Does a plants soil ever need to be replaced?
Like a potted household plant. Do you ever need to change their soil?

Once a year scrape out about 3 or 4 inches of soil if a big pot. If a small pot about 2 inches or so and add some compost. This will enrich the soil. If you fertilize a lot you build up salts in the soil and may have to change soil. That is the white you sometimes see on clay pots. Also the plant may outgrow the pot, the only way to know is to remove from pot and see if roots fill it. Then you will have to move to bigger pot. Some plants though don't flower unless "Pot Bound", like Christmas Cactus. Google your plant and find out what to do for potting. eHow.com is a good site for that kind of stuff.

Well you'd damage the roots if you tried and you'd kill the plant.
If you're replacing the plant with a new plant and it's 3-5 years old, I've seen recommendations to replace it. But I've used soil much longer than that so it's probably not necessary.

Yes. But hardly ever.
