From what I see, the planting mix is coarse enough to allow passage of water. So, 2 questions: 1. Which "grade" of bark chips do you use--from fine to coarse? The bag of bark that I use for my Phalaenopsis does not indicate a size or grade. It says the bark is from fir trees. The pieces are about 1/2 to 3/4 of an inch across and slightly less thick. The bag weighed less than a pound, which should be enough to pot one or two orchids. Do not add any nutrients when potting; wait before adding fertilizer to the weekly watering. 2 Your comment above refers to "plantng medium". Do you mean JUST bark chips, or bark chips on top of orchid planting mix? Some Phalaenopsis growers prefer the fiber from tree ferns. Others use spagnum moss (peat moss that has not been ground almost to a powder). Thus, I used the term "planting medium" to include all three. Whichever you use -- bark, fern fiber, or moss -- use only one of these media. No soil, no compost, no vermiculite, no pea gravel. NOTE: Cymbidium should be planted in a medium approximating real soil. Mine is potted in a mix of fine peat moss and compost with added blood meal and bone meal. Sorry if this was obvious; am trying to do the best by these newcomers. It's okay. -- David E. Ross While many tributes to the late Supreme Court Associate Justice Antonin Scalia now fill the news media, his legacy was not necessarily positive. See my "What Price Order, Mr. Justice Scalia?" at http://www.rossde.com/editorials/edtl_scalia_wrong.html. ============= Confirmed that mine are all Phals. I bought a bag of the bark. Label said from pine tree. Also asked at my nursery; plant guy confirmed use just one medium -- bark. Said ((IIRC) moss-y stuff is used in selling to keep moist. Not necessary for purchaser. Must get other pots. The birthday orchids came in pots w/o holes! Anybody: I found a jar of old orchid bark in junque area. Has been rained on, etc. Is it still good to use? Mix w/new bark? TIA HB |

TIA HB 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. -- David E.

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? -- Dan Espen |

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. -- Dan Espen |

Ross 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?
