The various benefits of climbing hydrangea make it a favorite vine of both homeowners and professionals. When fully grown, a climbing hydrangea can reach a height of more than 50 feet and clings to almost any kind of structure. The hydrangea’s glossy, deep foliage is contrasted by the dinner plate-sized white blooms that emerge in the middle of summer and continue for many weeks. When the blossoms and leaves are lost for the winter, the hydrangea’s hairy, crimson bark offers intrigue. Despite the delayed establishment of climbing hydrangeas, it’s critical that they get off to a strong start with a firm trellis to climb on.
Obtain a climbing hydrangea from a nursery or garden center. Make sure the hydrangea has sparkling, vibrant leaves and vines. Avoid plants that appear wilted or have leaves that are dead or becoming yellow.

For your hydrangea to climb on, select a trellis. Look for a trellis made of wood, wire, or tubing because climbing hydrangeas require a strong support. Cedar, redwood, and cypress are strong and long-lasting options for a wood trellis. Aluminum, copper tubing, or wire-based metal trellises are strong and won’t rust. Remember that unless a flat surface is equipped with supports, it won’t be strong enough to hold a climbing hydrangea. Consider utilizing a ladder-style trellis if you are not planting the climbing hydrangea close to an existing structure.
Choose the location for your climbing hydrangea. Growing conditions for climbing hydrangeas include both full and partial sunlight, as well as well-drained soil. Leave 15 to 18 inches between the trellis and the building if you’re planting to place it next to a wooden structure because as the hydrangea grows, it may cling to the wood and cause harm, including decay. The trellis can be securely leaning against the wall if you’re planting the climbing hydrangea next to a brick or masonry wall.

The planting area’s soil should be prepared. Utilizing a shovel or garden fork, till the soil to a depth of at least 18 inches. Remove all weeds, rocks, and large dirt clumps, and then topdress the soil with 2 to 3 inches of compost or well-rotted manure.
Before you plant the climbing hydrangea, erect the trellis. Depending on the trellis’s nature, installation may call for metal stakes or fencing spikes to properly support the trellis. Make sure the wooden posts, if you use them, have a preservative applied so they won’t decay. Before you put the climbing hydrangea on the trellis, make sure the paint is completely dried if the trellis needs to be painted.

Create a hole that is 2 to 3 times as broad and 6 inches deeper than the hydrangea’s root system. Plant the hydrangea in the hole after slidding it out of its pot. Ensure that the hydrangea’s root system is slightly submerged in the soil at its top.
Fill the hole with water, let it drain, and then backfill it with the soil you set aside. To get rid of any air bubbles, tamp the earth down with a shovel as you advance. Water the hydrangea once more after the soil has been added to the hole. To level the soil with the surrounding ground if it settles, apply extra.

By encircling the trellis with the vine, you can train the hydrangea. Every couple of days, this should be done. Pinch the vine’s tip with your fingers when it reaches a height of 6 to 12 inches. This will motivate the vine to develop more branches. Each young branch’s tips should be pinched until they are 6 to 12 inches long. The vine will be considerably fuller and take longer to reach the top of the trellis.
Maintain training the vine as necessary. For the first season, keep the soil moist. After that, the climbing hydrangea should have formed roots and only require water during hot, dry spells.
Choosing a climbing hydrangea
The lovely white blossoms in early summer are a nice addition on climbing hydrangeas, which are excellent practical climbers for covering shaded walls or fences. They may be permitted to climb up medium-sized to large trees. Hardy and simple to grow is the deciduous Hydrangea anomala subsp. petiolaris. Hydrangea seemannii and Hydrangea serratifolia, two evergreen climbing hydrangeas, provide year-round interest but require a warm, protected environment to flourish successfully. Despite being initially robust plants, they occasionally become a little slow. Although climbing hydrangeas are not picky about their soil, plants may struggle in very moist or chalky circumstances.
Buying a hydrangea
Climbing hydrangeas can be found in the “climbing plants” area of garden centers. They are often sold in pots of 2 to 3 liters. Plants purchased through the mail could be smaller.
When to plant
As soon as you buy your climbing hydrangea, plant it. Spring or autumn are the ideal seasons for planting. Plants grown in containers can be planted all year long as long as the ground is not frozen, flooded, or very dry in the summer.
