    Default SH update and question

    I've potted this guy into SH on June 24 since it was going crazy with roots and I didn't really like the sphag it was in (vast understatement). Now some roots have turned black but the new ones seem to be doing fine. I know it's the normal process of exchanging "water" roots for "dry" roots but should I pull it out of the pot and chop of the black roots or just leave it for now until it's compeletely established? I'm a bit worried about rot (obviously since that how I've specialized in killing phals).

    I've attached some pre and post pictures as well as some pics of the blackened roots. It had a great root system before so I wasn't too scared to try SH. Let me know what you think? (Yes, I hope that's a spike I cicled, but since it's making it's 2nd leaf in a row I highly doubt it).

    EDIT: This time I didn't just water before taking the pictures
    The first pictures is before changing to SH

    Richard, Are you flushing the organic matter out of the pot once a month or so? Actually, after potting my little phals in s/h, I flushed twice a month, now I'm down to once a month. To flush, I half fill a bucket with water from my dehumidifier, plunge the phal pot into it, swish the pot a bit, drain it and dunk it a few times, let it soak for up to 10 minutes to give any rotting organic material a chance to rise to the top, give it a final swoosh and drain. I'm counting on this to do at least two things for the phal, remove rotting organic matter and any buildup of fertilizer salts.

    Good idea! That should really help.

    I don't see any roots that you should cut off. Let it do its thing for now. JMHO.

    Most orchids will go through a transition period where the existing roots try to adapt to S/H, and also grow new roots that are tuned for the S/H environment.
    Some of the existing roots might adapt, but those that dont will die and rot away. But it will be hard to identify these roots until they are visibly dying already.
    It is important that you regularly flush out the S/H pot during this transition to prevent the build up of dead matter in the pot.

    I'm glad I read this thread. I'm experiencing the same thing with my recently transitioned phals.

    I always fill up the pot twice to the top and let the water drain out at the bottom. I do this about once each week. The darker roots are not mushy yet so I didn't worry too much. Plus the guy is putting out a new leaf and new roots so it must not be that damaged (if at all).
