Hydrangeas are beloved garden plants known for their large, showy flower heads that come in a range of vibrant colors. Planting hydrangeas can be a rewarding experience, but it requires careful preparation and attention to detail. This comprehensive guide will provide you with step-by-step instructions on how to plant hydrangea bushes successfully, ensuring a thriving and beautiful addition to your garden.
Choosing the Right Hydrangea Variety
The first step in planting hydrangeas is to choose the right variety for your climate and desired flower color. There are several popular hydrangea species, including:
- Bigleaf Hydrangea (Hydrangea macrophylla): Known for its large, mophead or lacecap flowers in shades of blue, pink, purple, or white.
- Panicle Hydrangea (Hydrangea paniculata): Produces large, cone-shaped flower panicles in white that turn pink or red as they age.
- Smooth Hydrangea (Hydrangea arborescens): Features large, flat-topped flower clusters in white or cream.
- Oakleaf Hydrangea (Hydrangea quercifolia): Has unique oak-shaped leaves and produces white flower panicles.
Selecting the Planting Site
Hydrangeas prefer well-drained, acidic soil with a pH between 5.5 and 6.5. Choose a planting site that receives morning sun and afternoon shade. Avoid areas with strong winds or excessive heat.
Preparing the Soil
Before planting, amend the soil with organic matter such as compost or peat moss to improve drainage and fertility. Dig a hole that is twice as wide as the root ball and just as deep.
Planting the Hydrangea Bush
1. Remove the Hydrangea from the Container: Carefully remove the hydrangea from its container and gently loosen any circling roots.
2. Place the Hydrangea in the Hole: Position the hydrangea in the center of the hole and backfill with soil, tamping down gently to remove any air pockets.
3. Water Thoroughly: Water the hydrangea deeply to settle the soil around the roots.
4. Mulch Around the Base: Spread a layer of organic mulch, such as shredded bark or compost, around the base of the hydrangea to retain moisture and suppress weeds.
Watering and Fertilizing
Hydrangeas require regular watering, especially during hot, dry weather. Water deeply at the base of the plant, avoiding overhead watering. Fertilize hydrangeas monthly during the growing season with a balanced fertilizer.
Pruning Hydrangeas
Pruning hydrangeas is essential to maintain their shape and encourage flowering. The pruning method depends on the hydrangea variety:
- Bigleaf Hydrangea: Prune in late winter or early spring, removing old or damaged canes.
- Panicle Hydrangea: Prune in late winter or early spring, cutting back branches to two to three buds from the base.
- Smooth Hydrangea: Prune in late winter or early spring, cutting back stems to the ground.
- Oakleaf Hydrangea: Prune in late winter or early spring, removing any suckers or dead branches.
Controlling Pests and Diseases
Hydrangeas are generally disease-resistant, but they can be susceptible to pests such as aphids, spider mites, and Japanese beetles. Use insecticidal soap or neem oil to control pests. Fungal diseases can be prevented by providing good air circulation and avoiding overwatering.
Troubleshooting Common Problems
- Yellowing Leaves: Iron deficiency due to high soil pH. Amend the soil with iron sulfate.
- Wilting Leaves: Lack of water. Increase watering frequency and check soil moisture.
- No Flowers: Insufficient sunlight or improper pruning. Ensure the hydrangea receives enough morning sun and prune correctly according to the variety.
- Blue Flowers Turning Pink: High soil pH. Add sulfur or aluminum sulfate to lower the soil pH.
Key Points: A Thriving Hydrangea Haven
By following these detailed instructions, you can successfully plant and care for hydrangeas, creating a vibrant and beautiful addition to your garden. With proper care and attention, your hydrangeas will flourish and reward you with stunning blooms for years to come.

Q: Why are my hydrangea leaves turning yellow?
A: Yellowing leaves can indicate iron deficiency due to high soil pH. Amend the soil with iron sulfate to correct the pH balance.
Q: How do I change the color of my hydrangeas?
A: The flower color of bigleaf hydrangeas can be influenced by soil pH. Adding aluminum sulfate will turn the flowers blue, while adding lime will turn them pink.
Q: Can I grow hydrangeas in containers?
A: Yes, hydrangeas can be grown in containers, but they will require more frequent watering and fertilization. Choose a pot with drainage holes and use a well-draining potting mix.
