How To Plant Hydrangeas In Containers

If you’ve ever received a hydrangea in a foil-wrapped pot, you likely loved it for a few of weeks before seeing it sadly wilt. You might conclude from it that hydrangeas are poor container plants.

Most hydrangeas that are given in pots as gifts do poorly because they are kept indoors for too long. Others perish because they were grown in a greenhouse and are not cold hardy in your region of the country, even if they are planted outside.

However, hydrangeas can make wonderful potted plants if you choose wisely. What you should know is as follows.

Potted Hydrangea

You can utilize hydrangeas in containers in your garden on stands, decks, or patios. This plant looks classy perched atop an antique column.

  • Choose a location for the hydrangeas first. You may move them around, which is one of the benefits of growing them in pots. This also makes it simpler to provide hydrangeas with the ideal growing conditions because many of them prefer morning sun and afternoon shade. Additionally, you can arrange them to beautify a patio or other area for a celebration or special event.
  • If your pots won’t stay in the same spot all the time, search for containers with wheels on the bottom or think about durable, rolling plant stands. Don’t forget that after adding dirt and plants, containers can become quite heavy, and watering them will make them even heavier.
  • For your hydrangea, pick a large container with a diameter of at least 18 to 20 inches. The plant usually wilts in small pots like the one your gift hydrangea arrived in because they typically dry out too quickly. Drill drainage holes into the bottom of your container if there aren’t any already. Rotting can result from water that accumulates around the roots.
  • Next, pick a variety that is advised for your area. (This is a general guideline for growing any plant well.) To choose the best varieties for your garden, read plant tags or conduct online research. Some hydrangea varieties can grow in USDA zones 3 and 9, while the majority are hardy in zones 4 to 8.
  • Although using miniature hydrangeas in pots isn’t required, you might wish to if you have a small yard. Not only do hydrangeas grow tall, but they also become bushy. If not, prepare to prune your plants as they develop. Be careful when conducting your research; see if your variety blooms on new or old wood. You’ll lose the flowers for the following year if you prune at the incorrect time of year.
  • Use high-quality potting soil that contains organic materials rather than regular garden soil. If you want the hydrangea to continue growing, don’t plant it higher or deeper than it was in the pot it came in. Make sure there is space below the pot’s rim so you can water.
  • To get rid of air pockets, gently compact the dirt close to the roots.
  • Water your hydrangea well whenever the top inch or so of the potting soil feels dry. But being underwater is preferable to being overwatered. When they are thirsty, hydrangeas may wilt to let you know. However, this can stress them out, so check them every other day or so. You’ll eventually get a sense for how frequently to water. In times of drought or extreme heat, you might need to increase your watering.
  • Although hydrangeas don’t require a lot of fertilizer, you can feed your plants once or twice a year with a commercially available composted manure, a 10-10-10 granular fertilizer, or a slow-release balanced fertilizer. If you reside in a warm environment, wait until after July or August to fertilize. Gardeners in the north can get away with applying fertilizer just once, in June or July. Feeding hydrangeas later, when they should be starting to go dormant for the winter, promotes fragile, fresh growth.
  • If your plant already appears to be ill or unhealthy, don’t fertilize it—you’ll just increase its stress. Try to solve the issue instead.

Do hydrangeas thrive in containers?

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 better for hydrangeas to grow in the ground or in pots?

Maintaining hydrangeas in pots is easy, and they provide a beautiful addition to a deck or patio’s color and structure. Additionally, they go well with modern gardens as well as country gardens.

You already know that hydrangeas want moist, organically rich soil that doesn’t dry out over the summer if you’ve read up on how to cultivate them. They thrive best when planted directly into the ground because containers have a tendency to dry out much more quickly.

But that doesn’t mean you can’t use these blooms to make a lovely container arrangement. Simply make sure to take good care of them, choose your compost wisely, and plant them where they will thrive. Additionally, some kinds are better suited to these circumstances. Everything you need to know about taking care of hydrangeas in pots is included in this guide.

When do hydrangeas bloom?

The type, cultivar, planting zone, and hydrangea blooming season all affect when they bloom. The majority of hydrangeas with new growth form buds in the early summer in preparation for blooming the next spring, summer, and early fall. Hydrangeas may stop flowering in the heat of the summer in hot locations, but they will blossom again in the fall.

How do you cut back hydrangeas?

Hydrangea plants don’t require pruning if they are allowed plenty of room to develop in the garden. Only the periodic clearance of dead wood is necessary.

Do you need to deadhead hydrangeas?

