Potting and Soil

Choose a pot with good drainage and a size that accommodates the root system of your hydrangea. Fill the pot with a well-draining potting mix formulated for acid-loving plants. Hydrangeas prefer slightly acidic soil with a pH between 5.5 and 6.5.


Keep the soil consistently moist but not waterlogged. Hydrangeas require regular watering, especially during the growing season. Check the soil moisture level by inserting your finger about an inch into the soil. If it feels dry, it’s time to water. Avoid letting the soil dry out completely between waterings.


Hydrangeas thrive in bright, indirect light. Place your plant near a north or east-facing window where it can receive ample natural light. If natural light is limited, you can supplement with fluorescent grow lights positioned a few inches above the plant.

Temperature and Humidity

Maintain a moderate temperature range between 60-75°F (15-24°C) for your indoor hydrangea. Avoid exposing the plant to extreme temperature fluctuations or drafts. Hydrangeas appreciate higher humidity levels, so consider using a humidifier or placing the pot on a tray filled with water and pebbles.


Feed your hydrangea with a balanced, water-soluble fertilizer formulated for flowering plants. Follow the package instructions for the correct dilution and frequency of application. Fertilize your hydrangea once a month during the growing season, typically from spring to early fall.

Pruning and Maintenance:

Regular pruning helps maintain the shape and size of your hydrangea plant. Prune after the blooming period, removing any dead or damaged stems. You can also prune to encourage bushier growth and more prolific blooming. Remove spent flowers to promote new growth and blooming.
