Hydrangeas grace the landscape with beautiful flowers in the spring and summer. The most colorful hydrangeas are bigleaf hydrangeas, Hydrangea macrophylla. Their flowers are usually either pink or blue. Flower color depends on the pH of the soil, a measure of soil acidity. Soil pH can be raised by applying lime. Some hydrangeas will respond to a higher pH (between 6.0 and 6.5) with pink flower color. To lower pH, apply aluminum sulfate. A lower pH (between 5.0 and 5.0) often results in blue flower color. A soil test will determine the existing pH and you can change your soil with the appropriate amendment to get the resulting flower color you want. Continue reading
