Understanding Hydrangea Varieties

- Lacecap Hydrangeas (Hydrangea macrophylla): Feature flattened flower heads with tiny fertile flowers in the center and larger, showier flowers around the edges.
- Panicle Hydrangeas (Hydrangea paniculata): Distinguished by their cone-shaped flower clusters that typically start white and may turn pink or red as they age.

Cultivating Hydrangeas: Essential Care Tips
Providing the right care is crucial for healthy hydrangea growth and abundant blooms. Here’s a breakdown of essential care tips to help you cultivate thriving hydrangeas in your garden.
Light and Soil Requirements
Hydrangeas generally prefer morning sun and afternoon shade, especially in hotter climates. The ideal soil is well-draining, fertile, and slightly acidic.
| Factor | Requirement | Explanation |
|---|---|---|
| Sunlight | Morning sun, afternoon shade | Prevents leaf scorch and promotes optimal flower development. |
| Soil | Well-draining, fertile, slightly acidic | Ensures proper root growth and nutrient uptake. |
| Watering | Regular watering, especially during dry periods | Keeps the soil consistently moist, but not waterlogged. |
Pruning Hydrangeas: A Guide to Shaping and Blooming
Pruning hydrangeas correctly is essential for maintaining their shape and promoting abundant flowering. The pruning method varies depending on the hydrangea variety.
Important Pruning Fact: Mophead and lacecap hydrangeas bloom on old wood (growth from the previous year), so prune them sparingly, only removing dead or damaged branches after flowering. Panicle and smooth hydrangeas bloom on new wood (growth from the current year) and can be pruned more heavily in late winter or early spring.
