    Default Phalaenopsis New leaves falling

    Hi, I bought a phalaenopsis orchid seedling 6 months ago. It was grown through tissue culture in a sterilized medium. When I bought it, it had 4-5 Leaves and had grown to 4 inches height and had overgrown its sterilize container.
    I put it in a 3 inch clay pot with charcol (each charcol is about 2 inches long) and a little coconut bark. Since the past six months, it has given 2-3 new leaves which became yellow and falled off. The older leaves, still remain and are bright green in color. I live in tropical humid climate. I water it every 7-10 days.

    My question is why are the leaves falling off? How long will it take for an orchid grown from tissue culture to bloom?
    Thanks!

    If the new leaves are turning yellow and falling off, maybe they are telling you that the orchid is getting too much water. Have you checked the roots of the orchid to see if they are still healthy? The older leaves will hold moisture longer than the newest leaves but eventually even they will fall off if the roots are damaged and failing.

    cheers,

    Hi BD,

    The roots look thin, dry and are brown-black in colour. I actually water them only once in 7-10 days. I live in Chennai, India which which has a tropical climate.

    Hi Chom, the reverse is also true. The roots could already be damaged. Take a look at this article and compare your plant to the ones featured here. Post a photo if you are able. Roots and All - Repotting
    and So, What is a Phal supposed to Look like?

    cheers,

    I don't think charcoal is a good medium for phals because it doesn't retain any moisture. Clay pots also cause the plant to dry quickly. You mentioned coconut bark. If you're talking about coconut husk chips, I would use more of that and just a little charcoal mixed in. I think you need a medium that will retain a little more moisture.

    Hi BD and tucker,
    The article on roots and all- repotting is just awesome. The small phal picture which is there, is what my orchid looked like when I removed it from its flask. The leaves were a little smaller. The roots looked the same. I will try and post some pictures of my phal.

    I don't get ready-made potting mix for orchids. I used charcoal (I didn't powder them) and a little fiber from coconut shell as the potting mix. How should I make the potting mix?
    Thanks.
