Do hydrangeas thrive in containers? Given that potted hydrangeas received as gifts rarely survive longer than a few weeks, it’s a reasonable question. The good news is that they can, given the proper treatment. Growing hydrangeas in pots is a great idea because they can grow to be fairly large and have beautiful blossoms all summer long. Learn more about container-grown hydrangea plants and how to take care of hydrangea in pots by reading on.
How long does a hydrangea in a pot last?
In U.S. Department of Agriculture hardiness zones 5 through 9, hydrangea (Hydrangea spp.) gardens are adorned with enormous, vibrant blooms. These shrubs, which share their frothy blossoms for the most of the summer and may grow between 4 and 12 feet tall with proper care, can live for decades.
Hydrangeas are hardy shrubs that, with proper care, can survive for up to 50 years. They require frequent watering during the growing season and prefer early light but afternoon shade. After the blossoms have faded, prune them in the fall so that they will have sturdy stems for the summer after. The hydrangeas may lose their blooms for a year while the plants heal if they are pruned when they are in bloom.
Common hydrangeas, sometimes known as bigleaf hydrangeas, bloom in a variety of hues, including blue, pink, and purple. These hydrangeas typically start to bloom in May, which is sooner than some other kinds. Usually, the plants keep producing blooms until July. According to the characteristics of the soil, bigleaf hydrangeas are known to shift their bloom colors; a plant that blooms pink one year may bloom blue the following. Aluminum sulfate, which is added to the soil, promotes blue flowers, whereas hydrated lime, which is added to alkaline soils, promotes pink blossoms. Ayesha, Nikko Blue, and Preziosa are cultivars.
Longer blooming than other hydrangeas, the smooth hydrangea (Hydrangea arborescens) frequently displays color from early June through September. The cultivars “Anabelle” in white and “Invincibelle Spirit” in pink are examples. Smooth hydrangeas often bloom on wood from the current year, which means you should severely prune them, in contrast to other hydrangeas that bloom best on ancient wood. Trim them to a height of 6 to 12 inches above ground.
The panicle hydrangea (Hydrangea paniculata) blooms later in the year because it prefers the heat of summer to the mild weather of spring. Panicle hydrangeas often begin blooming in July and continue through September. Their blossoms are initially white, but as fall approaches, they start to turn rusty pink.
However, if you relocate the plants or transplant one from a pot to the ground, the hydrangeas may not bloom for a year or perhaps two. Hydrangeas can produce big flowers in their first year. This does not imply that their time of flowering is over. Once the roots of the plants have recovered from the shock of transplantation, they should begin to blossom. To this end, keep the plants well-watered and treat them with a balanced fertilizer throughout the spring, summer, and fall.

How are hydrangeas maintained indoors?
Remove any foil wrapping from the hydrangea if it was a gift. Remember that hydrangeas offered for sale around the holidays might not be hardy enough to endure indoors. If you’re serious about growing hydrangeas indoors, your chances of success may be higher if you buy them from a nursery or greenhouse.
Place the hydrangea in a sizable pot filled with superior potting soil. Put the plant in an area with lots of light. Hydrangeas planted outside can take some mild shadow, but interior plants require lots of light (but not intense, direct sunlight).
When the plant is blooming, give your potted hydrangea indoor plant periodic waterings, being cautious not to overwater. After blooming, reduce watering but never let the potting soil go completely dry. If at all feasible, use distilled water or rainwater to hydrate potted hydrangea houseplants because tap water frequently contains chlorine and other pollutants.
If the air inside is dry, use a humidifier or put the plant on a humidity tray. Particularly when flowering, hydrangea thrive in a cool environment with temperatures between 50 and 60 degrees F (10 and 16 degrees C). The environment is probably too warm if the leaves start to get brown and crunchy around the edges.
Keep heat sources and drafts away from the plant. While the plant is blooming, feed it once a week with a water-soluble fertilizer that has been diluted to half strength. After that, limit feedings to to one monthly.
It is advised to give hydrangeas a time of hibernation in the fall and winter when growing them as houseplants. Place the plant in a room that isn’t heated and is about 45 degrees Fahrenheit warmer (7 C.). To keep the plant from wilting, the potting mixture should be kept on the dry side but only lightly watered when necessary.
