Audrie, You do like it says in the post above, twist them off....and how far down and how much is up to you depending on how big your plant is. You want to just trim it so it looks good, then you would have to know how much to take off by looking at it.
Some people leave them callas over a few days and then dip them in rooting gel or powder and plant them immediately in a good potting soil. Others put them in water and let them root in water, when the roots get to a certain length, plant them. Some people do not even let them callas over. They just plant them when they remove them. They will pretty much grow no matter how they are started if they are not over watered and have good soil and drainage.
Be sure your pot is not too big. The smaller the pot the better the root system will grow and strengthen. Depends on how many cuttings you put in the pot. There again, it is up to you.
