After a while, roots will appear, so gradually reduce the amount of water. It's fine if the tips of the roots are submerged in water. Once green shoots emerge from the top, place it near a window and give it some sunlight. If you get this far, it will grow bigger day by day and the flowers will bloom around spring.