Can you keep hydrangeas in pots inside?
With their large, floppy blooms in springtime shades of pink or blue, those potted hydrangeas from the flower shop or the grocery store are attractive at this time of year (occasionally white). Naturally, many were turned into mother’s day gifts of gratitude.
If you keep the soil moist, potted hydrangeas, also known as florist hydrangeas, are simple to care for inside. Keep them from drying out! You’ll discover that they are thirsty plants due to their enormous leaves and large blooms.
However, avoid letting water collect at the pot’s bottom. Make a few holes in the bottom of a pot that is covered in foil and place a saucer on top. Letting a plant’s roots sit in water is the fastest way to destroy any indoor plant.
The temptation will be to place the plant on a table in the center of the space. And if you like, that’s okay at night. A hydrangea will need more light during the day, though.
The plant should be placed in a well-lit area with shadows and at least some direct sunlight. If you want to remove the flowers once they have faded, it is acceptable. But it’s not essential.
Don’t believe that, though. A hydrangea in a pot is a present that goes on giving. If you live in Zone 6 or farther south, you can plant it outside once all risk of frost has passed. (Zone 5 is also worth attempting. Simply arrange the hydrangea in a safe area.)
These vintage charmers prefer a little sun to bloom outside. Ideal location would have morning sun and afternoon shade. The same goes for a location with damp soil or one that a hose can easily access. Hydrangeas need a lot of water both inside and out.
The primary issue with these lovely shrubs is that they are extremely vulnerable to spring frost damage. When the TV weather forecaster forecasted frost, I’ve been known to store an old quilt or mattress pad by the back door so I could dash outside in the evening and throw it over my hydrangeas to prevent the flower buds from freezing!
Frost is frequently to blame when a hydrangea doesn’t bloom in the spring. Therefore, if it’s still chilly where you live, hold off on bringing your potted plant outside for a little while.
It’s not a problem, though. Both inside and outside, hydrangeas are delightful.
Can you grow a hydrangea indoors outside?
“Indoor hydrangeas,” also referred to as “gift hydrangeas,” began to appear on the shelves of warehouse clubs, box stores, grocery stores, and florists around Easter and continued through Mother’s Day. They literally fly off the shelf because they are so stunning. They also frequently lack tags, labels, and any other kind of information about how to care for them or what to deal with them once they have finished blooming. Even though we don’t sell this particular variety of hydrangea on our website, we’re pleased to share our knowledge and offer some advice if you happen to be the lucky recipient of one – whether as a gift from a friend or as a gift to yourself.
This word is mostly used to denote that this plant should be kept indoors during its flowering period. Hydrangea macrophylla, often known as bigleaf hydrangea, florist hydrangea, or hortensia, is the species most commonly found in indoor settings. Plant breeders create “indoor hydrangeas” expressly for this market for gift plants with an eye on their appropriateness for greenhouse production, premium, disease-resistant foliage, and of course, distinctive and eye-catching blossoms. Because these hydrangeas are meant to be enjoyed indoors, their outdoor or long-term performance is rarely, if ever, taken into account.
Place your indoor hydrangea in a cool, bright area that is out of direct sunlight and away from drafts of hot or cold air for the flowers to stay the longest. Feel the soil surface when you get it home; it should feel relatively damp. It might need some water if it doesn’t and/or if the pot feels particularly light. But before you water it, carefully examine the container: Gift hydrangeas are frequently placed in non-draining attractive outer containers or wrapped with a foil wrapping covering the bottom. In these situations, you should get rid of anything that can collect water in it, water your hydrangea, and then, if you’d want, put it in the ornamental element when it has properly drained.
To ensure that your hydrangea blooms for the longest amount of time, it is crucial to keep it cool and well-watered but never wet.
The spent blooms can either be kept on when the flower color dwindles or they can be removed, depending on your preference. Undoubtedly, some people age more gracefully than others. However, once all of your plant’s blossoms have opened and faded, the show is over; especially if you’re trying to grow it inside, it won’t produce any more flowers that season.
