Hydrangea in Pots Outdoors: An Overview

Growing hydrangea in pots outdoors is a great way to add color and beauty to your outdoor space. With their large, showy blooms and easy-to-care-for nature, hydrangeas make an excellent choice for container gardening. In this guide, we'll take a closer look at how to grow hydrangea in pots outdoors, including everything from selecting the right container to caring for your plants.

Choosing the Right Container

The first step to growing hydrangea in pots outdoors is to choose the right container. You'll want to select a container that is large enough to accommodate the size of your plant, as well as provide adequate drainage. Some popular container materials include terra cotta, plastic, and ceramic.

Terra Cotta Containers

Terra cotta containers are a popular choice for growing hydrangea in pots outdoors because they are porous and allow air to circulate around the roots. This helps to prevent root rot, which can be a problem in containers that don't have good drainage. Keep in mind that terra cotta containers can dry out quickly, so you'll need to water your plants more frequently.

Plastic Containers

Plastic containers are lightweight and affordable, making them a popular choice for container gardening. They are also available in a wide range of sizes and colors, so you can easily find one that fits your style. However, plastic containers don't breathe like terra cotta or ceramic, which can lead to moisture buildup and root rot.

Ceramic Containers

Ceramic containers are a beautiful and durable choice for growing hydrangea in pots outdoors. They come in a variety of colors and styles, and are less likely to crack or break than terra cotta. However, they can be heavy and difficult to move, which can be a drawback if you need to bring your plants indoors during the winter months.

Selecting the Right Soil Mix

In addition to choosing the right container, you'll also need to select the right soil mix for your hydrangea in pots outdoors. Hydrangeas prefer soil that is rich in organic matter and has good drainage. Here are some tips for selecting the right soil mix:

Use a High-Quality Potting Soil

Choose a potting soil that is specifically designed for container gardening. Look for a soil that contains peat moss, perlite, or vermiculite, which will help to improve drainage and retain moisture.

Add Compost or Organic Matter

Mix in some compost or other organic matter to enrich the soil and provide nutrients for your plants. You can also add a slow-release fertilizer to promote healthy growth.

Avoid Garden Soil

Avoid using garden soil in your containers, as it can be too heavy and dense for container gardening. It can also contain weed seeds and other pests that can harm your plants.

Positioning Your Container

Once you've selected the right container and soil mix, it's time to position your container in the right location. Hydrangeas prefer partial shade, so look for a spot in your outdoor space that receives morning sun and afternoon shade.

Avoid Full Sun

Avoid placing your container in full sun, as this can cause your plants to wilt and dry out quickly. If you live in a hot climate, you may need to move your container to a shadier spot during the hottest part of the day.

Provide Adequate Airflow

Make sure your container is positioned in an area that has good airflow. This will help to prevent moisture buildup and reduce the risk of fungal diseases.

Watering Your Hydrangea in Pots Outdoors

One of the most important aspects of caring for your hydrangea in pots outdoors is watering. Hydrangeas prefer moist soil, but they don't like to be sitting in water. Here are some tips for watering your plants:

Water Frequently

Hydrangeas in containers will need to be watered more frequently than those planted in the ground. Check the soil daily and water when the top inch of soil feels dry.

Avoid Overwatering

Avoid overwatering your plants, as this can lead to root rot and other problems. Make sure your container has good drainage and avoid letting water sit in the saucer.

Avoid Underwatering

Underwatering can also be a problem, especially during hot weather. Make sure your plants are getting enough water by checking the soil regularly and adjusting your watering schedule as needed.

Pruning and Fertilizing Your Hydrangea in Pots Outdoors

In addition to watering, you'll also need to prune and fertilize your hydrangea in pots outdoors to keep it healthy and thriving.

Pruning

Prune your plants in late winter or early spring before new growth appears. Remove any dead or damaged branches, as well as any branches that are crossing or rubbing against each other. You can also prune your plants to control their size and shape.

Fertilizing

Fertilize your plants in early spring and again in mid-summer with a slow-release fertilizer. Follow the instructions on the package for application rates.

Pests and Diseases

Like all plants, hydrangeas in pots outdoors can be susceptible to pests and diseases. Here are some common problems to watch out for:

Aphids

Aphids are small insects that feed on the sap of plants. They can be controlled with insecticidal soap or neem oil.

Spider Mites

Spider mites are tiny pests that can cause damage to the leaves of your plants. They can be controlled with insecticidal soap or by spraying your plants with a strong jet of water.

Fungal Diseases

Fungal diseases like powdery mildew and botrytis can be a problem for hydrangeas in pots outdoors. To prevent these diseases, make sure your plants have good airflow and avoid getting water on the leaves.

Growing hydrangea in pots outdoors is a wonderful way to add beauty and color to your outdoor space. By selecting the right container, soil mix, and location, as well as providing proper care and maintenance, you can enjoy these stunning plants year after year.
