Reblooming bigleaf hydrangeas (hydrangea macrophylla) are a stunning addition to any garden, blooming on both old and new wood, which allows for an extended flowering season. Unlike traditional hydrangeas that only bloom on old growth, these beautiful varieties offer a continuous display of color, making them a favorite among gardeners.
Why Choose Reblooming Bigleaf Hydrangeas?
Reblooming bigleaf hydrangeas have revolutionized the way we think about landscaping. With their ability to produce flowers multiple times in one season, they offer unique benefits:
- Prolonged Blooming Season: The most evident advantage is their extended blooming period. Traditional varieties bloom once in early summer; reblooming types can provide flowers from spring through fall.
- Versatile Color Options: The blooms can change color based on soil pH, allowing gardeners to create a more personalized aesthetic.
- Maintenance Ease: Once established, they require minimal care, making them suitable for busy gardeners.

Best Growing Conditions
Location and Light
Reblooming bigleaf hydrangeas thrive best in partially shaded areas, receiving morning sun and afternoon shade:
- Sunlight: A minimum of 4-6 hours of sunlight is ideal.
- Shade: Protect from harsh afternoon sun, which can scorch the flowers.
Soil Requirements
The soil for bigleaf hydrangeas should be:
- Well-draining: Good drainage prevents root rot.
- Rich in organic matter: Loamy soil enriches growth.
- pH-neutral to slightly acidic: pH levels between 5.5-6.8 allow for optimal nutrient absorption.
Watering Needs
These hydrangeas require consistent moisture:
- Irrigation: Water them thoroughly at least once a week.
- Mulching: A layer of mulch around the base can help retain moisture and improve soil quality.
Care Tips for Reblooming Bigleaf Hydrangeas
- Pruning: Prune lightly in late winter or early spring before new growth begins. Removal of dead or weak stems will encourage lush blooms.
- Fertilizing: A balanced, slow-release fertilizer should be applied in early spring. This aids in robust flowering throughout the season.
- Winter Protection: In cold climates, adding mulch over the root zone can help protect roots from freezing temperatures.
- Pest Management: Watch for common pests such as aphids and spider mites. Use insecticidal soap if necessary.
Table: Common Issues and Solutions
| Issue | Solution |
|---|---|
| Wilting Leaves | Increase watering frequency and check for drainage. |
| Pest Infestation (e.g., aphids) | Use insecticidal soap or neem oil. |
| Lack of Blooms | Ensure proper pruning and sufficient sunlight. |
Understanding Flower Color
One of the magical features of bigleaf hydrangeas is their ability to change color based on soil pH:
- Acidic Soil (pH < 5.5): Blue flowers
- Neutral Soil (pH 6.0): Light purple flowers
- Alkaline Soil (pH > 7.0): Pink flowers
Gardeners can adjust soil pH with amendments to achieve the desired bloom color, adding an artistic touch to their landscaping.
