Hydrangeas are beautiful flowering plants that can add a touch of elegance to any home. These plants are known for their large, colorful blooms that can last for several weeks. While hydrangeas are typically grown outdoors, they can also be grown indoors with a little bit of effort and care. In this article, we will share some tips and techniques for growing hydrangeas indoors.

Choosing the Right Hydrangeas

The first step to growing hydrangeas indoors is to choose the right variety. Some of the best hydrangeas for indoor growing include the Bigleaf Hydrangea (Hydrangea macrophylla), the Mountain Hydrangea (Hydrangea serrata), and the Oakleaf Hydrangea (Hydrangea quercifolia). These varieties are well-suited for indoor growing as they do not require a lot of space and can thrive in containers.

Preparing the Soil

Once you have chosen your hydrangea variety, the next step is to prepare the soil. Hydrangeas prefer moist, well-draining soil with a slightly acidic pH. You can create this type of soil by mixing equal parts of peat moss, perlite, and potting soil. Make sure the soil is moist but not waterlogged before planting your hydrangea.

Planting Your Hydrangea

When planting your hydrangea, choose a container that is at least 12 inches in diameter and has drainage holes. Fill the container with your prepared soil and make a hole in the center. Gently remove your hydrangea from its nursery pot and place it in the hole. Fill in the remaining space with soil and water thoroughly. Place your container in a location with bright, indirect light.

Caring for Your Hydrangea

Hydrangeas require regular care to thrive indoors. Keep the soil moist but not waterlogged, and fertilize your hydrangea every two weeks with a balanced fertilizer. Prune your hydrangea regularly to promote new growth and remove any dead or damaged leaves. It is also important to monitor your plant for pests and diseases, such as spider mites and powdery mildew.

Controlling the Temperature and Humidity

Hydrangeas prefer a cool, humid environment. Keep your indoor temperature between 60-70 degrees Fahrenheit and avoid placing your plant near any heat sources or air conditioning units. You can also increase the humidity around your plant by placing a tray of water nearby or using a humidifier.

Encouraging Blooms

One of the most rewarding aspects of growing hydrangeas indoors is seeing them bloom. To encourage blooms, make sure your plant is getting enough light and fertilize it with a phosphorus-rich fertilizer in the spring. You can also promote blooms by manipulating the soil pH. Adding aluminum sulfate to your soil can make your hydrangea blooms turn blue, while adding lime can make them turn pink.


Growing hydrangeas indoors can be a fun and rewarding experience. With the right variety, soil, and care, you can enjoy beautiful blooms all year round. Remember to choose the right hydrangea variety, prepare the soil, plant your hydrangea in a container with drainage holes, and monitor the temperature, humidity, and soil pH. With a little bit of effort and patience, you can grow stunning hydrangeas indoors.
