Tulips require at least 8
Tulips require at least 8 weeks of cooling before they will grow. You can try keeping the bulbs planted in soil in a conatiner in the refrigerator for a few weeks and then planting them the ground, but this method would have been better if started in December. Tulips are a spring-flowering plant though some tulips do last until early summer. Tulips will return for many years, but do eventually stop producing blooms.