Your hydrangeas will continue to bloom into the fall if you deadhead them. Hydrangeas make wonderful cut flowers, so there’s no need to wait until the flower wilts. Leave the early fall blossoms alone so they can fade naturally. In the days leading up to your freeze date, you don’t want to promote new growth.

How do you control hydrangea color?

The distinction of hydrangeas is that you can modify their color. But keep in mind that not all hydrangea varieties can change their color. H. macrophylla, a species of bigleaf hydrangea, responds to changes in soil pH. Hydrangeas can absorb aluminum thanks to a low soil pH, which gives the blossoms a lovely blue hue. Reduce the pH of your soil by mixing in sulfur or peat moss to enhance the number of blue hydrangea flowers. Throughout the growth season, you can keep amending your soil with extra aluminum sulfate. When you add ground limestone to boost the pH, pink and red blooms shine.

You may precisely modify your hydrangea color using a soil pH test. To avoid the plant from being harmed, keep the pH level below 7.5. In the fall, all hydrangeas will naturally fade regardless of the modifications you’ve made. Don’t worry, the plant will display vibrant, new blossoms once more in the spring.

Can hydrangeas grow in shade?

Although they won’t blossom in complete shade, hydrangeas prefer dappled or infrequent shade. How much sun do hydrangeas need is more important to consider than whether they love the sun or the shade. Your hydrangeas require more sunlight the further north in your garden you are. A general guideline is six hours of sunlight each day. However, southern hydrangeas can thrive with just three hours of sunlight per day.

Can hydrangeas grow in full sun?

While hydrangeas prefer morning sun, they struggle in the hot, afternoon sun. For these gorgeous creatures, partial shade in the later hours of the day is optimal.

Can you grow hydrangeas in pots?

Even if you don’t have enough room in your garden to cultivate hydrangeas, you can still enjoy these lovely blossoms by learning how to grow hydrangea in a pot. As long as you follow the fundamentals of caring for hydrangeas, the procedure is rather straightforward. Select a pot with at least an 18-inch diameter to accommodate the mature size of the particular hydrangea you are growing. In order to maintain the constant moisture level that hydrangeas demand, look for non-porous containers. Excess water will be able to adequately drain thanks to drainage holes. Consider growing dwarf hydrangeas like Buttons ‘n Bows, Mini Penny, and Little Lime.

How do you keep hydrangeas from wilting?

Morning irrigation on a regular basis can assist stop withering. Some hydrangea cultivars simply can’t stand the heat. No matter how much water you give them, they will begin to wilt in the afternoon heat. Mulch applied in layers can help soil retain moisture and stay cool. You shouldn’t be concerned if your hydrangeas bloom again once the day cools. A little midday wilting is preferable to overwatering and drowning your hydrangeas.

What kind of soil works best for potted hydrangeas?

We automatically think of huge plants when we think of hydrangeas because of their enormous foliage and larger-than-life blooms. However, hydrangeas actually come in not one, not two, but three sizes!

Regardless of the size of your area, locate the ideal hydrangea. Even hydrangeas can be grown in a container.

1. Small Is Everything. Choose a hydrangea that will grow well in your restricted space. Dwarf variations are small yet mighty little beauty. To select the ideal dwarf hydrangea for you, browse our Hydrangea Variety Guide. Then, locate a location that has the appropriate level of illumination.

2. Bold, large, and riddled with holes To create a statement, choose a pot or repurpose a container. Ensure that it has drainage holes alone.

3. Gold Soil Solid. Choose a high-quality, organic potting soil for hydrangeas because they require well-draining soil to thrive. If it possesses Myco-toneTM mycorrhizae, which use 30% less water than conventional soils, it gets bonus points.

5. Decide on the necessities. Water hydrangeas in containers when the top inch of soil becomes dry or when the plant starts to wilt. Feed your hydrangeas once a year in June or July with an organic fertilizer for the finest hydrangea care. Feed your hydrangeas with Holly-tone if you want them to be blue.

Big blossoms in a small space! Just picture how beautiful your hydrangeas will appear at your Memorial Day party shimmering in the sun or glimmering in the moonlight at your summer garden gatherings!

Can I put my hydrangea plant in a pot outside?

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.

How long do hydrangeas in pots 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 blooms for the majority of the summer and can 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 morning sun 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 earlier than some other varieties. 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 cool 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 move the plants or transplant one from a pot to the ground, the hydrangeas may not bloom for a year or even two. Hydrangeas can produce large blooms in their first year. This does not imply that their time of blooming 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.
