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!
Should I remove the wilting flowers from my hydrangea tree?
Your hydrangea shrubs’ blossoms appear to be withering or turning brown. No need to worry—this is merely a signal that it’s time to deadhead—remove the blossoms from the plant.
Deadheading hydrangeas doesn’t cause any damage to the plants at all. Flowering shrubs stop producing seeds when the spent blooms are removed, and instead focus their efforts on developing their roots and leaves. You will be doing your hydrangeas a favor by deadheading because this strengthens and makes plants healthier.
How is a potted hydrangea tree maintained?
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.
When should my hydrangea tree be pruned?
Depending on the kind you have, you must prune your hydrangeas correctly. Different hydrangea varieties need to be pruned at various times of the year.
For instance, you should hold off on pruning smooth hydrangeas like Annabelles until they are through blooming. All summer long, new blooms will result from pruning done in the late fall or early spring, before new growth starts.
Big Leaf and Oakleaf hydrangeas should only be pruned in the early fall to avoid cutting off buds that might otherwise prohibit summer blooming. It’s advisable to prune these hydrangea varieties as soon as they finish blooming.
Although Paniculata or PeeGee hydrangeas are a little more adaptable, they should still be clipped in the early spring before new growth starts.
How far back may a hydrangea tree be cut?
I have a hydrangea tree, but because the branches are excessively long, they bend downward to the ground when it rains. Can I prune branches back, and if so, when should I do it?
Yes, you can prune it, but first it’s important to define a hydrangea tree so you can understand how and why.
A panicled or PG hydrangea (Hydrangea paniculata) is actually a hydrangea tree that has been deliberately pruned to resemble a tree. Depending on the cultivar, it develops huge, elongated clusters of white or lime-green blooms at the tips of its branches in the summer that progressively turn pink or even scarlet in the fall. Since few other kinds of hydrangea have stems robust enough to create decent trees, it’s very much the only one used in this method.
The panicled hydrangea typically develops into a sizable multi-stemmed shrub. It grows an abundance of branches from its base and develops an erect, spreading shape over time, eventually reaching a height and diameter of up to 15 feet (5 meters) after 15 to 20 years. It’s obvious that it’s a shrub because it doesn’t resemble a tree in its natural state.
The nurseryman selects a young specimen with a strong central branch and starts to shape it into a hydrangea tree “prune it until it yields. He cuts off any more branches and any secondary branches that develop on the branch that will eventually serve as the trunk. During the first few years, staking is frequently required to maintain the trunk’s strict verticality. He starts trimming the top of the plant as well after the trunk has grown to the appropriate height, which is often 4 to 5 feet/1.2 to 1.5 meters. Because of this, the hydrangea is compelled to grow numerous branches at the top of a primary stem, or new trunk.
The process of making a hydrangea tree is time-consuming and significantly raises the price of the plant.
If you like, you can prune a hydrangea by yourself to resemble a tree, but it will take some time.
If you want to keep a hydrangea tree healthy, you’ll need to be prepared to prune it on a regular basis. If you don’t, the branches will grow too long and begin to bend under their own weight, as you’ve seen, and they may even break off, especially when there is heavy snow on top of them.
In your situation, it would be advisable to prune your hydrangea tree before winter because it is overgrown and the limbs are already bending from the weight of the plant. Simply prune all branches back to a distance of 6 to 8 inches (15 to 20 cm) from the top of the trunk in October or November if you don’t want them to risk breaking off in snowy or icy conditions.
Starting pruning early in the spring as opposed to the fall will help your hydrangea tree survive the winter. This is because you’ll want to keep the panicled hydrangea’s dried flower heads until spring because they are lovely over the winter.
Make it a practice to trim back all the branches early in the spring, before the leaves emerge, by 6 to 8 inches (15 to 20 cm). This will give your tree the intended effect, which is typically a ball of greenery topped with blossoms at the summit of a short trunk. Panicle hydrangeas bloom from new growth that begins to appear in mid-spring, so they will continue to bloom profusely even after harsh early-spring trimming.
In order to keep its tree-like look, with a clearly “Remove any suckers that develop at the plant’s base and any growth that develops on the trunk itself. This type of pruning is suitable for all seasons.
The optimal growing conditions for panicled hydrangeas are full sun or very little shade in virtually any well-drained soil. They can thrive in zones 3 to 8 and are cold hardy.
What occurs if hydrangeas are not pruned?
If and when you prune is the key to happy, healthy hydrangea flowers. Of course, fertilizing and offering the ideal environment have a lot to recommend them. However, if you don’t prune properly, your efforts will be in vain. Deadheading is not the same as trimming. Pruning refers to more drastic cutting to preserve shape or remove dead growth. However, feel free to discard spent blossoms or cut fresh ones to use in arrangements.
Hydrangeas can bloom on either fresh wood or old wood, depending on the species. The wood from which they blossom determines whether and when to prune.
Old wood-blooming hydrangeas do not require pruning and benefit from it. They’ll blossom more abundantly the next season if you leave them alone. But feel free to deadhead or gently thin. Just keep in mind that while new growth may appear, it won’t bloom until the following season. In our region, four different species blossom on aged wood. Additionally, they are not limited to the hues displayed here.
Climb using suckers. On your wall or trellis, resist the desire to remove the dormant growth.
The flower heads are more conical in appearance, and the leaves are large and resemble oak leaves. It’s a pleasant surprise for a hydrangea when its leaves turn reddish-orange in the fall.
They are very comparable to lacecap types, but smaller and with more compact leaves.
Pruning should be done in late winter or early spring on hydrangeas that bloom on new wood. Trim back to two feet to prune to shape. The next season’s blossoms are produced by strong, fresh growth that is encouraged by trimming. In our region, there are two types that bloom on fresh wood. They are also not restricted to the colors displayed.
Oakleaf variants are not included in cone-shaped blooms. Keep the blooms on throughout the winter to provide interest; even dried out, they are quite lovely.
regarded as a wild kind. They often have smaller blooms and leaves than Bigleaf variants and are completely white. They enjoy full sun and can grow very tall.
Knowing whether or when to prune now will help you avoid the disappointment of a hydrangea that doesn’t blossom. Don’t forget that a robust shrub will produce more gorgeous blossoms if it has well-draining soil and good organic fertilizer. Come on in, and we’ll show you where to go to develop your green thumb.
Do I need to remove Brown hydrangea blossoms in the winter?
Myers advises leaving the dried blossoms on your hydrangeas if you’re looking for an easy way to spice up your winter yard. Bigleaf hydrangeas produce their final rush of flowers in the fall, so to enjoy the dried blossoms all winter long, stop deadheading at that time. To aid in the production of healthy buds in the spring, these can be removed.

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.
