When you see the tulips breaking out of the soil and the roots coming out of the bottom of the pot, you can remove the potted bulbs and take them into the house to a bright, warm location to encourage growth of foliage and buds. I am going to let my bulbs go longer in the refrigerator because they are not ready yet. Tulips need 12 to 14 weeks of chilling at temperatures of 35 to 48 degrees with 40 degrees being ideal. Make sure that you do not keep apples in the refrigerator with your tulips. Apples produce an odorless gas called ethylene which will damage your tulip bulbs. Make sure you use a potting soil with fertilizer in it. Forcing does weaken the bulbs and you may not be able to rebloom them again in the garden. When you purchase bulbs, check to make sure that they can be forced. Potted bulbs with care instructions make great Christmas gifts for friends and fellow gardeners. I will keep you up to date on the progress of my bulbs - check back at "Garden Thyme with the Creative Gardener".
