Large shrubs, hydrangeas are typically cultivated in beds. However, with the correct care, you may successfully grow a tree hydrangea in a pot:
- Select a container with a minimum diameter of 16 to 24 inches (40 to 60 cm). Every few years, repotte to a bigger container. Use a strong container that won’t crack as temperatures change if you plan to leave the plant outside all winter.
- Make sure the potting soil will drain adequately and use top-notch potting soil. Compost might be added; hydrangeas prefer fertile soil.
- Drink plenty of water, especially in the summer. Don’t allow the soil to become overly dry.
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 long can hydrangeas be grown in pots?
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.
What size container should I use for a hydrangea?
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.
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.
Why are the hydrangeas in my pots 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.
How is a hydrangea tree cared for?
Hydrangeas in bloom are a surefire indicator of summer. Nothing compares to the stunning sight of hydrangeas in bloom in a range of colors. Every summer garden looks beautiful with the white, blue, pink, or purple blooms coupled with the vibrant green foliage.
How wonderful would it be to see hydrangeas on trees instead of the usual low-growing hydrangea bushes? The good news is that you can. How to grow a hydrangea tree is described here.
Instead of large spherical blossoms, the Grandiflora variety of Hydrangea paniculata develops white conical flowers. It has the potential to reach a height of 25 feet with moderate pruning and good maintenance! Your greatest option for cultivating a hydrangea tree is Grandiflora, also referred to as Pee Gee Hydrangea by gardeners.
Prepare yourself for success before you plant. The USDA plant hardiness zones 5 through 8a are ideal for hydrangea tree growth, so check your zone. Make careful to pick a location with consistent bright light because hydrangeas enjoy full sun for the majority of the day and a little afternoon shade.
Typically, hydrangeas prefer rich, permeable, moist soil. To promote healthy growth, aerate the soil with Espoma’s All-Purpose Garden Soil and apply Espoma’s Bio-tone Starter Plus. If you’re planting numerous trees, make sure to thoroughly water them and give each hydrangea a minimum distance of 3 to 10 feet.
Pruning is one of the most crucial aspects of hydrangea tree growth. The training, pruning, and correct maintenance are what distinguish a hydrangea shrub from a tree. Springtime is the best time to prune. Remove old twigs that failed to develop wholesome growths and suckers from the tree’s trunk. Trim branches so they have two or three nodes each to keep your tree looking tidy (small bumps on the branch that signify growth).
Although it requires a lot of sunlight, your hydrangea tree will offer some shade on particularly sweltering summer days. Keep the soil moist to prevent drooping leaves and blossoms because greater sunlight requires more water. Before the height of the growing season in the spring, prune your hydrangea tree.
Growing a hydrangea tree sounds like the next step for you if you love your hydrangeas and want to see more than a standard shrub!
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.
