Hello - I have a Christmas Cactus that I've somehow kept alive for over a year now. ;) It's beginning to look as if it's too big for the original plastic pot it came in. I would like to transfer it to a little larger pot but I don't want to kill it. I'm not very plant-savvy...could someone please tell me what soil I need to purchase to repot the cactus? Is there anything else I need to be aware of when repotting? Thank you for all helpful responses.

I'm in the DFW, Texas area and have a 50 foot line of evergreen shrubs that have green (mixed with yellow) leaves (new growth is more yellow). They stand about 6 feet tall and I do prune their height and width back every year. They also sprout new growth from the roots. Almost all the shrubs in the line have a white thin oblong thing, almost looking like someone sprinkled the top of the leaves with spiny salt.

What can I do about these things?
