Choosing the Right Variety

There are many different varieties of blue hydrangeas available, so it's important to choose one that is suited to your climate and growing conditions.

Some popular varieties of blue hydrangeas include:

• Bigleaf hydrangea (Hydrangea macrophylla): This is the most common type of blue hydrangea. It produces large, showy flowers that can reach up to 12 inches in diameter. Bigleaf hydrangeas are hardy to USDA zones 5-9.
• Smooth hydrangea (Hydrangea arborescens): This type of hydrangea is smaller than bigleaf hydrangeas, but it is just as beautiful. It produces clusters of white, pink, or blue flowers that bloom in the summer. Smooth hydrangeas are hardy to USDA zones 3-8.
• Mophead hydrangea (Hydrangea paniculata): This type of hydrangea produces large, rounded flower clusters that can reach up to 18 inches in diameter. Mophead hydrangeas are white, pink, or blue. They are hardy to USDA zones 3-8.

Planting Your Blue Hydrangeas

Once you've chosen the right variety of blue hydrangea, it's time to plant your plants. Blue hydrangeas prefer full sun to partial shade. They also prefer moist, well-drained soil.

When planting your blue hydrangeas, dig a hole that is twice as wide and deep as the root ball. Amend the soil with compost or peat moss to improve drainage and add organic matter. Place the hydrangea in the hole and backfill with soil, tamping down gently to remove any air pockets. Water the hydrangea thoroughly.

Caring for Your Blue Hydrangeas

Blue hydrangeas are relatively easy to care for. They need regular watering, especially during hot, dry weather. You should also fertilize your hydrangeas once a year in the spring with a balanced fertilizer.

In the fall, you can prune your blue hydrangeas to remove dead or damaged branches. You can also prune them to shape the plant or to control its size.

Changing the Color of Your Blue Hydrangeas

The color of blue hydrangeas is affected by the pH of the soil. In acidic soil (pH of 5.5 or lower), blue hydrangeas will produce blue flowers. In alkaline soil (pH of 7.5 or higher), blue hydrangeas will produce pink flowers.

If you want to change the color of your blue hydrangeas, you can adjust the pH of the soil. To make the soil more acidic, add sulfur or peat moss to the soil. To make the soil more alkaline, add ground limestone or wood ash to the soil.

It may take several weeks or months for the pH of the soil to change and for the flowers on your hydrangeas to change color.
