How to Space and Plant Hydrangea in a Pot

Hydrangeas are a popular flowering shrub that can add color and beauty to any garden or patio. One way to enjoy these lovely plants is to grow them in pots. In this article, we will discuss how to space and plant hydrangea in a pot.

Choose the Right Container

When choosing a container for your hydrangea, it's important to consider the size and growth habits of the plant. Hydrangeas can grow quite large, so it's best to select a container that is at least 18 inches in diameter and 18 inches deep. This will allow enough room for the roots to grow and the plant to thrive.

Make sure the container has drainage holes to prevent water from collecting at the bottom and causing root rot. Also, consider the weight of the container when it's filled with soil and water. You may want to choose a lightweight container if you plan on moving the plant around frequently.

Prepare the Soil

The soil you use for your hydrangea should be rich and well-draining. You can use a pre-mixed potting soil or create your own by mixing equal parts of peat moss, perlite, and compost. Fill the container with enough soil to reach about 2 inches below the rim.

Hydrangeas prefer slightly acidic soil with a pH between 5.5 and 6.5. You can test the pH of your soil with a soil test kit, which can be purchased at most garden centers. If your soil is too alkaline, you can lower the pH by adding sulfur or aluminum sulfate.

Plant the Hydrangea

Before planting the hydrangea, water it thoroughly to help loosen the roots and make it easier to remove from the nursery container. Carefully remove the plant from the nursery container and gently loosen any tangled roots. Place the hydrangea in the center of the pot, making sure to keep the top of the root ball level with the soil surface.

Fill in around the sides of the root ball with additional soil, gently pressing down to eliminate any air pockets. Water the plant again to help settle the soil and encourage root growth.

Space Multiple Hydrangeas

If you want to plant more than one hydrangea in a pot, make sure to space them properly. A good rule of thumb is to plant one hydrangea per 18-inch diameter of the container. For example, if you have a 36-inch container, you can plant two hydrangeas.

Make sure to space the hydrangeas evenly around the pot, leaving a few inches between each plant. This will give them enough room to grow without competing for resources.

Care for Your Hydrangea

Hydrangeas in pots require regular care to thrive. Make sure to water them regularly, keeping the soil consistently moist but not waterlogged. Hydrangeas are thirsty plants and may require daily watering during hot weather.

Feed your hydrangeas once a month with a balanced, slow-release fertilizer formulated for acid-loving plants. This will provide the necessary nutrients for healthy growth and flowering.

Prune your hydrangeas in late winter or early spring to remove any dead or damaged branches and promote healthy growth. You can also prune for shape and size, cutting back any leggy or overgrown branches.

With these tips, you can create a beautiful and thriving hydrangea garden in pots. Enjoy the lovely blooms and lush foliage of these beloved plants right on your deck or patio.
