    I have repotted 6 white phals into one broad plastic pot,
    granules of baked clay for increased drainage then special bark/ charcoal mixture well soaked then settled carefully around the trimmed roots.
    One day later and they all seem very happy. What are the down sides to planting so many in one pot? Will they try and strangle each others roots?

    i dont think the roots really strangle each other, its just far more difficult repotting em again maybe after 1-2 years, but meanwhile i dont see anything wrong with it.

    When in bloom that should be beautiful! Love to see large pots of Phals in bloom--especially white ones---so elegant! Be sure to post pictures when they bloom.

    If one of the plants happened to be diseased, the potential for that disease to spread would be much greater. And watering might be a bit more troublesome depending on your medium and the amount of exposure at the sides of the pot. But I do agree, in bloom, they would be a sight to behold.

    I don't recommend potting many orchids together. It is much easier to maintain individual plants in their individual pots. When they are all in bloom, you could display them in a planter together if that is what you are looking to achieve.

    The main issue will be with water/ root rot. Will the inside middle of the pot dry as fast as the outer edges? Does the medium drain evenly? Also, as Jason mentions the potential of disease spread increases. All things to consider.

    Cheers,

    Dear BD,
    I actually left the centre empty and planted around the edge for this reason. I dont know how it will turn out, it's early days yet but will keep you posted. It might have been better as you say with separate pots to fit into one display on the disease level and root pruning level, but with the large circular mother pot, the smaller ones didnt fit very well for the display. We'll see, they seem to be in growth mode now as spring is just starting here in St Tropez. Wanted to post pictures but dont know what a URL is???
    Best wishes
    Samantha

    Yes.....a good rule of thumb with orchids is: "The larger the pot, the easier they rot!"

    Most orchids do better underpotted than overpotted, and this is because large pots dry unevenly and have bad air flow. This means interior roots stay wet while exterior roots stay dry. If you overwater to compensate, you get rot on the interior. If you underwater, you get dead roots on the exterior. Non-terrestial orchids in the wild have a great deal of air exposure/good air flow to their roots, and potting in bark mixes and smaller porous pots attempt to somewhat replicate that.

    I hope it works out well for you, but taking them out and repotting individually as Bruce recommended might be your best bet. Then when they bloom you can display them in a large planter with some Spanish Moss over the individual pots- it will then look like its one big pot of orchids. Even with your orchids spread on the sides of the pot, I worry that the roots that grow towards the middle will be prone to rot, while the roots on the outside will be much more arid and shrivel up.
