I've bought a hyacinth bulb and one of those hour glass vases for my little girl and can't remember whether I need to fill it up so that the water actually touches the bottom of the bulb?

Growing hyacinths in bulb vases
This is an alternative method for growing hyacinths. The bulb should be slightly smaller in diameter than the vase so that it sits snugly in the vase. Fill the glass with water to the neck and then place the bulb in the top. The water level should be just below the bottom of the bulb. The plant can then be treated in the same way as potted hyacinths (below).

Thanks Yorkie.

Used to do them with my Gran as a child!
