirely on my advice. I recently repotted both my Phalaenopsis, and then one of them died.
I have one orchid for at least 3 years. Never re-potted and it looks happy to me. There are plenty of roots outside the pot but I don't see a problem with that. It gives me an opportunity to mist the roots every few days with water.
So, why do I need to re-pot this plant?
If ALL of the NEW roots are outside of the pot, the plant is not getting any nutrients.
So, the roots need to be inside the pot to work.
I'm going to need a much bigger pot and this plant is already too big.
Time to visit youtube again for replanting orchid videos.
On the 3 Phals from TJ, the roots of one are climbing out top of pot Since these pots don't have drainage holes where roots would normally protrude, I assume this should be sign that plant (s) needs repotting?
