I have a zygopetalum that is growing in a straight line with it reaching the limits of a 7 inch pot. Now that new growth is occuring, I would like to know how I should repot it. Can I divide it and put the back bulbs in another pot and start a new plant? Should it be tightly potted? It dropped its leaves when I repotted a couple of years ago and hasn't bloomed since. Now I am growing it under lights inside all year. Temps are typically 75 during the day and 62 at night with 60% humidity. I would included pictures, but this site gives me an error message only stating that there was an error in loading the image. Odd, since it is a jpeg file and I compressed it to only 2 mb Open to suggestions on both issues.
