Delphiniums are stunning perennial flowers that add height and vibrant color to gardens. To ensure they produce strong, tall, and vibrant blooms, gardeners often turn to specialized fertilizers. One popular option is bone meal, a natural fertilizer rich in phosphorus and calcium. This article guides you through the process of using bone meal effectively to enhance your delphinium blooms.
What Is Bone Meal?
Bone meal is a slow-release organic fertilizer made from ground animal bones. It is high in phosphorus, which promotes healthy root development and flowering, and calcium, which strengthens plant cell walls. Because of its nutrient profile, bone meal is particularly beneficial for flowering plants like delphiniums.
When to Use Bone Meal for Delphiniums
The best time to apply bone meal is during planting and early in the growing season. You can also top-dress established plants in early spring or after the first bloom cycle. Avoid applying during the flowering period to prevent excessive foliage growth at the expense of blooms.
Preparing the Soil
Before planting delphiniums, prepare the soil by mixing bone meal into the planting area. Use approximately 1 to 2 tablespoons of bone meal per square foot of soil. Mix it thoroughly into the top 6 inches of soil to ensure even distribution and optimal nutrient availability.
Applying Bone Meal to Established Plants
For existing delphiniums, sprinkle a thin layer of bone meal around the base of each plant, avoiding direct contact with the stems. Water the area thoroughly after application to help nutrients penetrate the soil and reach the roots.
Additional Tips for Healthy Delphiniums
- Ensure well-drained, fertile soil with a slightly alkaline pH.
- Provide support with stakes or cages as delphiniums can grow tall and may topple in wind.
- Water consistently, especially during dry spells, to keep the soil moist but not waterlogged.
- Deadhead spent blooms to encourage continuous flowering.
- Apply a balanced fertilizer during the growing season for overall plant health.
Precautions When Using Bone Meal
While bone meal is a natural fertilizer, avoid over-application as it can lead to excessive foliage growth and reduced flowering. Keep it away from pets and children, as ingestion can be harmful. Always follow the recommended application rates for best results.
Conclusion
Using bone meal is an effective way to promote strong, vibrant delphinium blooms. Proper timing and application ensure your plants receive the necessary nutrients for healthy growth and stunning flowers. Incorporate bone meal into your gardening routine to enjoy a spectacular display of these majestic flowers each season.
