The Science of Hydrangea Color

The color of hydrangea flowers is determined by the acidity of the soil. In alkaline soil, hydrangeas will bloom pink or red. In acidic soil, they will bloom blue or purple. This is because the aluminum in the soil is more soluble in acidic conditions, and it is the aluminum that gives hydrangeas their blue color.

The pH of your soil can be tested with a pH meter or pH test kit. The ideal pH for growing blue hydrangeas is between 5.2 and 5.5. If your soil is too alkaline, you can lower the pH by adding sulfur or aluminum sulfate.

Choosing the Right Soil and Fertilizer

In addition to pH, the type of soil you use can also affect the color of your hydrangeas. Hydrangeas prefer well-drained, loamy soil that is rich in organic matter. If your soil is sandy or clayey, you may need to add compost or peat moss to improve drainage and add organic matter.

You should also fertilize your hydrangeas regularly. A balanced fertilizer, such as 10-10-10, is a good choice. You can fertilize your hydrangeas in the spring and fall.

Watering and Care

Hydrangeas need regular watering, especially during the summer months. Water your hydrangeas deeply, so that the water reaches the roots. You should also mulch around your hydrangeas to help retain moisture.

Hydrangeas are relatively pest- and disease-resistant, but they can be susceptible to scale, aphids, and powdery mildew. If you notice any pests or diseases on your hydrangeas, treat them immediately with an appropriate pesticide or fungicide.

Protecting Your Hydrangeas

In cold climates, hydrangeas may need to be protected from the cold. You can do this by covering your hydrangeas with a burlap sack or frost cloth. You should also water your hydrangeas well before the first frost to help them survive the winter.

FAQ of blue purple hydrangea

Q: What makes a blue hydrangea?

A: Blue hydrangeas bloom in acidic soils, usually with a pH of 5.5 or less. The acidity of the soil affects the way that the hydrangeas take up aluminum, which is what gives them their blue color. In alkaline soils, the aluminum is not as available to the hydrangeas, so they will bloom in shades of pink or purple.

Q: How do I keep hydrangeas purple blue?

A: There are a few things you can do to keep hydrangeas purple blue. First, make sure that the soil is acidic. You can test the pH of your soil with a pH test kit. If the soil is alkaline, you can add sulfur to acidify it.

Second, water your hydrangeas with rainwater or distilled water. Tap water can contain alkaline minerals that can make the hydrangeas bloom in shades of pink or purple.

Finally, you can add aluminum sulfate to the soil around your hydrangeas. This will help to ensure that the hydrangeas have enough aluminum to bloom blue.
