Hi Becky! Be sure to re-size your photos before trying to post them here. They need to be under 700 pixels each way before it will let you load them. Old leaves are necessary for the continued well being of the plant. I think the reason the roots grow up into the air is because most phals "in the wild" grow facing downward, with the roots growing up. Your plant is just trying to get back to what is "normal" for it.
