When to Plant Dahlias in Michigan

Dahlias are a popular flower in Michigan, and for good reason. They come in a wide variety of colors, shapes, and sizes, and they can add a beautiful touch to any garden. But when is the best time to plant dahlias in Michigan?

The answer to that question depends on a few factors, including the type of dahlia you’re planting, your growing zone, and the weather.

Spring planting

If you’re planting dahlia tubers in Michigan, the best time to do so is in the spring, after the last frost. This will give the tubers plenty of time to grow roots and establish themselves before the summer heat sets in.

When planting dahlia tubers in the spring, it’s important to choose a location that gets full sun. Dahlias need at least six hours of direct sunlight per day to thrive. They also need well-drained soil, so make sure to amend your soil with compost or other organic matter before planting.

Summer planting

If you’re unable to plant dahlia tubers in the spring, you can also plant them in the summer. However, it’s important to note that summer-planted dahlias will not have as much time to grow and develop as spring-planted dahlias. As a result, they may not be as large or as showy.

When planting dahlia tubers in the summer, it’s important to choose a location that gets afternoon shade. This will help protect the tubers from the hot summer sun. You should also water your dahlias regularly, especially during hot and dry spells.

Fall planting

Fall planting is not recommended for dahlias in Michigan. The ground will start to freeze in late fall, and dahlia tubers will not have enough time to establish themselves before the cold weather sets in. If you do decide to plant dahlias in the fall, make sure to mulch them heavily to protect them from the cold.

Choosing the right dahlias for Michigan

When choosing dahlias for Michigan, it’s important to choose varieties that are hardy in your growing zone. The USDA hardiness zones for Michigan range from 4a to 6b. This means that dahlias that are hardy in zones 4a to 6b will be able to survive the winters in Michigan.

Some good dahlia varieties for Michigan include:

  • `Dahlia ‘Bishop of Llandaff’`: This variety is hardy in zones 4a to 6b and produces large, double flowers in shades of pink and white.
  • `Dahlia ‘Bishop of Auckland’`: This variety is hardy in zones 4a to 6b and produces large, single flowers in shades of red, orange, and yellow.
  • `Dahlia ‘Bishop of Oxford’`: This variety is hardy in zones 4a to 6b and produces large, semi-double flowers in shades of pink, red, and white.

Preparing the soil

Dahlias need well-drained soil to thrive. Before planting, amend your soil with compost or other organic matter to improve drainage and add nutrients. You should also work the soil to a depth of at least 12 inches.

Planting the tubers

Dahlia tubers should be planted about 4 inches deep and 12 inches apart. When planting, make sure to bury the eyes of the tuber (the small, pointed growths) so that they are facing up.

Caring for your dahlias

Dahlias need regular watering, especially during hot and dry weather. You should also fertilize your dahlias monthly with a balanced fertilizer.

In addition to watering and fertilizing, you should also deadhead your dahlias regularly. This means removing the spent flowers to encourage the plant to produce more blooms.

Dahlias are susceptible to a variety of pests and diseases, including aphids, powdery mildew, and botrytis. If you notice any pests or diseases on your dahlias, treat them immediately with the appropriate insecticide or fungicide.

Harvesting dahlias

Dahlias are ready to harvest when the petals are fully open and the blooms are starting to wilt. To harvest a dahlia, cut the stem just below the flower head.

Dahlias can be stored in a cool, dry place for up to two weeks. You can also dry dahlias for use in arrangements or crafts.
