How to take care of your hydrangea ?

Hydrangeas are elegant flowering plants that have captivated gardeners and flower enthusiasts for centuries. Native to Asia and the Americas, these enchanting blooms have a rich history and are beloved for their large, showy flower heads that come in an array of captivating colors. In this article, we will delve into the origins and history of the hydrangea plant before exploring essential tips and advice on how to care for these stunning flowers.

Origins and History:

Hydrangeas belong to the Hydrangeaceae family and encompass a diverse range of species, including Hydrangea macrophylla, Hydrangea paniculata, and Hydrangea arborescens, among others. The name “hydrangea” is derived from the Greek words “hydor” and “angeion,” which translate to “water vessel,” alluding to the plant’s preference for ample moisture.

The first hydrangea species were discovered in Japan, where they hold great cultural significance. In Japanese tradition, hydrangeas symbolize gratitude, heartfelt emotions, and deep understanding. The flowers are often used in festivals and ceremonies, adding a touch of grace and elegance to the surroundings.

Taking Care of Hydrangeas:

  1. Light Requirements: Hydrangeas generally prefer partial shade, especially during the hottest hours of the day. Morning sun with afternoon shade is ideal for most varieties. In hotter regions, hydrangeas benefit from dappled shade or protection from intense afternoon sunlight.
  2. Soil and Moisture: Well-draining, fertile soil is crucial for healthy hydrangea growth. Prepare the soil by incorporating organic matter such as compost or aged manure. Hydrangeas also require consistent moisture, so watering deeply once or twice a week is recommended. However, avoid overwatering, as it may lead to root rot.
  3. Pruning: Pruning hydrangeas helps maintain their shape, encourages new growth, and enhances overall plant health. The timing and method of pruning depend on the hydrangea variety. For Hydrangea macrophylla, prune immediately after flowering by removing spent blossoms and thinning out weak or damaged stems. Hydrangea paniculata blooms on new wood, so prune in late winter or early spring before new growth appears.
  4. Fertilization: Applying a balanced slow-release fertilizer in spring can promote healthy growth and abundant blooms. Choose a fertilizer with a higher phosphorus content to encourage flower production. Follow the package instructions for proper application rates.
  5. Changing Flower Colors: Certain hydrangea varieties, such as Hydrangea macrophylla, can produce different flower colors depending on the soil pH. Acidic soil (pH below 7) results in blue flowers, while alkaline soil (pH above 7) produces pink flowers. Adjusting the soil pH can help achieve the desired color. For blue blooms, add aluminum sulfate or sulfur to acidify the soil, and for pink blooms, add lime to make the soil more alkaline.


Hydrangeas are exquisite plants that add beauty and elegance to any garden or landscape. By providing the right growing conditions and following proper care techniques, you can enjoy the magnificent blooms of hydrangeas year after year. Remember to consider their light requirements, moisture needs, pruning practices, and even the soil pH for desired flower colors.