Soil preparation
Climbing hydrangeas are typically planted in the soil at the base of walls or fences, which is in a rain shadow and so prone to drying out. Dig in an organic soil improver, such as garden compost or a manure-based soil conditioner, to the planting area rather than just the planting hole to aid in establishment. Per square meter, add a bucketful (yard).
Support
Even though they can cling to themselves, climbing hydrangeas typically need assistance getting started, such as wires or a trellis. Till the young shoots develop aerial roots that connect, confine them. Because mature plants are heavy, begin with a strong support.
How to plant
- Before planting, thoroughly water the pot.
- Allow around a 45cm (18in) spacing between the plant and the wall when planting against a wall or fence. Otherwise, a spacing of 20–30 cm (8–1 ft) is adequate.
- Create a planting hole that is three times bigger and as deep as the rootball.
- To prevent planting too deeply, the surface of the compost in the pot needs to be level with the surrounding soil.
- firmly in place
- Reduce soil drying out by mulching with a soil conditioner, but leave a 10-15cm (4-6in) gap around the base.
- Put water in, at least the amount found in a large watering can.
How can a climbing hydrangea be started?
Early in the summer, this robust, woody deciduous vine bears huge, flat, white blooms in addition to lovely, dark green, glossy foliage. Climbing hydrangeas may flower in partial shade, unlike many other vines. It may grow up to 50 feet tall and, like ivy, attaches itself to walls, fences, and buildings via holdfasts or tiny rootlets. At first, climbing hydrangea can be a slow-growing vine, but once it gets going, it will take off and bring years’ worth of beauty. Hydrangeas that climb require a sturdy structure to climb on or up. Its strong growth can liven up a house corner or a north wall. The peeling bark, which is cinnamon-colored and interesting in the winter, is an extra draw.
Although climbing hydrangea is hardy to zone 5, colder areas in our location may require protection. Grow climbing hydrangea plants that you bought in the spring from a neighborhood garden center and plant after all risk of frost has passed. As long as the plant receives adequate watering, you can also plant in the summer. Plant in full sun (warmer locations) to partial shade in a spot with rich, well-drained soil that has been composted. Away from hot, dry areas. The climbing hydrangea will flower more in the sun and less in the shade. Plants should be spaced 5 to 10 feet apart.
Regular waterings and a covering of bark mulch should be used to keep the soil surrounding climbing hydrangeas evenly moist. Apply a layer of compost and a little amount of an organic plant food as fertilizer in the spring.
Similar to Boston ivy, climbing hydrangeas should be planted against masonry, stone, or brick walls, as well as against rot-resistant, unpainted wooden walls. The holdfasts will leave stains next to vinyl or regular wood siding, and rot and mold growth may occur on the siding as well. If growing near a building on a wooden or metal trellis, place the trellis at least three feet away from the building. After flowering, prune climbing hydrangeas to control their development. It does not spread as quickly as ivies do. With the growing, have patience. It typically takes a climbing hydrangea 3 to 5 years to reach the flowering stage. Perennial vines, according to an old proverb, “first sleep, then creep, then leap.” Except for animals, climbing hydrangeas have no severe pests.
Climbing hydrangea should be grown along a wall, structure, or fence where it can remain there permanently. It’s ideal for a neglected east or north wall along a garage or home side. Climbing hydrangea can be grown on arbors, pergolas, and trees. Just be certain the buildings are sturdy enough to carry the weight.
The green-leaved, white-flowered variety is available at most garden centers. ‘Miranda’ is a brand-new variegated leaf cultivar with white flowers and cream and green leaves.
How much time does a climbing hydrangea require to grow?
The Garden Hydrangea, H. macrophylla, and Hydrangea anomala are related to one another. However, anomala is in a league of its own due to its tendency of climbing.
Size and Growth
Dark bark, little branchlets emerging from the sides of the structure, and oval leaves with small toothed edges are the distinguishing features of Hydrangea petiolaris.
The season-long color change of the dark green leaves begins with dark green foliage and progresses to a lighter yellow as fall approaches.
For the first three to five years, climbing hydrangeas grow slowly, but once established, they can accelerate their growth.
It has a vine-like growth pattern and when fully grown, can reach heights of 30 to 50 feet and a breadth of 5 to 6 feet.
Young plants make wonderful patio exhibits in pots. Even after many years, climbing hydrangea plants grown in containers can be easily maintained to reach heights of 8 or 9 feet.
Needs Help To Climb
When supported properly, Hydrangea petiolaris develops aerial rootlets that adhere to the stems, much like ivy does.
