To plant dahlia tubers, you must establish the spring-blooming bulbs before the cold dormancy they require begins. Roots will develop rapidly from the bottom, and stems will sprout from the top later on. If possible, avoid planting when there is a sufficiently long warm spell to sprout from the soil. If the air and soil temperatures are cold enough, the stem buds will only grow to just below the surface, and will stop when the soil temperature drops further due to freezing temperatures.

Once nighttime temperatures are consistently between 40 and 50 degrees Fahrenheit, but before the first hard frost, the spring bulbs can be planted. The soil will be cool enough to achieve optimal rooting. The bulbs should be planted about six weeks before the ground freezes. Bulbs that have enough time to root will also undergo a natural process that prevents them from freezing.
After the ground freezes, apply 2-4 inches of mulch to maintain a more stable soil temperature. Mulch also prevents rapid thaw/freeze cycles in early spring, which can push your bulbs up out of the ground. If your region experiences extreme climates or rapid changes, such as the Great Lakes or northern regions 1 - 3, you may want to choose bulbs that bloom later and are less likely to be affected by late frosts.
Summer-blooming dahlia bulbs, including rhizomes, corms, tubers and tuberous-rooted plants, can be planted in spring once the soil begins to warm up. Hardier summer-blooming bulbs such as irises and daylilies can be planted very early and are not bothered by cool soil. More temperature-sensitive bulbs, such as begonias, dahlias, gladioli, tropical cannas and fritillarias, prefer to wait until the spring soil is fairly warm.
