In this ultimate guide, we'll explore everything you need to know about growing and caring for early blue hydrangeas, including planting tips, proper care, and how to maintain their beautiful blue color.

Early Blue Hydrangea: An Overview

Planting Early Blue Hydrangeas

Planting Early Blue Hydrangeas

  1. Choose a location with partial shade and well-draining soil. Early blue hydrangeas prefer morning sun and afternoon shade to protect them from the harsh midday sun.
  2. Dig a hole twice as wide and just as deep as the root ball.
  3. Amend the soil with organic matter, such as compost, to improve drainage and add nutrients.
  4. Place the hydrangea in the hole, making sure the top of the root ball is level with the soil surface.
  5. Fill in the hole with soil, gently patting it down to eliminate air pockets.
  6. Water the plant thoroughly to settle the soil around the roots.

Caring for Early Blue Hydrangeas

Caring for Early Blue Hydrangeas

  • Watering: Keep the soil consistently moist but not waterlogged. Early blue hydrangeas are sensitive to drought, so make sure to water them during dry spells.
  • Fertilizing: Apply a slow-release, balanced fertilizer in spring and again in midsummer. Avoid using fertilizers high in phosphorus, which can interfere with the plant's ability to absorb aluminum (necessary for the blue color).
  • Pruning: Prune early blue hydrangeas in late winter or early spring, removing any dead or damaged branches. This variety blooms on old wood, so avoid cutting back any healthy stems.
  • Mulching: Apply a layer of mulch around the base of the plant to help retain moisture and regulate soil temperature.

Maintaining the Blue Color

Maintaining Blue Color

The intensity of the blue color in early blue hydrangeas is determined by the soil's pH and the availability of aluminum. To maintain the blue color, follow these steps:

  1. Test the soil pH. Blue hydrangeas require slightly acidic soil (pH 5.5-6.5). If the soil is too alkaline, add sulfur or aluminum sulfate to lower the pH.
  2. Ensure aluminum is available in the soil. Add aluminum sulfate to the soil according to the manufacturer's instructions.
  3. Avoid using phosphorus-rich fertilizers, as they can interfere with the plant's ability to absorb aluminum.
  4. Keep the soil consistently moist, as dry soil can reduce the availability of aluminum.

Frequently Asked Questions

Q: Can I grow early blue hydrangeas in containers?

A: Yes, early blue hydrangeas can be grown in containers. Choose a large pot with drainage holes and use well-draining, slightly acidic potting mix. Make sure to water the plant regularly, as container-grown plants tend to dry out faster than those in the ground.

Q: How can I change the color of my early blue hydrangea?

A: The color of hydrangea flowers is influenced by the soil pH and the availability of aluminum. To change the color from blue to pink, raise the soil pH by adding lime. To change from pink to blue, lower the soil pH by adding sulfur or aluminum sulfate.

Q: Why are the leaves on my early blue hydrangea turning yellow?

A: Yellow leaves can be a sign of several issues, including overwatering, underwatering, or nutrient deficiencies. Check the soil moisture and adjust your watering schedule accordingly. If the problem persists, test the soil pH and nutrient levels and amend as needed.

Q: When is the best time to transplant early blue hydrangeas?

A: The best time to transplant early blue hydrangeas is in late winter or early spring, before the plant starts to produce new growth. This allows the plant to establish its root system before the growing season begins.
