General rule for houseplants:

Let the dirt dry down to just barely moist below the surface between
watering.

Tapwater is OK, but you should let it stand a day or two in an open
container before using for watering. This allows the chlorine to gas out.

Every year or two, you should take the plant outside, and soak it
thoroughly to the point of water dripping out the bottom. This will
flush the accumulated salts out of the dirt.

There are a number of good books on houseplant care. Buy one at your
garden centre or bookstore, or borrow from your local library.
