While it may seem counterintuitive, winter can be a great time to plant bulbs. The bulbs you buy now are in a state of dormancy and, when planted properly, will not suffer damage from spending time in the ground over the winter. In fact, they may actually benefit from the chill. Many early spring flowers come from bulbs that require a chill in order to bloom. It is a belief among many gardeners that as long as the soil is workable there’s time to plant bulbs. Most bulbs prefer well-draining soil in full sun to part shade, so choose your location carefully.
Tulip bulbs, lily bulbs, hyacinths, and more often require a period of chilling or they will not bloom the following season. Without a chill, they become annuals and die off. On the other hand, tender bulbs such as gladiolus bulbs need to be dug up before the true winter cold sets in or they will likely die off in a deep freeze. In hardiness zones, 4–7 early winter is an ideal time for planting spring-blooming bulbs. As a general rule spring-flowering bulbs should be planted in fall or winter, while summer flowering bulbs should be planted in the spring. When deciding which bulbs to plant when go by that rule and you will likely have success with your blooms.
Dig as deeply as you can when planting your spring bulbs and then cover the area with mulch to protect them. Don’t worry if you’ve already seen snow on the ground. As long as the ground itself is not frozen, they will likely grow roots.
Plants like tulips, lilies, and hyacinths often look their best in naturalized plantings. So plant tulips and the like in a random pattern with irregular groupings for the most impact. Choose various shades of similar colors such as blue, purple, or white flowers for a more refined look, or mix them all together for an even more natural feel.
These winter-loving bulbs often have blooms that make excellent cut flowers, so plant them thickly and they can be thinned out for bouquets without sacrificing the overall look come spring.
