You may have heard a bit about how you can change the color of your hydrangea flowers based on changing the acidity or alkalinity of the soil. Effectively this is very true. To that end, hydrangeas like both acid and alkaline soil.
Are hydrangeas acid loving plants?
Not necessarily however they will thrive just fine in acidic soil. It’s difficult to say that they absolutely love it but there are very flexible and easy to cultivate shrub which will grow just as well in highly acidic soil or highly alkaline soil.
Do hydrangeas like acid soil?
Many hydrangeas do like acid soil and in fact, with highly acidic soil you will get a specific color of blooms if you have planted varieties like mop heads and Lace caps.

Not every hydrangea naturally produces blue flowers or pink flowers. There are some hydrangeas which produce white flowers or cream-colored flowers and these will never change in color. However, the bigleaf hydrangeas like the mop heads and the lace caps have colorful flowers that range from pink hues all the way through blue hues even upwards of purple. The color of the flower is based upon the chemistry of the soil which means that alkaline soil produces pinker colored flowers while acidic soil produces blue-coloured flowers.

- 2nd Generation simplified 3 pad design for improved accuracy to easily optimize soil pH.
- Enough soil test strips for 100 soil pH tests - Since soil pH can vary in different areas it is important to take multiple soil pH tests around your property. Essential for lawn soil pH testing and adjustments.
- Optimize soil pH to plants specific needs to increase nutrient availability. Proper soil pH is an essential key needed to unlock nutrients in your soil and make them available to plants. Great for indoor and outdoor applications. Houseplants, flowers, herbs, potted plants, annuals, perennials, trees, shrubs, fruits, and vegetables benefit from proper pH levels.
- Includes detailed full color pH testing handbook with lime and sulfur application charts

Growing pink hydrangeas
If you want pink blooms you want to deprive the soil of aluminum by maintaining a highly alkaline soil with a pH level between 6.0 and 6.2. To achieve this you can apply high phosphorus fertilizers and that will stop your hydrangea or at the very least inhibit it from absorbing the aluminum. If you want to do it naturally and much more slowly you can apply garden lime regularly.
