Delphiniums, with their towering spires of vibrant blooms, are a beloved addition to any garden. But are these majestic flowers a “cut and come again” variety? Can you enjoy their beauty twice, once in the garden and again as stunning cut flowers? The answer is a resounding *yes*, but with a few important considerations.
Delphinium Cut and Come Again: The Basics
The “cut and come again” concept refers to plants that can be repeatedly harvested for their flowers without compromising their overall health and growth. Delphiniums, while not strictly “cut and come again” in the same way as, say, zinnias, can be managed to provide a second flush of blooms. The key is understanding the plant’s growth cycle and how to encourage it to produce new flowers.
The Secret to a Second Flush of Blooms
Delphiniums are typically biennial, meaning they complete their life cycle in two years. In the first year, they focus on building a strong root system and foliage. The following year, they produce their impressive flower stalks. Here’s how to encourage a second flush of blooms:
- Timing is Key: The best time to cut delphiniums for a second bloom is after the first flush has faded but before the seed pods have started to form. This ensures the plant has enough energy to produce new flowers.
- Cut Below the First Set of Buds: When cutting your delphiniums, make sure to cut the stem below the first set of flower buds. This allows the plant to focus its energy on producing new blooms, rather than wasting it on seed production.
- Deadheading: Regularly removing spent blooms (deadheading) will encourage the plant to produce more flowers.
- Fertilize: Provide your delphiniums with regular fertilizer to ensure they have adequate nutrients for continued growth and flowering.
- Water: Delphiniums thrive in moist soil, so make sure to water them regularly, especially during hot, dry weather.
Understanding the “Cut and Come Again” Limitations
While delphiniums can produce a second flush of blooms, it’s important to remember that this isn’t guaranteed. Factors such as heat, drought, or pests can affect the plant’s ability to rebloom. Additionally, the second flush of blooms will often be smaller and less impressive than the first.
