Hydrangeas, especially the vibrant “gift hydrangeas” often seen around Easter and Mother’s Day, are a delightful addition to any home. These beauties, readily available in various stores, bring a burst of color indoors. However, information on their care is often scarce. If you’ve been gifted one of these stunning plants or treated yourself, understanding How To Care For Hydrangeas Indoors is key to prolonging their bloom and enjoying their beauty.

Understanding Indoor Hydrangeas: What Makes Them Special?
The term “indoor hydrangea” primarily refers to Hydrangea macrophylla, commonly known as bigleaf hydrangea, florist’s hydrangea, or hortensia. These aren’t a different species, but rather varieties specifically cultivated for the gift plant market. Plant breeders focus on traits that make them suitable for greenhouse production, such as compact size, disease-resistant foliage, and, most importantly, striking and colorful blooms. The emphasis is on their immediate visual appeal and indoor enjoyment, with less consideration for their long-term performance outdoors or as traditional houseplants. Therefore, understanding their specific needs as indoor plants is crucial for effective care.
Step-by-Step Guide: How to Care for Hydrangeas Indoors
To maximize the lifespan of your indoor hydrangea blooms, mimicking their ideal conditions is essential. Here’s a detailed guide on how to care for hydrangeas indoors:
Light: Bright, Indirect Sunlight is Key
Indoor hydrangeas thrive in bright, indirect light. Avoid direct sunlight, which can scorch their delicate leaves and flowers. A spot near an east-facing window or a north-facing window is generally ideal. If you have a south or west-facing window, place the hydrangea a few feet away to diffuse the intensity of the light. Sufficient light is crucial for maintaining vibrant blooms and healthy foliage.
Watering: Keep Soil Moist, But Not Soggy
Proper watering is paramount for indoor hydrangea care. The soil should be consistently moist, but never waterlogged. Check the soil surface regularly – it should feel slightly damp to the touch. When watering, ensure the water drains freely from the pot’s drainage holes. It’s crucial to remove any decorative foil or outer containers that might trap water at the base, leading to root rot. Water thoroughly when the topsoil feels slightly dry, and allow excess water to drain away.
Temperature and Humidity: Cool and Comfortable
Indoor hydrangeas prefer cooler temperatures to prolong their blooms. Aim for temperatures between 60-70°F (15-21°C). Avoid placing them near heat sources like radiators or drafts from air conditioners. While they appreciate moderate humidity, typical indoor humidity levels are usually sufficient. You can increase humidity if your home is particularly dry by placing the pot on a pebble tray filled with water, ensuring the pot base is above the water line.
Potting and Repotting: Drainage is Essential
Gift hydrangeas are usually sold in adequately sized pots for their initial bloom period. Repotting is generally not necessary while the plant is flowering indoors. However, ensuring proper drainage is crucial from the start. If you notice the plant is sitting in water, immediately remove any obstructions and allow for drainage. When the blooms are finished and you decide to plant it outdoors (as discussed below), repotting into a larger container with well-draining potting mix might be beneficial if you intend to keep it in a pot for longer.
What Happens After Blooming? Caring for Hydrangeas Beyond the Flowers
Indoor hydrangeas are primarily meant to be enjoyed during their bloom. Understanding what to do after the flowers fade is important for their continued care.
Dealing with Faded Blooms: To Snip or Not to Snip
As the vibrant colors of your hydrangea flowers begin to fade, you have a choice: you can either leave the spent blooms on the plant or gently snip them off. Aesthetically, some varieties age gracefully, while others might become less appealing as the color diminishes. Removing faded blooms won’t encourage new blooms indoors during the same season, but it can improve the plant’s appearance.
Planting Outdoors: Giving Your Hydrangea a Second Chance
Despite being sold as “indoor hydrangeas,” these plants are not true houseplants for long-term indoor growing. The low light levels, temperature fluctuations, and dry air in most homes make it challenging for them to rebloom indoors. However, you can attempt to plant your hydrangea outdoors if your climate is suitable.
Most gift hydrangeas are Hydrangea macrophylla varieties, which are typically hardy in USDA zones 6-9, but some are less cold-tolerant (zones 7-8 being safer). If you live in a suitable zone and the weather permits, planting it outdoors offers a better chance for long-term survival. Choose a location with morning sun and afternoon shade, and well-draining soil. Amend the soil with compost to improve its quality. Water regularly after planting, especially during the first year as it establishes its root system. Applying a 2-3 inch layer of mulch around the base can help retain moisture and protect the roots, especially in colder climates.
Long-Term Indoor Expectations: Managing Realities
While technically possible to keep an indoor hydrangea alive indoors after blooming, reblooming indoors is highly unlikely under typical household conditions. The plant needs a period of dormancy and specific temperature cues to set new flower buds, which are difficult to replicate indoors. Focus on enjoying the blooms while they last, and consider outdoor planting if feasible for your location.
Conclusion: Enjoying the Indoor Hydrangea Gift
Caring for hydrangeas indoors primarily involves providing the right light, consistent moisture, and cool temperatures. These steps will help you maximize the enjoyment of your gift hydrangea while it’s in bloom. While their lifespan as indoor plants is limited, understanding their needs and considering outdoor planting can extend their beauty beyond their initial indoor display. Appreciate the vibrant colors and unique charm of your indoor hydrangea, and with proper care, you can savor its beauty for as long as possible.
