Hydrangeas are beloved for their captivating blooms, and they have the remarkable ability to change color based on the soil’s pH level. To achieve the coveted blue hue, follow these simple steps:
1. Test your soil’s pH level: Determine if your soil is acidic enough for blue hydrangeas. A pH of 5.5 or lower is ideal.
2. Choose a soil amendment: Aluminum sulfate is a common choice to increase soil acidity. Mix a quarter-ounce per gallon of water.
3. Apply the amendment: Soak the soil around your hydrangeas with the aluminum sulfate solution. Reapply monthly until the desired color is achieved.
4. Maintain soil acidity: Fertilize with acidic compost or organic matter to sustain the low pH level. Examples include orange peels, coffee grounds, and peat moss.
Remember, patience is key, as the color change may take some time. With these expert tips and consistent care, you’ll be rewarded with stunning blue hydrangeas that will undoubtedly be the envy of your garden.
