MaximumYield explains bulb forcing
According to gardeners, there are two different types of bulbs that can be used for indoor growing. During bulb forcing, some bulbs need to be chilled, while others can grow comfortably at room temperature. These mainly include native tropical bulbs such as Paperwhite Narcissus and Amaryllis. When forcing these bulbs, it is important to grow them in a shallow bowl filled with pebbles. Alternatively, you can also grow these kind of bulbs in a soil-filled pot.
Some bulbs- especially spring ones- absolutely need to be chilled so they can properly bloom. These plants include Scilla, Dutch Iris, Crocus, Hyacinths, Daffodils and Tulips. Such flowers need to be exposed to at least 18 weeks of cold, after which they can be exposed to warmth.
