Blue Wave Hydrangea Care & Growing Tips

Caring for Blue Wave Hydrangeas

To ensure the health and vitality of your Blue Wave Hydrangea, consider the following care tips:

  1. Sunlight: You may be wondering, “Do blue hydrangeas like full sun?” But like many varieties, Blue Wave Hydrangeas thrive in partial shade to filtered sunlight. While they can tolerate some morning sun, excessive exposure to hot afternoon sun may lead to wilting.
  2. Soil: Provide well-draining soil rich in organic matter. Maintaining the soil pH in the acidic to neutral range (around 5.5 to 6.5) will enhance the intensity of the blue blooms. If you’re wondering, “Where is the best place to plant blue hydrangeas?” then this is an important piece of information to keep in mind.
  3. Watering: Keep the soil consistently moist, especially during dry periods. Hydrangeas are relatively thirsty plants and benefit from regular watering.
  4. Pruning: Prune your Blue Wave Hydrangea in late winter or early spring to remove dead or weak stems. This encourages new growth and ensures a more compact and robust plant.
  5. Mulching: Apply a layer of organic mulch around the base of the plant to help retain moisture, regulate soil temperature, and suppress weeds.
