How can I successfully grow bulbs in water vases?

To successfully grow bulbs in water vases, start by choosing a bulb that can grow in water, like paperwhites or hyacinths. Place the bulb in a vase with water, making sure the water covers the bottom of the bulb but doesn't touch it directly. Place the vase in a cool, dark place for a few weeks until roots start to grow. Then, move the vase to a sunny spot and change the water regularly. The bulb should start to sprout and bloom within a few weeks.
