When hydrangeas outgrow their pot, they must be repotted in order to maintain their health. This often occurs every one to two years.
Once it has done flowering in the fall, carefully remove yours from the container it is now in. Make sure the new garden planter has drainage holes and is about an inch bigger in diameter than the old one. Plant it at the same depth as before.
A hydrangea can it live in a pot?
Selecting the appropriate-sized planter for your hydrangea is the first step in planting. Because their roots are vigorous and quickly fill smaller containers, hydrangeas do not grow well in smaller containers. Additionally, smaller containers dry out far too quickly for hydrangeas. Generally speaking, we advise purchasing a medium to big planter that is at least 2 feet wide.
Make sure there are drainage holes at the bottom of the planter once you’ve chosen it. It is necessary for hydrangeas to be grown in pots because they will decay if the soil lacks adequate drainage. To aid in drainage, we also like to add a layer of rocks at the bottom. The most important stage for healthy plants is proper drainage.
You must then purchase soil made especially for planters. In containers, topsoil can occasionally fail to drain properly. Compost can be applied to the soil to provide additional nutrients.
Plant the hydrangea at the same depth in the soil as it was in the pot it was previously growing in when putting it in the pot. To water the planter without the water washing out the top, leave at least 2 inches between the top of the soil and the top of the planter. To assist the plant stay firmly in the pot, gently press down on the dirt around it to remove any air pockets.
After a potted hydrangea blooms, what should you do with it?
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 be kept in pots during the winter?
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. Foam insulation is one way to safeguard your potted plants.
Purchase hydrangea plants at garden centers near the end of the summer when they are on sale (if budget is a factor).
This may not apply to you if you are ready to go all out with hydrangea growing during the height of their season. Here’s a tip, though, if you’re trying to keep your gardening spending to a minimum: buy your plants near the end of the season when they’re heavily discounted.
I cautiously gathered my three hydrangea plants. Each of them was bought when they appeared to be quite dejected and abandoned at the store. Look what they look like now after I purchased them for a steal of a deal!
Place hydrangeas in a large enough pot to allow for good growth.
I have three different types of hydrangeas, as you can see in the photo above. They differ in terms of the size they can reach, the size of their leaves, the period during which they bloom, and the colors they exhibit.
The one thing they all have in common, though, is the requirement for sizable containers for growth.
It is advised to plant hydrangeas in pots with a depth and diameter of at least 40 to 60 cm since these dimensions will provide the roots room to spread out and thrive.
The pots to the left and right are each 17 inches tall and 20 inches in diameter. Here is a comparable product that you can buy online.
Similar to this one, the tall one in the middle is 15 inches in diameter and 22 inches tall.
Make sure the hydrangea pots drain well
Make sure the pots your hydrangeas are in have a drainage hole at the bottom because they need well-drained soil to thrive. If they don’t, pierce a few holes in the bottoms with a drill.
Use a potting soil mix that is formulated for plants in pots
When planting the hydrangeas in their new pots, use high-quality potting soil that has slow-release fertilizer (plant food) mixed it, such as this variety from Miracle Grow. Sprinkle in some slow release fertilizer plant food, such as this Shake n Feed, at the start of each spring.
I once heard that while water keeps plants alive, if they aren’t also supplied food, their nutrients will be lost. It’s just like us! We can survive by drinking water, but we need food to thrive. As I take care of my indoor and outdoor houseplants, I keep that idea in mind.
Place your hydrangeas in pots in a semi-shady location
Hydrangeas respond very differently depending on their environment. They dislike excessive sun exposure!
Our tiny terrace receives some afternoon sun but is primarily sheltered. They appear to be really content there in the shade.
Depending on where you live, hydrangeas require a different amount of sun. The benefit of having them in pots is that you may reposition them until you discover the location where they will thrive.
Water hydrangeas in pots frequently, so the soil doesn’t get dry during their blooming time
Hydrangeas need to be watered every day while they are blooming. I even watered them twice a day, once in the morning and once in the evening, during the unusually hot weather we saw this summer. That maintained their wellbeing.
