Learn how to force tulips to bloom inside with this step-by-step tutorial. Tulip bulbs need a chilling period between 14-19 weeks depending on the particular variety.
Stick the bulbs in a brown paper bag in the crisper drawer of your refrigerator for the chilling period. Take care not to place them near apple or pears that emit ethylene gas. After the chilling period pot them up in a container with a drainage hole and water them in. Place in a dark cool place that is approx 50 degrees F to root into the soil.
After the rooting period take them out of darkness and place them in an area with bright indirect light. The tulips will bloom in about 3-4 weeks.
