Didn't disinfect roots when repotting Phalaenopsis orchids?

    Hello all. So yesterday I repotted two of my Phalaenopsis orchids which have suffered from root rotting, but I didn't disinfect them with hydrogen peroxide. I did cut the ugly roots and rinse them, but that is all. Should I be worried or will they be okay? If so, what should I do? Thanks in advance!

    I have been growing orchids since 1973, and have never disinfected roots when repotting. In my opinion, doing so achieves nothing.

    [Quote = "Maya, posta: 123.017, membro: 4233"] Ciao a tutti. Così ieri ho rinvasate due delle mie orchidee Phalaenopsis, che hanno sofferto di marciume radicale, ma non li ho disinfettare con acqua ossigenata. Ho tagliato le brutte radici e sciacquare, ma questo è tutto. Dovrei essere preoccupato o saranno a posto? Se è così, cosa devo fare? Grazie in anticipo! [/ Quote]

    If the roots have suffered from radical rot or collar rot, I would advise you to do a treatment (three to 10 days apart cycle) with Previcur Energy, active ingredient Propamocarb Fosetil 47.2% and 27.6%, a fungicidal in the ascending and descending sistemia, very effective

    I gotta tell ya. I just repotted a phal a pluro a masdy and a large Jewel Box and these are plants I neglected for a couple of years. No repotting only threw water on them. None of them had any roots in the pot. But you wouldn't know it from the way they looked. The Phal and the Catt.had some ariel roots. I don't know how the pluro's stayed alive. I hope I've Learned from this mistake but I also see that some orchids can really take the abuse.

    If you cut the roots above the root rot, and repot in fresh medium, that for the most part should be sufficient. I find that if the repotting is successful, the leaves plump up in the following few days. But as in the previous comment, I've bought orchids that looked really healthy, only to find that there are so few healthy roots left in the pot :( Helps to see inside and outside the pot.
