Hydrangeas are one of the most popular flowering shrubs for gardens. Known for their beautiful blooms, these plants are easy to grow and care for. But before you can enjoy the beauty of hydrangeas, you need to know how to plant them properly. In this article, we will guide you through the steps of planting a hydrangea outside.

Choose the Right Location

The first step in planting a hydrangea is to choose the right location. Hydrangeas need partial shade to thrive, so look for an area in your garden that gets morning sun and afternoon shade. Make sure the soil is well-draining and rich in organic matter. Avoid planting hydrangeas in areas with heavy clay or sandy soil.

Prepare the Soil

Before planting, prepare the soil by adding compost or well-rotted manure. This will help improve soil fertility and drainage. Mix the compost or manure into the top 6-8 inches of soil.

Choose the Right Hydrangea

Choosing the right hydrangea is important for a successful planting. There are many different varieties of hydrangeas, each with their own unique characteristics. Some hydrangeas bloom on old wood, while others bloom on new wood. Make sure you choose a variety that is suited to your climate and soil conditions.

Planting the Hydrangea

Once you have chosen the perfect hydrangea and location, it’s time to plant it. Dig a hole that is twice as wide as the root ball and just as deep. Gently remove the hydrangea from its container and loosen any tangled roots. Place the hydrangea in the hole and backfill with soil, making sure the top of the root ball is level with the soil surface.

Watering and Mulching

After planting, water the hydrangea thoroughly to help settle the soil around the roots. Mulch around the plant with a 2-3 inch layer of organic mulch, such as bark or leaves. Mulching helps retain moisture in the soil and suppress weeds.

Pruning Hydrangeas

Pruning hydrangeas is an important part of plant care. The timing and method of pruning depends on the variety of hydrangea. Some hydrangeas bloom on old wood, which means they should be pruned after flowering. Other hydrangeas bloom on new wood, which means they can be pruned in late winter or early spring before new growth appears.

Fertilizing Hydrangeas

Fertilizing hydrangeas can help promote healthy growth and flowering. Use a balanced fertilizer, such as 10-10-10, in early spring before new growth appears. Avoid fertilizing in late summer or fall, as this can encourage new growth that may not have time to harden off before winter.

Pest and Disease Control

Hydrangeas are generally disease and pest-resistant, but they can be susceptible to certain problems, such as powdery mildew or aphids. To prevent these issues, make sure your hydrangeas are planted in well-draining soil and have good air circulation. If you do notice pests or disease, treat them promptly with an appropriate insecticide or fungicide.


Planting a hydrangea outside is a great way to add beauty and color to your garden. By following these tips, you can ensure your hydrangea thrives and blooms for years to come. Remember to choose the right location, prepare the soil, choose the right hydrangea, and care for your plant with proper watering, mulching, pruning, fertilizing, and pest and disease control.
