For all dahlia lovers digging up and storing your dahlia tubers in the fall is an annual ritual to ensure beautiful blooms next year. Properly doing so ensures you can enjoy these stunning flowers year after year. Removing dahlia tubers at the right time is just as important as knowing the proper technique for winter storage.
Here’s a step-by-step guide below, we teach you how to dig up and store your dahlia tubers to ensure they’ll bloom again next springtime:
Timing for Digging Up Tubers
After Frost:
Wait until after the first frost has blackened the foliage. This typically indicates that it’s time to dig up the tubers.
Digging Up the Tubers
Cut Back Foliage: Use pruners to cut back the stems to about 6 inches above the ground.
Carefully Dig: Use a garden fork or spade to gently lift the tubers from the soil, being careful not to damage them. Start digging a few inches away from the main stem to avoid cutting into the tubers.
Cleaning the Tubers:
Remove Excess Soil: Shake off excess dirt gently. Avoid washing the tubers with water, as this can lead to rot during storage.
Inspect for Damage: Check for any damaged or rotten tubers. Cut away any bad spots with a clean knife.
Curing the Tubers
Drying: Place the tubers in a warm, dry location out of direct sunlight for a few days. This helps to heal any cuts and reduce moisture, which can lead to rot.
Storing the Tubers
Choose a Container: Use a cardboard box, mesh bag, or a wooden crate for storage. Ensure there’s good airflow.
Add Bedding: Place the tubers in a layer of dry peat moss, sawdust, or shredded paper to help absorb moisture.
Keep Cool and Dark: Store the tubers in a cool (about 40-50°F or 4-10°C), dark, and dry place, like a basement or unheated garage. Avoid areas with extreme temperature fluctuations.
Checking During Storage
Regular Inspections: Check on the tubers periodically throughout the winter. Look for signs of rot or sprouting, and remove any affected tubers to prevent spreading.
Preparing for Planting
Pre-Planting Prep: A few weeks before the last frost, you can bring the tubers out of storage and inspect them. If they have any sprouts, you can pot them up in soil to encourage growth before planting in the garden.
By following these steps, you’ll help ensure that your dahlia tubers are ready to thrive in the next growing season! If you have any other questions about dahlias or gardening, feel free to ask!
