Is this your orchid or a u tube video? Can't give advice without seeing the plant.

This is my cattleya that I bought on ebay a couple of years ago. It came from Washington state and was obviously grown in a greenhouse and had a flower when it arrived. It hasn't flowered since. I've done other videos on it. It's my first and only cattleya. I'm not having as much success with this as I do with my phalaenopsis.

Can you give more information? I'm confused by your video. Did you cut all those roots off?

Please post back, tell us where you live (zone, Country, State). What type of conditions is your plant getting, (light exposure, temps, watering and potting media).

This is not the best time to repot an orchid. Spring is best unless you live in a warm climate.

I live in Florida and will do repotting in Spring when the daylight hours increase.
