Delphiniums are stunning perennial flowers that add height and vibrant color to gardens. However, their tall, slender stems are prone to flopping over, especially in windy conditions or heavy rain. Supporting your delphinium ensures it remains upright, healthy, and visually appealing throughout the growing season.
Understanding the Need for Support
Because delphiniums can grow over 6 feet tall, they require support to prevent damage. Without proper staking or caging, the weight of the blooms and external weather conditions can cause the stems to bend or break. Providing support not only protects the plant but also helps maintain an organized and attractive flower display.
Staking Techniques for Tall Delphinium
Staking is a straightforward method to support tall delphiniums. It involves inserting stakes into the ground and tying the stems to them as they grow. Here are some effective staking methods:
Single Stake Method
Insert a sturdy bamboo or wooden stake next to each plant, about 1-2 inches away from the stem. As the plant grows, gently tie the stems to the stake using soft garden ties or twine. Ensure the ties are not too tight to avoid damaging the stems.
Support Frames
For larger plantings, create a support frame using stakes or hoops. Connect the stakes with horizontal wires or netting, forming a cage around the plants. Tie the stems to the horizontal supports as they grow, providing stability and protection from wind.
Caging Techniques for Delphinium Support
Caging involves placing a wire or metal cage around the plant to support multiple stems simultaneously. This method is especially useful for dense or high-growing delphiniums.
Wire Cages
Use a wire cage with a diameter that comfortably fits around your plant. Place the cage around the delphinium early in the season before the plant reaches full height. Secure the cage into the ground if necessary, and gently tie stems to the cage wires for added support.
Netting Support
Stretch garden netting or mesh around the plant and secure it to stakes or the ground. This creates a flexible support system that can be adjusted as the plant grows. Tie stems loosely to the netting to prevent damage.
Additional Tips for Supporting Delphiniums
- Support early: Install stakes or cages before the plant reaches full height to prevent damage.
- Use soft ties: Avoid damaging stems by choosing gentle tying materials like twine or fabric strips.
- Regularly check supports: Adjust ties and supports as the plant grows to prevent constriction.
- Mulch around base: Mulching helps retain moisture and stabilizes the soil, reducing the risk of uprooting supports.
By employing proper staking and caging techniques, gardeners can enjoy tall, vibrant delphiniums without worry. Consistent support not only benefits the plant’s health but also enhances the overall beauty of the garden.