I water them with a garden hose nozzle and my go-to lightweight, kink-free garden hose, making sure to keep the water at the roots. Watering the leaves should be avoided since it could transmit illness. Until water starts to start draining out of the container’s drainage holes and onto the patio, water it well.
Harvest hydrangea blooms to encourage more healthy growth
Hydrangea blooms can be cut and used as lovely cut flowers, like many other flowers can. Additionally, by removing the blossoms, you promote more new, healthy growth.
I discovered this incredibly useful video that demonstrates how to cut hydrangeas precisely for flower arrangements and even how to resuscitate a hydrangea bloom that has withered.
Trim hydrangeas in the Fall for nice growth the next Summer
I drastically prune my hydrangeas in the fall because I don’t want them to grow to enormous sizes. Then, it’s so much fun to see them grow and blossom once more in the Spring and Summer!
How to prepare hydrangeas for Winter
In order for hydrangeas to blossom, a cold time is necessary. I don’t need to do anything specific to get them ready for Winter because our winters in Zone 8 are mild. All winter long, I simply put them in their pots outside in their designated positions on the deck! They are shielded from windstorms by being cut back in the fall and placed in front of the patio barrier.
Look into the best winter hydrangea care practices in your area for the climate you live in.
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.
Are hydrangeas better 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.
How many years do hydrangeas live?
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.

Examine the blooms for signs of damage.
Look for hydrangeas at the store that have vibrant, robust green leaves and bouncy blossoms. Check the petals for any brown spots, which would signify sun damage, advises BloomThat’s production director Callie Bladow. “Additionally, because cut flowers are stored cold, keep an eye out for black petals that could mean the blooms have been in contact with a refrigerator’s side. A flowering hydrangea should feel solid, not flimsy or spongy.” A healthy bouquet should last up to two weeks if you select one.
Cut garden-grown flowers with a sharp floral knife.
If you’re fortunate enough to have garden hydrangeas, you may easily bring them inside for a lovely arrangement. While working outside, cut them on the bias (a 45-degree angle) using a sharp flower knife or clean kitchen shears, then put them in a dish of lukewarm water. The optimal time of day to trim hydrangea blossoms, according to Bladow, is early in the day. “Leave the others to continue blooming and just select the most fully developed and mature blooms. Hydrangeas with full flowers will appear more “papery” than those with young buds.”
Prep them with alum powder.
The sap that hydrangeas create at the base of their stems needs to be sealed off in order for them to absorb water. After making a bias cut in the stem, Bladow advises dipping it in alum powder, an onion powder that can be found in the spice section of your local supermarket. “All that’s needed is a quick dip of the stem’s bottom, followed immediately by the vase.” If you don’t have alum powder, you can get the same result by dipping the stem in boiling water for around 10 seconds. Additionally, cut the leaves off the stem because they will use up all the water in the vase.
Get creative arranging with different flowers.
You can choose to use a traditional arrangement of only hydrangeas or you can try blending in other flowers or utilizing unusual vases. Bladow explains, “I adore utilizing glass apothecary jars with larger bases and petite vase necks. “Another way we enjoy using hydrangeas in our designs is as grids for other flowers. Simply insert them into the flower head; the hydrangea’s multiple stems will hold other flowers in place.” Hydrangeas can be arranged with any kind of flowers. She suggests combining some foliage, such as lemon leaf or variegated pittosporum, with roses, dahlias, and freesia.
Change the water daily.
According to Bladow, hydrangeas prefer chilly water, which should be replaced every other day with a new snip of the stems. You can fill the vase with some plain cane sugar or flower food from your cupboard. Keep your arrangement away from harsh sunlight. Additionally, Bladow advises soaking the entire hydrangea for around 45 minutes in cool water if your flowers are acting downcast. Shake them off, trim the bottom of the stem, and then submerge them in flower food-infused water. Your hydrangeas’ lifespan could be extended and they might even come back to life.
