Growing bleeding hearts (Dicentra spectabilis) can add a touch of elegance and color to your garden. Knowing the right time to plant them ensures healthy growth and vibrant blooms. This calendar provides guidance on when to start planting bleeding hearts based on your region’s climate.
Understanding the Bleeding Heart Plant
The bleeding heart is a perennial plant known for its distinctive heart-shaped flowers that dangle from arching stems. It thrives in shady, cool environments and prefers well-drained, rich soil. Proper timing in planting is crucial for establishing a healthy, long-lasting display.
General Planting Guidelines
Bleeding hearts can be planted from seeds or established plants. The timing depends on your climate zone, whether you are starting from seed indoors or planting outdoors. Below is a regional guide to help you determine the best time to begin.
Planting in Spring
In most regions, early spring is the ideal time to plant bleeding hearts outdoors. This allows the plant to establish roots before the heat of summer. In colder zones (USDA zones 3-5), wait until the danger of frost has passed, typically late April to early May.
Starting from Seeds Indoors
If you are starting bleeding heart seeds indoors, sow them 8-12 weeks before the last expected frost date. This usually means starting seeds in late winter, around February or March, to transplant outdoors in early spring.
Planting in Fall
In milder climates (USDA zones 7-9), fall planting can be successful. Planting in late September to October allows the plant to establish roots during the cooler months, leading to early blooms in spring.
Regional Planting Calendar
- North (Zones 3-5): Plant outdoors late April to early May; start seeds indoors February-March.
- Central (Zones 6-7): Plant outdoors March-April; start seeds indoors January-February.
- South (Zones 8-9): Plant outdoors October-November; start seeds indoors December-January.
Tips for Successful Planting
- Choose the right location: Shade to partial shade with well-drained soil.
- Prepare the soil: Mix in organic matter like compost for rich, loamy soil.
- Water regularly: Keep soil moist but not waterlogged.
- Mulch: Apply mulch to retain moisture and regulate soil temperature.
- Divide mature plants: Every 3-4 years in early spring to promote healthy growth.
Conclusion
Timing is key when planting bleeding hearts. By understanding your regional climate and following this calendar, you can enjoy these charming plants in your garden year after year. Happy planting!
