Choosing the Right Soil

The pH of your soil is one of the most important factors in determining the color of your hydrangeas. In alkaline soil, hydrangeas will bloom pink. In acidic soil, they will bloom blue.

The ideal pH for blue hydrangeas is between 5.2 and 5.5. If your soil is more alkaline than this, you can add aluminum sulfate to lower the pH. Aluminum sulfate is a naturally occurring mineral that can be found at most garden centers.

To add aluminum sulfate to your soil, simply mix 1/4 ounce of aluminum sulfate with 1 gallon of water. Pour the solution around the base of your hydrangeas, and water it in well.

You can also test the pH of your soil with a soil test kit. Soil test kits are available at most garden centers.

Planting Blue Hydrangeas

Once you've got your soil acidic, you're ready to plant your blue hydrangeas. Blue hydrangeas prefer full sun, but they will tolerate some shade. They also need well-drained soil.

When planting your blue hydrangeas, dig a hole that is twice as wide and as deep as the root ball. Place the hydrangea in the hole, and backfill with soil. Water the hydrangea well, and mulch around the base.

Caring for 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 in the spring with a fertilizer that is high in phosphorus.

To deadhead your hydrangeas, simply remove the spent blooms. This will encourage new blooms to form.
