Choosing the Right Time to Store Dahlia Tubers

Timing is crucial when it comes to storing dahlia tubers. It is important to wait until after the first frost has occurred before digging up the tubers for storage. The first frost acts as a signal for the dahlia plants to go into dormancy, making them more resilient and better suited for storage.

Typically, late autumn or early winter is the ideal time to start the process of storing dahlia tubers. By this time, the plants have finished flowering, and the foliage has started to turn yellow or brown. The tubers have fully matured and are ready for storage.

One way to determine if it’s the right time to store the tubers is to check the soil temperature. You can use a soil thermometer to measure the temperature of the ground. If the soil temperature consistently stays below 50°F (10°C), it is a good indication that it is time to dig up the tubers.

It’s important to remember that if you live in a region with mild winters, where the ground doesn’t freeze, you may need to adjust your storage timing accordingly. In such cases, you can wait until the foliage has completely died back, and the soil temperature has cooled down to a suitable level for storage.

By waiting for the right time to store dahlia tubers, you allow the plants to naturally transition into dormancy, which helps them survive the winter and regrow in the following spring. If you store the tubers too early or too late, there is a higher chance of damage or disease affecting the stored tubers, leading to reduced success in the next growing season.
