Dahlia Tuber Storage Tips
Dahlias are becoming an increasingly popular cut flower for flowers farmers and home gardeners alike. With many different colors, sizes and shapes, it’s easy to see why they’re a fan favorite! Dahlia flowers start from a tuber, which means that they have a swollen underground stem that stores energy for the plant to grow. While dahlias are not winter hardy in growing zones that have temperatures that dip consistently below 32 degrees Fahrenheit, their tubers can be dug up and stored over the winter months to be replanted in the spring. Proper dahlia tuber storage is essential to ensure that the tubers are healthy and ready to grow when the time comes to plant them again the following growing season. Today, we wanted to share some of our tips with y’all. Below are some tips for storing dahlia tubers throughout the winter
DAHLIA STORAGE TIPS
The best time to dig up dahlia tubers is after the first frost, when the plant has died back and the foliage has turned yellow. This usually occurs in mid October or early November.
Cut off the stems/greenery: Cut off the stems of the plants about 6 inches above the tubers, leaving a small stem attached to each tuber.
Clean and dry the tubers: Before storing the tubers, gently brush off any excess dirt, wash and allow them to air dry for a couple days in a well-ventilated area.
Once dry, divide dahlias and let sit out for another 24 hours.
Storage: Place tubers into peat moss as a storage medium in a ventilated box. We use bulb crates with craft paper liner on the bottom. A temperature of around 40-50°F is ideal, with the humidity kept around 80%, and plenty of airflow (we keep a fan running).
Protect from pests: It is important to check the tubers regularly for any signs of pests or rot. If you notice any issues, remove the affected tubers and dispose of them to prevent the problem from spreading. Common pests we see are roly-poly bugs. They will make a little village and eat your tubers. If you find them, take the entire crate out and rewash the tubers.
Check your tubers daily to make sure the temperature is within the range noted above, the humidity levels are correct and pull a few out to take a look at them from the peat moss (placing them back into and well under the peat moss aftterwards).
By following these simple steps, you can ensure that your dahlia tubers are properly stored and ready to be replanted in the spring. With a little bit of care and attention, you can enjoy these beautiful flowers in your garden for years to come.
