Phlox is a popular perennial plant known for its vibrant flowers and fragrant blooms. Properly storing phlox tubers over winter is essential to ensure healthy growth in the following season. This guide provides the best practices for storing phlox tubers safely during the cold months.
Preparing Phlox Tubers for Storage
Before storing, it is important to prepare the tubers properly. This involves harvesting, cleaning, and curing the tubers to prevent rot and disease.
Harvesting the Tubers
Wait until the foliage has turned brown and died back naturally. Carefully dig around the plant to lift the tubers without damaging them. Shake off excess soil and inspect for any signs of disease or damage.
Cleaning and Curing
Gently rinse the tubers with water to remove remaining soil. Allow them to dry in a well-ventilated, shaded area for about a week. Curing helps toughen the skin and reduces the risk of rot during storage.
Storage Conditions
Proper storage conditions are vital to keep phlox tubers healthy and viable for planting in spring. Maintain a cool, dark, and dry environment to prevent sprouting and decay.
Ideal Temperature and Humidity
The optimal temperature for storing tubers is between 35°F and 40°F (2°C – 4°C). Keep humidity levels low to prevent mold and rot, ideally around 50%.
Storage Containers
Use breathable containers such as paper bags, mesh bins, or cardboard boxes. Avoid plastic bags that trap moisture and promote mold growth.
Regular Inspection and Maintenance
Check stored tubers periodically during winter. Remove any that show signs of rot, mold, or sprouting. Proper ventilation and maintaining optimal conditions help prolong storage life.
Preparing Tubers for Spring Planting
As spring approaches, gradually reintroduce the tubers to warmth and light. Before planting, cut away any damaged sections and allow cuts to callus for a day or two to prevent infection.
Conclusion
Storing phlox tubers over winter requires careful preparation and the right storage conditions. By following these best practices, gardeners can ensure healthy, vigorous plants come springtime, enhancing their garden’s beauty year after year.
