Using Hydrangeas Indoors 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.
How are hydrangeas maintained 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.
How long do hydrangeas bloom indoors?
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.
Is it possible to bring hydrangeas indoors during 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.
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.
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.
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.
Can hydrangeas grown in containers spend the winter outside?
You’ll be relieved to learn that winter maintenance needs little work. The best place for your hydrangeas to spend the winter is outside, so now that you’ve put them inside the garage, you may carry them back there.
Hydrangeas are quite cold hardy, thus in the majority of hardiness zones you may leave them on your patio unprotected. Some people can survive in zone 2, where it can reach as chilly as -40 C, perfectly well! Ouch. Although they can all withstand a certain amount of cold, each hydrangea has a different tolerance, so be sure you have a variety that is suitable for your region. Additionally, zone up if you are planting in a container! (See underneath.)
Make sure the containers they’re placed in have enough drainage, as the plants can suffer major harm from inadequate drainage. If not, your hydrangeas will flourish just fine and require the same upkeep and attention as they would in a garden.
Zone up those container plants
Zone up for success if you intend to grow a perennial in a pot! Your plants are less protected from the cold in a container than they would be on the ground. So, for instance, if you are in zone 4, I would advise choosing a plant species that is hardy to zone 3.
How can hydrangeas survive the winter?
One of the most adored Southern belles in the garden is the hydrangea. There are many reasons to enjoy shrubs; they tolerate shade, come in a range of colors, and can add interest all year long. In addition, hydrangeas typically require little maintenance and thrive in challenging growth environments.
Hydrangeas in Winter
Mulch over the hydrangeas in the winter to protect them. Leave faded blossoms alone to add interest in winter.
You may be wondering how to ensure that your shrubs remain secure over the winter due to the unpredictable nature of the weather. I am aware that I am in Georgia. So I asked Ryan McEnaney of Bailey Nurseries the most important winter care issues for hydrangeas, and fortunately, the answers are straightforward:
Is there a time or temperature when it’s “too late” to winterize hydrangeas?
Any form of protection is beneficial. Winter months bring a wide range of temperatures, so if you’ve already experienced any really chilly spells, some harm may have already been done. Despite this, continue to preserve it to ward off any potential threats in the months to come.
Will mulch prevent plants from heaving? Is there a type of mulch that is better for winterizing plants? When spring returns, do I need to remove the mulch?
Plants in the ground and in containers benefit greatly from mulch during the winter. Beyond providing general security, the mulch’s role is to establish an environment that is more consistent with what is going on outside. Temperatures can change from -10 to 30 degrees in some areas of the nation within a week or two. As a result, the root system is disrupted as water molecules in the ground freeze (contract) and then defrost (expand) (heaving). Mulch aids in minimizing those abrupt alterations to safeguard the plants. We advise using wood mulch, oak leaves, or pine straw.
To prevent damage from late spring, wait until after your last frost date to [remove to the mulch]. However, don’t wait too long as heat can develop moisture, which can cause the stems to rot in the absence of air flow.
