Fertilizing your bleeding heart (Dicentra spectabilis) after deadheading is essential to promote healthy growth and vibrant blooms. Proper fertilization ensures that the plant remains vigorous and continues to produce its characteristic heart-shaped flowers year after year.
Understanding Bleeding Heart Needs
Bleeding hearts thrive in rich, well-drained soil with consistent moisture. They prefer shaded to partially shaded locations and benefit from regular feeding during the growing season. Deadheading, or removing spent flowers, encourages the plant to focus energy on new growth and flowering.
When to Fertilize
The best time to fertilize bleeding hearts is in early spring and again after the deadheading process. This timing supports new growth and prepares the plant for the upcoming flowering period.
Early Spring Fertilization
Apply a balanced fertilizer, such as a 10-10-10 or 20-20-20 formula, when new shoots begin to emerge. This provides essential nutrients to kickstart healthy growth.
Post-Deadheading Fertilization
After removing spent flowers, feed the plant with a liquid or granular fertilizer high in phosphorus, such as a 10-20-10 formula. This encourages the development of new flower buds and strengthens the plant for future blooms.
Recommended Fertilizer Recipes
- Homemade Organic Fertilizer: Mix 1 cup of composted manure with 1 gallon of water. Let it steep for 24 hours, then strain and apply around the base of the plant.
- Banana Peel Tea: Boil banana peels in 2 cups of water for 10 minutes. Cool and use as a liquid feed to provide potassium and other nutrients.
- Fish Emulsion: Dilute fish emulsion according to package instructions and apply every 2-3 weeks during the growing season.
Application Tips
Always water the soil before applying fertilizer to prevent root burn. Apply fertilizers evenly around the base of the plant, avoiding direct contact with the foliage. Consistent, moderate feeding yields the best results without overloading the plant.
Common Mistakes to Avoid
- Over-fertilizing, which can lead to lush foliage but fewer flowers.
- Applying fertilizer late in the season, risking new growth that may be damaged by frost.
- Using high-nitrogen fertilizers exclusively, which encourages leafy growth at the expense of blooms.
By following these fertilizing recipes and tips, your bleeding heart will reward you with abundant, vibrant blooms season after season. Proper care and feeding are key to maintaining a healthy and beautiful plant.
