Dividing delphinium plants is a great way to propagate new plants and rejuvenate older ones. Proper storage of the divided sections ensures they remain healthy and ready for planting when the time comes. Follow these steps to store divided delphinium for future planting successfully.
Preparing the Divided Delphinium
After dividing your delphinium in early spring or late fall, carefully clean the roots to remove excess soil. Trim any damaged or weak roots with sterilized scissors. Keep the healthy roots intact to promote vigorous growth later.
Choosing the Right Storage Method
There are several methods to store divided delphinium for future planting. The most common include storing in a cool, moist environment or in a dormant state in a container. Select the method based on your available space and climate conditions.
Storing in a Cool, Moist Environment
Wrap the roots in damp sphagnum moss or peat moss. Place the wrapped roots in a plastic bag or container with ventilation holes. Store in a cool, dark place such as a basement or cellar, maintaining a temperature between 35°F and 45°F (2°C – 7°C).
Storing in a Container for Dormancy
Fill a container with moist sand, sawdust, or peat moss. Bury the divided roots in the medium, ensuring they are not touching each other. Keep the container in a cool, dark location with consistent moisture levels.
Maintaining Storage Conditions
Regularly check the stored roots for signs of drying out or rot. Keep the medium evenly moist but not waterlogged. If you notice any mold or decay, remove affected sections immediately to prevent spread.
Preparing for Planting
When the weather warms and the risk of frost has passed, prepare your garden bed. Gently remove the roots from storage, trim any damaged parts, and plant them at the appropriate depth. Water thoroughly to help establish the plants.
Additional Tips for Success
- Label each divided section to keep track of different varieties.
- Use sterilized tools to prevent disease transmission.
- Store roots in a consistently cool environment to prevent premature sprouting or drying out.
- Plant the divided delphinium as soon as conditions are suitable for best results.
By following these storage techniques, you can ensure your divided delphinium remains healthy and ready for planting season, helping you enjoy vibrant blooms year after year.
