Dividing delphinium is a common gardening task that can help rejuvenate plants and promote healthy growth. However, many gardeners make mistakes that can harm the plant or reduce its flowering potential. Knowing what to avoid can ensure successful division and a vibrant garden.
1. Dividing at the Wrong Time
Timing is crucial when dividing delphinium. The best time to divide is in early spring or late fall, when the plant is dormant. Dividing during the active growing season can stress the plant and hinder recovery.
2. Using Improper Tools
Using dull or inappropriate tools can crush or damage the delicate root system. Sharp, clean garden spades or knives are recommended for clean cuts that promote healthy healing.
3. Dividing Too Deep or Too Shallow
Removing too much soil or cutting too deep can harm the plant’s crown. Aim to divide the plant into sections that include healthy roots and a portion of the crown, typically about 3-4 inches apart.
4. Ignoring Root Health
Healthy roots are vital for successful division. Avoid dividing plants with rotted, diseased, or damaged roots. Healthy roots should be firm, white or light-colored, and free of rot or pests.
5. Not Providing Proper Aftercare
After dividing, delphinium sections need proper care to recover. Water thoroughly, mulch to retain moisture, and avoid fertilizing immediately. This helps the new divisions establish quickly and reduces stress.
