Our pre-chilled bulbs will be ready for shipping when they have received 12 weeks of the required cold temperatures. Pre-chill bulbs are great for forcing indoors, as well as for climates where consistently cool temperatures are not available. Tulips need 12-16 weeks of consistently cold temperatures (under 50 degrees during the day in order to bloom)
*Our pre-chilled bulbs are ready for shipping starting in mid-December. By this time they have received the minimum amount of cold temperatures required for forcing and flower bud production.*
You can complete this "forcing" process indoors or
out. If you need more help on forcing, please refer to our help
section it has everything you need to successfully force flower bulbs!

If you have received your pre-chilled bulbs in early December, they may need 4 more weeks of chilling. After January the bulbs will have received 12+ weeks of chilling, and do not require any additional chilling. If you are not able to plant your bulbs immediately upon receiving them, it is important to continue chilling them in cold storage such as a refrigerator, cold garage or cold shed until you are able to plant.