To first tie the plant to the supporting framework, it is crucial to train the stems early in life.
Give plants a strong trellis to grow on, or attach them to a wall or another sturdy structure. A wall facing either east or west is a wise choice.
Flower Color and Fragrance
These plants eventually adorn themselves with huge flower heads of delicately fragrant white flower clusters that can reach a height of 8 inches. These flowers often bloom in the early summer.
These white flower clusters are made up of two different kinds of blooms that work together to create the “lacecap effect.”
Large, noticeable, but sterile flowers with flashy white sepals surround the edge of the cluster.
The genuine, relatively unnoticeable, greenish-white fertile flowers are in the center of the cluster.
After fertilization, flowers in the wild produce seed capsules with brown wings.
Light and Temperature
The majority of flowering vines cannot withstand partial shade, but climbing hydrangeas can. They will, however, grow the healthiest when planted in direct sunlight.
Better flowers typically result from more light. Ideal sun exposure is six solid hours in the full sun.
The heat and humidity do not favor this plant. It may risk getting scorched if the daily temperature rises beyond 70 degrees Fahrenheit.
The plant needs a constant temperature of 65 degrees Fahrenheit for six weeks in order to set buds.
Additionally, climbing hydrangeas are not highly resistant to frost and can suffer damage if exposed to it.
Watering and Feeding
Hydrangeas that climb benefit from regular watering. They prosper in soil that is consistently moist.
Make sure plants receive regular, even irrigation that is sufficient to keep the soil moist.
How is hydrangea that climbs attached?
Hydrangea climbing is misunderstood. It has a reputation for being a temperamental bully who develops slowly at first and then quickly. Friends, have faith; Hydrangea anomala petiolaris is merely the victim of rash judgment.
It is true that starting a business often takes three to five years. Because of this, it is better to plant it, give it some water to help it grow (hydrangeas love water), and then let it alone. Simply carry on with your daily activities in the garden, and one day you’ll wonder, “Hey, I wonder how that climbing hydrangea is doing? And when you look at it, it will be attached to whatever it is that you are growing it up and will have developed a little bit.
You should then just take a step back. Even while it takes time to establish itself, once it does, it moves quickly. and leaves. and leaves. It can in reality reach heights of 30 to 50 feet.
The climbing hydrangea connects via aerial rootlets on its stems, unlike other vines that either cling to a structure with tendrils or require attachment. These can be fastened to practically any non-metallic surface, including trees, siding, bricks, fences, and so on.
Don’t worry about this habit. When new owners came into the home next door, a climbing hydrangea was killed, my gardening acquaintance told me with shock. They tore the vines out of the house in order to paint it. She made the point that the vines might have been peeled back, painted, and then guided back to the house where they could have been temporarily fastened until new aerial rootlets took over.
In its third year here, the climbing hydrangea on the wall began to spread out. It thrives in complete shade on the north side.
When deciding where to place this vine, it’s important to take its size and mounting style into consideration. It will devour that for lunch, so don’t expect it to respect a nice 4-by-6-foot trellis. But this is where it excels: This vine will completely cover a big region. The finest part is that it will perform where few other plants would.
Because climbing hydrangea thrives in partial to complete shade, this is the case. There are very few vines that will accomplish that. In milder climates, it can tolerate some sun exposure as well, provided the soil is moist but well-draining.
It’s a four-season plant in my opinion. Its spherical leaves appear in the spring, shiny and bright green. Lace cap flowers are the star of the summertime show. It turns a vivid yellow in the fall, and in the winter, the exfoliating bark and dried flowerheads add texture to an otherwise flat environment.
It can be an expensive plant because it takes so long to establish, but it’s worth it to spend more money on a bigger plant. By buying time, you.
In person, this entrance arch of climbing hydrangeas on Mackinac Island is stunning.
I’ve never seen a climbing hydrangea before. I knew I had to cultivate this plant the moment I saw it during a garden tour covering the full west side of a house.
I have two hydrangeas that climb: one on an ash tree that will undoubtedly die from emerald ash borer damage shortly, and another one that is growing on the north side of the garage that I hope will completely cover that side. When the time comes, I want to top the ash tree slightly above where the vine will grow, which will probably be around 30 feet (well above the second story window I look at it from).
Both of these, in my opinion, are genuine garden features—the kind you might not immediately notice. When you do, however, you come to appreciate exactly how fantastic they are.
