Did You Know?
1. Despite popular belief, hydrangeas are not always perennials. While some species, such as the common garden hydrangea (Hydrangea macrophylla), are indeed perennials, others, like the oakleaf hydrangea (Hydrangea quercifolia), are deciduous and lose their leaves each year.
2. Hydrangeas have the fascinating ability to change color based on the pH level of the soil they are planted in. In acidic soil (pH less than 7), the flowers tend to appear blue, while in alkaline soil (pH greater than 7), they lean towards pink.
3. The color of the hydrangea’s flowers can also be influenced by the presence of aluminum ions in the soil. When aluminum ions are present, they react with the pigments in the flowers, causing them to turn blue. If the soil lacks aluminum, the flowers will typically appear pink.
4. One interesting fact about hydrangeas is that their name derives from the Greek words “hydor,” meaning water, and “angeion,” meaning vessel. This name alludes to the hydrangea’s need for a generous amount of water to thrive.
5. While hydrangeas are commonly associated with Japan, they actually have their origins in East Asia, specifically in China, Korea, and Japan. The first hydrangea species brought to Europe was the Hydrangea macrophylla, which arrived from Japan in the early 18th century.

Growing And Pruning Hydrangeas: Tips For A Healthy Plant
To ensure that hydrangeas grow and flower to their fullest potential, it is important to provide them with the proper care. Fertilizing with a bloom-promoting fertilizer in the spring is recommended, as it helps to promote healthy growth and abundant flower production. Flower color is influenced by the pH of the soil, with acid soils producing blue flowers and alkaline soils producing pink flowers. Adjusting the soil pH can be done by adding amendments or using specific fertilizers designed to produce the desired flower color.
Pruning hydrangeas is essential for their overall health and appearance. It is best to prune in late winter or early spring before new growth begins to emerge. Dead wood should be removed, as well as any thin or weak stems. Hydrangeas can grow quite large, so it is important to provide enough space for them to spread out. Regular pruning promotes strong and healthy growth, as well as encourages the plant to flower more prolifically.
Mulching is another important aspect of hydrangea care. After the soil has warmed in the spring, a layer of mulch should be spread around the base of the plant. This helps to retain moisture and suppress weed growth. Additionally, it is important to remove and destroy any infected foliage to prevent the spread of diseases. Covering the stems of the hydrangea with mulch can also provide some protection against winter cold temperatures and wind.
Flower Colors And Soil pH: The Hydrangea Connection
The color of hydrangea flowers is directly influenced by the pH level of the soil they are planted in. Acidic soils, with a pH below 7, tend to produce blue flowers, while alkaline soils, with a pH above 7, tend to produce pink flowers. White hydrangeas are not influenced by soil pH and will remain white regardless. To achieve the desired flower color, it is necessary to adjust the soil pH accordingly.
Hydrangeas planted in acidic soil can be maintained in their blue color by adding aluminum sulfate or sulfur to the soil. These amendments help to lower the pH and make the soil more acidic. For those wanting pink flowers, adding lime or other alkaline amendments can raise the soil pH. It is important to use these amendments judiciously and follow package instructions to avoid over-adjusting the pH, which can harm the plant.
It is worth noting that some hydrangea varieties, such as the ‘Endless Summer’ series, are known as “color-changing hydrangeas” because their flower color can vary depending on the soil pH and the availability of aluminum in the soil. This provides gardeners with the opportunity to enjoy a range of colors on a single plant.
- Acidic soils (pH below 7) produce blue flowers
- Alkaline soils (pH above 7) produce pink flowers
- White hydrangeas are not affected by soil pH
- Add aluminum sulfate or sulfur for blue flowers
- Add lime or alkaline amendments for pink flowers
Protecting Hydrangeas In Winter: Strategies And Techniques
In areas with harsh winter conditions, protecting hydrangeas is essential for their survival. This can be achieved through several strategies and techniques. One effective method is to wrap the plants in burlap to protect them from cold temperatures and wind. Wrapping the stems and covering the entire plant with burlap helps to create a layer of insulation that shields the hydrangeas from harsh weather conditions.
Container-grown hydrangeas also require special winter care. It is important to choose winter-hardy varieties when growing hydrangeas in northern zones. These varieties are better equipped to withstand freezing temperatures. In addition to selecting the right plant, providing adequate insulation for the container is crucial. Wrapping the container with bubble wrap or placing it in a protected area, such as a garage or shed, can help protect the plant’s roots from freezing.
In both garden beds and containers, strong root development is important for winter survival. Therefore, it is recommended to water hydrangeas deeply before the ground freezes to ensure that they have sufficient moisture for their dormant period. Applying a layer of mulch around the base of the plant after the ground has frozen can also help insulate the roots and protect them from fluctuating temperatures.
