Narcissus Bulb (Paper Whites)
To plant paperwhites, you will only want to plant the bulb about halfway in the soil so that the top half of the bulb is still exposed. These plants like bright light conditions and prefer to be watered thoroughly, however make sure the soil does not become soggy.
For growing paper whites in a vase, simply sit the bulb in the vase above the water. The bulb should not be sitting in the water. This allows just the roots of the bulb to touch the water. Place in a sunny location and be sure to replace the water if it gets too low or if it starts to look dirty.
