How to cure root rot?

[boxerfan]

One of my phals. looks like it is developing some root rot. About half of its roots are plump, greenish-white. Towards the ends half are withered grayish-brown. I am brand new to orchids (and most plant care) what do I do. I've already cut holes in all of my pots to increase aeration. TIA Lisa

Dear boxerfan,

Unfortunately root rot can not be cured. while a plant will grow new roots, rotted ones can not regenerate.

Root rot is frequently caused by overwatering, especially in the case of Phals. You mention you have some healthy roots, which is good. Your plant will probably survive and grow new roots toreplace the rotted ones. Take a look at yourpotting mix. It is possible it is retaining too much moisture. It's also possible you're watering too much.

Are the withered grayish-brown parts mushy? If so, then cut them off with a sterilized tool. You could then pack cinnamon into the cut parts to prevent any further damage.

IMHE its phals that are planted in spaghnum moss that develop root rot problems

The sick looking phals that i was given had some of that problem but after removing dead or decayed roots and repotting in a different medium plus misting with worm tea mixture they are all now looking good

Not the sphagnum moss is to be blamed, but over watering.
Sphagnum is a great medium if you are able to handle it (and control moisture).

Well, two of my plants had significant root rot and both were under warranty. I returned them and picked out two plants with healthy roots (I checked). Unfortunately, my Harlequin Phal. needed to go, so I'll be on the lookout for a new, healthy one. Thanks for the Root Rot info. I've cut holes in all of the plastic pots to help the roots and potting material to air out. Lisa

Lisa, you might consider the skewer method of watering. Get some shishkabob skewers from the grocery store. Trim one down and slip it into the pot and keep it there. The next time you think the plant needs water take out the skewer and touch it to your lip, cheek or hand. If the skewer is wet, don't water. If the skewer is dry, or in the case of phals, nearly dry, water. How wet or dry the stick is before you water will depend on what type of orchid it is.
