    Default Best Time to Repot a Cattleya?

    From what I've read the best time to repot a Cattleya is right after it blooms or when new roots are forming. I have a few that I repotted a few years ago that need new bark mix. The other issue is the last time I repotted I wasn't experienced enough to realize that you have to cut off all dead roots. I can see dead roots in the pots (I use clear plastic pots). All of the catts have active root ends now and some are growing new roots. Is it okay for the plant to repot now or should I wait until the spring? Thanks!

    Lightbulb Repotting a Cattleya Orchid

    The best time to repot: We repot in late spring and early summer before the onset of vigorous new growth. Since roots that have been growing exposed to the air for any length of time will most likely die when packed beneath the bark surface, try to repot just as new growth is beginning to appear. If you waited too long and your plant is already well into its new season, hold off until after your orchid has bloomed, otherwise you will lose that growth’s flowers and you’ll run the risk of killing the plant’s entire new root system.

    Repotting should be done every year-and-a-half to two years, before the potting medium begins to break down into peat and loam. Waiting longer than two years allows the broken-down medium to retain too much moisture, keeps the roots from receiving any air circulation, and will contribute to the onset of root rot.

    I agree with Bruce. Never repot a Catt. unless it is in new active growth, nice little short roots beginning. They will transfer better to the new bark than old roots which will likely break or squash. I lost several nice Catts. before I wised up to this requirement. They will tell you when it is time. Also, I pay attention to the water coming out the bottom of the pot. When the bark starts coming out like coffee grounds, you know the bark is breaking down and needs to be replaced.
