Collection: Bigleaf Hydrangeas

Bigleaf hydrangea, scientifically known as Hydrangea macrophylla, is a deciduous shrub that is widely admired for its large, showy flower heads and attractive foliage. It is one of the most popular and commonly grown hydrangea species. The common name "bigleaf" refers to the plant's large, broad leaves.

Key features of bigleaf hydrangea include:

1. Flower Heads: Bigleaf hydrangeas produce large, globe-shaped flower clusters that can vary in color depending on the soil pH. The flowers can range from pink to blue or purple. The color change is influenced by the presence of aluminum in the soil.

2. Leaf Size: As the name suggests, bigleaf hydrangea has large, coarse-textured leaves that contribute to its overall lush appearance. The leaves are often heart-shaped and provide an attractive backdrop to the colorful blooms.

3. Varieties: There are different varieties and cultivars of bigleaf hydrangea, each with its own unique characteristics. Some cultivars are prized for their ability to produce blue or pink flowers, while others may have unique leaf shapes or growth habits.

4. Growing Conditions: Bigleaf hydrangeas prefer well-drained soil and partial shade. They can be sensitive to harsh sunlight and may benefit from protection during the hottest parts of the day. The soil pH influences the flower color, with acidic soils promoting blue flowers and alkaline soils promoting pink flowers.

5. Pruning: Pruning requirements may vary based on the specific variety, but in general, bigleaf hydrangeas can be pruned after flowering. Removing spent blooms and dead wood can help maintain a tidy appearance.

Popular cultivars of bigleaf hydrangea include 'Nikko Blue,' 'Endless Summer,' and 'Forever Pink,' among others.

These hydrangeas are often used in gardens, landscapes, and as potted plants, adding a touch of elegance and color to outdoor spaces. Understanding the specific care needs, including soil conditions and pruning, can help ensure the successful cultivation of bigleaf hydrangeas in your garden.

Pruning bigleaf hydrangeas (Hydrangea macrophylla) is an important part of their care routine. Here are guidelines on when to prune and how to care for bigleaf hydrangeas:

When to prune Bigleaf Hydrangea:

1. Timing: Bigleaf hydrangeas should be pruned after they have finished flowering. The best time is typically in late summer or early fall. Pruning at this time allows the plant to set buds for the next season during the fall.

2. Removing Spent Blooms: After the hydrangea has finished flowering, you can deadhead or remove spent blooms. Cut the flower stems just below the faded flower head. This not only tidies up the plant but can also encourage the development of new buds.

3. Selective Pruning: If the plant needs shaping or if there are dead or weak stems, you can selectively prune them. However, avoid extensive pruning in late fall or winter as this can remove potential flower buds for the next season.

Bigleaf Hydrangea Care:

1. Soil Conditions: Bigleaf hydrangeas prefer well-drained soil that is rich in organic matter. They thrive in slightly acidic to slightly alkaline soil. To influence flower color, consider the soil pH—acidic soils tend to produce blue flowers, while alkaline soils result in pink flowers.

2. Watering: Keep the soil consistently moist, especially during hot or dry periods. However, avoid waterlogged conditions, as this can lead to root rot.

3. Sunlight: Bigleaf hydrangeas prefer partial shade, especially in the afternoon. Protect them from harsh sunlight, as too much sun can lead to leaf burn and reduce flower production.

4. Mulching: Apply a layer of mulch around the base of the plant to help retain soil moisture and regulate temperature. Mulching also helps suppress weeds.

5. Fertilizing: Fertilize bigleaf hydrangeas in spring with a balanced fertilizer. Avoid high-phosphorus fertilizers, as they can hinder the uptake of aluminum, affecting flower color.

6. Winter Protection: In colder climates, provide winter protection by mulching around the base of the plant to insulate the roots from extreme cold.

Remember that individual varieties of bigleaf hydrangea may have specific care requirements, so it's always a good idea to check for any cultivar-specific recommendations. Overall, proper pruning and care contribute to healthy growth and abundant blooms in bigleaf hydrangeas.
