Hydrangeas, prized for their magnificent blossoms, have long been produced successfully as blooming indoor houseplants. Their blooms have a softball-like shape and size, measuring 5 to 6 inches in diameter. The explosion of color produced by the double-flowered variety is spectacular.
Can hydrangeas in pots be kept indoors?
The good news is that as long as you can meet the plant’s fundamental requirements, potted hydrangea plants are suitable for indoor cultivation and are rather simple to care for.
How are hydrangeas maintained indoors?
Water: While the plant is growing and blooming, keep the soil equally moist but not saturated. Roots are typically tightly packed in pots, so water frequently. Because lime will make the soil alkaline, use water without any lime. When the hydrangea is dormant in the winter and needs less water.
Room humidity is average (around 40-45 percent relative humidity). Use one of these simple methods to increase humidity for your houseplants if the air inside is dry.
Maintain a cold environment for your hydrangea plant to encourage more flowering. ideally lower than 60F/16C.

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.
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.
Can hydrangeas in containers endure the winter?
Hydrangeas in potsWinter Care Bring potted plants indoors before the first frost for the greatest hydrangea winter protection. They can stay outside and be protected by covering the entire pot and plant if they are too heavy to transport.
How frequently should a house hydrangea be watered?
To help maintain moisture when planting in a container outside, choose a light-colored ceramic pot. Dark colors heat up more quickly. Make sure a drainage hole is present! At least three times every week, the hydrangea needs to be thoroughly watered. Never simply water the plant in one spot; always water it all the way around the container. The pot’s bottom ought to leak water. Never leave it submerged in water because the roots will rot away.
Can indoor hydrangeas be planted outdoors?
Mophead hydrangeas can be cultivated outside wherever the wintertime temperature stays above -15oC because they are hardy (5oF). However, as they were grown in greenhouses and given fertilizer to induce early flowering, potted hydrangeas sold as houseplants may require some time to acclimate to life outside before being put out. Place them outside in their pots during the day and bring them inside at night to harden them off for one to two weeks before to planting. Hydrangeas that have been grown for outdoor planting can be planted immediately. Mid- to late April, when the soil has had time to warm up, is the ideal time to plant mophead hydrangeas outdoors.
The optimal conditions for hydrangeas are shade from the sweltering afternoon sun and moist, well-drained soil. They are therefore excellent alternatives for shady gardens, and in mid- and late-summer, their dramatic spherical flowerheads are absolutely gorgeous. Regularly water hydrangeas, especially during dry spells, and in the spring or fall, mulch with compost or other organic material.
Because of the soil’s pH (acidity or alkalinity), pink and blue mophead hydrangea blossoms have the unusual ability to change color. The blossoms will be a deeper shade of blue the more acidic the environment is. Flowers turn a gorgeous pink on alkaline soil. The color of white mophead hydrangeas doesn’t alter.
Can indoor hydrangeas be planted outside?
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.
Do you remove the dead blooms from hydrangeas?
Your hydrangea shrubs’ blossoms appear to be withering or turning brown. No need to worry—this is merely a signal that it’s time to deadhead—remove the blossoms from the plant.
Deadheading hydrangeas doesn’t cause any damage to the plants at all. Flowering shrubs stop producing seeds when the spent blooms are removed, and instead focus their efforts on developing their roots and leaves. You will be doing your hydrangeas a favor by deadheading because this strengthens and makes plants healthier.
How are potted hydrangeas maintained?
Regularly water potted hydrangeas because they need steady moisture for healthy flower growth and do badly in dry conditions. Water the plant frequently enough to keep the roots moist without keeping the soil damp, which could cause disease issues. When the top soil or potting mix seems dry to the touch, water it. Until you are familiar with how frequently your plant requires water, check the soil more than once every day.
Why aren’t the hydrangeas in my pots blooming?
The majority of types flower on “old wood,” or wood that grew and produced flower buds the year before. Thus, flower buds may be harmed by early or late freezes or harsh winters. The incorrect timing of pruning is another factor in hydrangeas’ failure to bloom.