These are not houseplants, despite the fact that they are advertised as “indoor hydrangeas.” In other words, there are very few opportunities to successfully cultivate the hydrangea inside in a conventional household setting. The hydrangea is very unlikely to establish flower buds again given the light and temperature conditions of a home, and the low humidity and poor air circulation can lead to pest or disease outbreaks.
If the weather permits, you might try planting the hydrangea outside, but it’s crucial to keep in mind that the majority of indoor/gift hydrangeas weren’t created with outdoor performance in mind. Many of them are not very resistant to cold, and they will perish in winter in climates colder than USDA zones 7 or 8. It’s obviously preferable to try to grow a hydrangea outside if you have the space, but if you do plant it in the ground, it’s crucial to have realistic expectations for how it will behave. Plant it in a protected area and cover the roots with a thick 2-3″ layer of mulch for optimal results.
In particular, around Mother’s Day.
In addition to their aesthetic appeal in terms of flowers and leaves, outdoor hydrangeas are chosen for their suitability for nursery production and long-term outdoor performance in the outdoor/landscape/garden market. It is probably reasonable to assume that your plant is designed to be put outdoors and will thrive there for a long time if it came with instructions for outdoor planting. In this situation, enjoying it indoors for a few weeks while taking care of it as previously mentioned is absolutely okay.
Do hydrangeas in pots bloom again?
Hydrangeas produce beautiful, vividly colored blossoms on globe-shaped flower heads, and they are frequently presented as gifts during the spring holidays. The United States National Arboretum claims that Hydrangea macrophylla is the most widely cultivated species in the country. Hydrangeas make excellent indoor plants and may be grown outdoors in U.S. Department of Agriculture zones 6 through 8. If you received a potted hydrangea as a present, it was probably already in bloom. After the petals first fade, many people throw away their hydrangeas, but with the right care, the plant will bloom once more.
Why is the hydrangea I have indoors dying?
A hydrangea’s roots can be burned if too much fertilizer is used, which will likely result in the plant dying, turning brown, and drooping.
As such, hydrangeas are not heavy feeders and do not require annual feeding in the same manner as roses do, and doing so can actually be detrimental.
Hydrangeas frequently develop and flower to their full potential if they are planted in healthy soil or the soil has been modified with compost prior to planting.
The hydrangea should flourish if a 1-inch-thick layer of mulch is applied around it to assist retain moisture and supply nutrients to the soil (compost and leaf mould are ideal options).
Only in the following circumstances should fertilizer be used:
- Planting the hydrangea in sandy soil (which is nutrient poor).
- The hydrangea is in a pot or other container where the roots have used up all the nutrients in the soil.
In these two situations, it is recommended to use an all-purpose fertilizer with equal parts nitrogen, phosphorus, and potassium (NPK) that is applied once in the spring and is generally well-balanced.
The roots of your hydrangea can be burned by well-rotted manure, especially if it is added to the soil after planting. However, if the manure is made from poultry manure, it may contain a lot of nitrogen.
To prevent issues, I advise putting compost to the soil as a soil amendment (fresh manure is particularly harmful, always allow it to rot for a year or so before using manure on your garden).
If your hydrangea is exhibiting indications of stress as a result of being recently planted in soil that has been altered with manure, move it to a location with soil and compost, and it should recover.
Reduce the amount of fertilizer used and remove any discolored leaves or blossoms. To assist the hydrangea recover, thoroughly water it in an effort to dilute the soil’s water-soluble nitrogen.
Key Takeaways:
- Most frequently, hydrangea deaths are caused by the soil’s lack of moisture. Because they need their soil to be continually moist, hydrangeas will droop or even die in a dry environment.
- Drought, transplant shock, frost damage, and too much sun can all cause hydrangeas to perish.
- If the pot base doesn’t have drainage holes, potted hydrangeas may succumb to root rot. Small containers may dry out too rapidly and limit root expansion.
- Water hydrangeas liberally, cover them with compost mulch, and keep them out of the sun and wind to help them recover. To encourage healthy growth, remove any growth that has been sunburned or damaged by frost.
