Forcing bulbs: “Forcing is a technique that imitates the environmental conditions that bulbs encounter outdoors, thereby tricking them into flowering earlier.” Beginner’s Guide to Forcing Bulbs
Another way to enjoy Spring bulbs is to force Hyacinths. The same protocol applies to these bulbs, place them in a cold place for at least twelve weeks before forcing. I bring my Hyacinth bulbs into bloom by using a special vase, named quite appropriately, a Hyacinth Vase.
In my experience, the plant usually becomes top-heavy if I allow it to continue growing in water. When the beautiful blooms open their bulk causes the bulb to topple out of the vase. To counteract this problem I have begun planting the bulb in dirt when it nears bloom time. This has worked very well for me. Happy Gardening!
