Can dead roots and new roots co-exist?
 

I have several Phals that I repotted about a month ago in bark mix for Phals in clear posts. I can see bright green roots growing but also see some crummy dead roots if I move the top of the medium a tad. Do I do another repot and trim away the dead roots? Inquiring mind needs to know from the experts. :)

As long as it's not blooming, it won't hurt to repot. Besides, removing dead tissue will be healthier for the plant, dead tissue attracts fungus and pests. Make sure you sterilize your cutting tools in between plants....preferably with open flame.

Great suggestion Jasen, would do chid surgery on the rooting system, can only help the health of the orchid. Remember use fresh medium no matter how short of a period between repotting. Like fresh linen:evil:

Just to ad another view, I have left the old brown roots with no ill affect. While I don't recommend it, it shouldn't cause any ill-will.

If the root environment is good, the rot on one root will no proliferate. Keep in mind that root death leads to rot, not the other way around.

Supporting Ross' observations, when you move a plant from a dry root environment into semi-hydroponics, we expect to have the old roots die. When they do, they eventually decompose - releasing what little bit of stored nutrition they have - and if your watering regimen is sufficiently thorough and frequent, the little bits wash out of the pot. All with no detriment to the plant at all.

Thanks folks. Will tend to them one at a time with your suggestions.
