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.
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.

Can you leave hydrangeas in a pot?
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.
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.
Do hydrangeas in pots reseed annually?
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 in my container 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.
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 long do hydrangeas bloom for?
The lacecap and mophead varieties of French hydrangeas are depicted in the blue bowl, respectively (galvanized bucket). We adore these options for gorgeous color: The first three are “Bluebird,” “Big Daddy,” “Endless Summer,” and “Nikko Blue.”
We love beautiful French hydrangeas just as much as you do. These impressive blooms virtually arrange themselves, but if you cut them prematurely or improperly prepare them, they’ll deflate quickly. Take our suggestion and gather flowers in the morning for arrangements that will last for a while (approximately two to three days for fresh cut flowers). Choose ones that are transparent and vibrant. The strongest blooms are mature ones that have a little papery texture. The stems should be cut at an angle and placed right away in a pail of water. Place them right away or keep them for up to two days in a cold, dark place (like a garage). Try one of these suggestions as soon as you notice the flower heads starting to droop.
Bathe in alum In order to arrange hydrangeas, Kathy Thomas, a floral designer with KSR Designs in Macon, Georgia, uses the following technique: To aid in promoting water uptake, she coats the bottom 1/2 inch of each stem in alum powder, which can be bought in the grocery store’s baking section.
Take a Bath Blooms should be submerged in water for 45 minutes, stems and all. The best technique to revive previously arranged flowers is to do this.
Calm Down Fill vases with two parts ice to one part water to cool flowers as the temperature soars.
How large do hydrangeas in pots get?
Temporary A temporary planting can be done in almost any container! You are ready to go as long as it can contain soil and has a hole (or several holes) large enough to let excess water out. This implies that you can make use of troughs, antique-style containers, or the DIY container you found on Pinterest.
Use AquaPots if you’re more of a laid-back grower. This top-notch, self-watering equipment makes growing hydrangeas in containers a snap. The containers themselves are stunning, but the hydrangeas also appear great and fresh because of the steady flow of water. This approach might truly save you time because it’s no secret that container gardening requires a little extra work due to the setup of drip irrigation or frequent hand watering. It should be noted that AquaPots are only suggested for short-term plantings in cold locations due to the risk of cracking if you don’t empty them before the first winter freeze.
Permanent If you reside in an area that gets frost, the container material is crucial. Pick a frost-resistant pot; many will have a sticker to indicate this. Just stay away from clay, terra cotta, or ceramic pots if you’re not sure if your container will work. When freezing temperatures come, containers that aren’t frostproof frequently break or shatter, leaving the roots of the plants exposed to the bitter cold.
If you’re fortunate enough to reside somewhere that doesn’t freeze, you can utilize AquaPots for long-term planting. Hydrangeas can really be planted in any clay, terra cotta, or ceramic container that catches your eye.
The size of your container is important since the plant’s roots will require space to expand while it is there. We’ve discovered that pots that are at least 16 to 24 inches broad and deep may frequently hold a sizable hydrangea for a few years.
Before planting the hydrangea, transfer any hefty containers—think elaborate and vintage—into position. Additionally, plan to have a dolly on hand to transport it easily if you want to overwinter it in a more protected location.
