Delphiniums, with their towering spires of vibrant blooms, are a beloved addition to any garden. But what happens when the season ends and the flowers fade? Knowing how to store delphinium bulbs properly is key to ensuring their survival and a triumphant return next spring. This guide will equip you with the knowledge needed to safeguard your delphinium bulbs, ensuring a vibrant display of color for years to come.
Understanding Delphinium Bulbs
While delphiniums are often referred to as having bulbs, they actually grow from tuberous roots, which are thick, fleshy roots that store nutrients and allow the plant to survive the winter. These tuberous roots are similar to bulbs in their function, but they have a different structure. Understanding this distinction is important when it comes to storing them.
The Importance of Proper Storage
Storing delphinium bulbs correctly is crucial for their survival. Improper storage can lead to:
- Rotting: Excess moisture can cause the roots to rot, leading to their demise.
- Drying Out: Too little moisture can dehydrate the roots, making them unable to sprout in the spring.
- Pest Infestation: Improper storage conditions can attract pests, which can damage the roots and prevent them from growing.
When to Dig Up Your Delphiniums
The optimal time to dig up your delphinium bulbs is after the first frost. This usually occurs in the fall, when the foliage has died back. Avoid digging them up too early, as the roots will still be actively growing and storing energy.
Preparing Your Delphinium Bulbs for Storage
1. Digging: Carefully dig around the base of the plant, using a garden fork or shovel to loosen the soil.
2. Cleaning: Gently brush off excess soil from the roots.
3. Drying: Allow the roots to air dry in a cool, shady place for a few days. This will help to prevent them from rotting in storage.
Choosing the Right Storage Method
There are two main methods for storing delphinium bulbs:
- Dry Storage: This method involves storing the bulbs in a cool, dry, and well-ventilated space.
- Moist Storage: This method involves storing the bulbs in a slightly moist medium, like peat moss or vermiculite.
Dry Storage: A Simple and Effective Method
1. Choosing a Container: Select a container made of breathable material, such as a cardboard box or paper bag. Avoid using plastic containers, as they can trap moisture and lead to rotting.
2. Preparing the Storage Area: Choose a cool, dry, and dark place for storage. A basement or garage is ideal, as long as it doesn’t freeze.
3. Placing the Bulbs: Spread the bulbs out in a single layer in the container, making sure they are not touching each other. This will help prevent them from rotting.
4. Labeling: Label the container with the type of delphinium and the date of storage.
Moist Storage: A More Involved Approach
1. Choosing a Medium: Peat moss or vermiculite are suitable mediums for moist storage.
2. Preparing the Medium: Moisten the medium slightly, but avoid making it soggy.
3. Placing the Bulbs: Gently place the bulbs in the prepared medium, ensuring they are not touching each other.
4. Storing: Place the container in a cool, dark, and well-ventilated space.
5. Monitoring: Check the moisture level regularly and add more medium if it becomes dry.
Preventing Pests and Diseases
1. Inspection: Inspect the bulbs before storing them for any signs of pests or diseases.
2. Treatment: If you find any pests or diseases, treat the bulbs with an appropriate insecticide or fungicide.
3. Pest Control: Keep the storage area clean and free of debris to prevent pest infestations.
