How to Dig Up Dahlia Tubers: A Guide
How to Dig up Dahlia Tubers?
To dig up dahlia tubers, start by waiting until after the first frost has killed the foliage.
Once the foliage is dead, cut it back to about 6 inches above the ground.
Then, use a garden fork or spade to carefully dig around the perimeter of the plant, gradually working your way inward to avoid damaging the tubers.
Gently lift the clump out of the ground and shake off any excess soil.
Rinse the tubers with water to remove any remaining dirt.
Allow the tubers to air dry for a day or two in a cool, dry place.
Once dry, trim any remaining foliage and loosely pack the tubers in a box or crate filled with dry peat moss or vermiculite.
Store the tubers in a cool, dry area, such as a basement or garage, where temperatures stay around 40 to 50 degrees Fahrenheit.
Replant the tubers in the spring, after the danger of frost has passed, to enjoy beautiful dahlia blooms once again.

3. Did you know that dahlia tubers can range in size from as small as a golf ball to as large as a grapefruit?
4. To properly dig up dahlia tubers, use a garden fork or spade to gently loosen the soil around the plant, taking care not to damage the tubers.
5. Once the dahlia tubers have been dug up, they should be stored in a cool, dry place for the winter, preferably in a cardboard box filled with sawdust or vermiculite to maintain their moisture levels.
Introduction: Dahlia Tubers – A Gardener’s Prize
Dahlias are a gardener’s delight, known for their stunning and vibrant blooms that add beauty to any garden. These popular flowers come in various shapes, sizes, and colors. However, the challenge for dahlia enthusiasts is the sensitivity of these plants to freezing temperatures in winter. To preserve these treasured plants and enjoy their blooms year after year, it is important to understand the process of digging up and storing dahlia tubers.
Dahlia Facts: Large, Colorful Blooms and Winter Sensitivity
Dahlias are known for their large and colorful blooms that attract both gardeners and flower enthusiasts. They offer a wide range of hues, from soft pastels to bold and brilliant shades, making them a perfect option for adding vibrant colors to any garden bed or container. However, it is crucial to remember that dahlias are not winter hardy and cannot withstand freezing temperatures. Therefore, without adequate care, these beautiful flowers will not survive the harsh winter conditions.
Digging And Storing Dahlias: Easy Steps For Winter Care
Fortunately, digging up and storing dahlia tubers for the winter is a relatively straightforward process that any gardener can accomplish, ensuring the survival of these stunning plants.
The first step is to wait until after the first frost when the dahlia plants begin to turn black and wilt. This signals that it is time to dig up the tubers. Begin by carefully excavating around the plant, taking care not to damage the delicate tubers.
Once the tubers are exposed, gently lift the clumps from the ground and shake off any excess soil. It is important to handle the tubers with care, as they are delicate and susceptible to bruising or injury.
After removing the excess soil, trim away any remaining foliage, leaving only about an inch of stem attached to the tubers. This will help prevent rot during storage.

Replanting In Spring: Ensuring Continued Flowering
To ensure the successful replanting of dahlia tubers in the spring and the continuation of their stunning blooms, it is important to follow these steps:
-
Inspect and Sort: Before replanting, carefully examine the tubers for any signs of damage or decay. Discard any tubers that appear shriveled, soft, or have visible rot. On the other hand, healthy tubers should appear firm and plump.
-
Divide: To promote new shoot growth, divide the tubers before replanting. Each tuber division should have an eye, which is a small bud that will sprout into a new plant.
-
Protect: Dusting the tubers with a fungicide will help prevent rot and other diseases, ensuring their future health.
-
Choose the Right Location: When it’s time to plant the tubers, select a location that receives a minimum of six to eight hours of sunlight per day. Dahlias thrive in sunny areas.
-
Prepare the Hole: Dig a hole that is large enough to accommodate the tuber division. Make sure to plant it with the eye facing upwards.
-
Cover and Water: Cover the planted tuber with soil, leaving about two inches of soil above it. Water the tuber thoroughly after planting.
By following these guidelines, your dahlia tubers will have the best chance of successfully regrowing and producing beautiful blooms in the upcoming season.
Dahlia Background: Native To Mexico And South America
The dahlia is a flower with a rich history, native to Mexico and South America. It gained popularity in the early 19th century when Spanish explorers discovered these stunning flowers growing wild. They were then brought back to Europe, where they quickly gained recognition for their beauty and diversity.
Throughout the years, dahlias have undergone extensive hybridization and breeding. This has led to the creation of an incredible array of colors, shapes, and sizes for these flowers. There is a dahlia variety available for every gardener’s taste, ranging from small and delicate ‘pompon’ dahlias to the giant ‘dinner plate’ cultivars.

Frequently Asked Questions
When should dahlia tubers be dug up?
It is best to wait until the top growth of dahlia tubers dies back or is killed by the first hard frost before digging them up. This ensures that the tubers have enough time to fully develop before being unearthed. Even if the foliage appears dead, it is important to wait, as the tubers will continue to grow for a while longer. By timing the digging of dahlia tubers based on the condition of their top growth, you can ensure that you are harvesting them at their optimal stage of development.
How do you force dahlia tubers to sprout?
To force dahlia tubers to sprout, it is essential to create a conducive environment. Begin by placing the tubers in a greenhouse or a sunny windowsill to ensure they have access to sunlight. Maintaining soil temperatures at or above 60 °F/ 16 °C is crucial for their growth. By providing these optimal conditions, the dahlia tubers will be encouraged to sprout and thrive.
Do dahlias need full sun?
Yes, dahlias thrive when planted in full sun, receiving a minimum of 6 to 8 hours of direct sunlight each day. This ample sun exposure allows the plants to produce an abundance of colorful blooms that can be enjoyed all summer long. To encourage even more flowering, regular cutting of the flowers can be done, as it stimulates the plant to produce even more blooms.
Do dahlia tubers need water?
Yes, dahlia tubers require water, but it is essential to strike a balance. Initially, when planting the tubers, a good amount of water is necessary to facilitate sprouting. However, after the initial watering, it is crucial to refrain from excessive watering as it can lead to tuber rot. Finding the perfect balance of moisture will contribute to the successful growth of dahlia tubers.
