Do Climbing Plants Damage Walls

Yes, they can harm brick walls, vinyl siding, and timber.

Aerial roots appreciate the permeable nature of bricks and stones. They’ll naturally grow into them. Old mortar is particularly prone to damage.

Also susceptible to vines, wood. Because wood is so porous, aerial roots and suckers can easily climb it. Walls that are shaded by vines and moisture-collecting vegetation are more prone to rot.

Can vegetation harm walls?

Native vines like crossvine, coral honeysuckle, American wisteria, and carolina jessamine are some of my favorites.

I would like to include vines into a landscape design since I adore the way they appear on walls.

I frequently hear people caution against planting vines and ivy on brick walls, claiming that the tendrils will damage the mortar and harbor insects.

But I wonder what the big issue is considering several cathedrals, castles, and colleges have been covered in vines for ages. Additionally, if I utilize native plants, I anticipate that even if some insects may use the vines as homes and food sources, a) the majority of the insects would be helpful, and b) predatory insects, birds, and bats would help regulate the bug population.

So, the question is, are vines really as terrible for masonry and mortar as some people claim?

ANSWER:

The simplest response to your query is “no” However, Mr. Smarty Pants enjoys elaborating…

Contrary to popular belief, vines generally cause less harm to masonry and mortar than they could. However, there are several situations where climbing vines might be problematic. It is advised to read a brief overview of vine morphology in order to better understand the challenges at hand.

Typically, vines will utilize one or more of the following four techniques to climb: scrambling, stem twining, using twining tendrils, or using holdfasts. Some other vines employ different, less typical techniques that are not covered here.

You may imagine scrambling vines as upright plants with flimsy stalks. They only grow up and over the tops of neighboring vegetation and buildings to gain height. Unless trellises are employed, scrambling vines—climbing roses are a well-known example—are typically poor options for wall vines.

Some vines cling to supporting plants or buildings by wrapping their stems around them. Vine species that frequently use this strategy to go from below to above include honeysuckles.

The majority of grape vines employ tendrils to climb. Through the use of twining tendrils, they cling to supporting objects and climb. Again, for this sort of vine to cover walls, trellises, wires, or other similar support systems are needed.

Finally, some vines, like Virginia creeper, have modified tendrils with flattened terminals that are referred to as holdfasts. These holdfasts essentially act as adhesive to support structures like tree trunks and cathedral walls. This is how Boston ivy, a relative of Virginia creeper, and English ivy cling to walls at Ivy League dormitories and some outfield walls in Chicago baseball parks.

Here are the issues. If you’ve had a holdfast-attached vine on your wall for a while and decide that you truly don’t want it there any longer, removing it can be difficult and frequently messy. Such a “cleaned” wall will typically be covered in stubborn holdfasts and remnants of tendrils and vines for some time. Bricks may sometimes get a little bit chipped during the cleaning procedure.

Many people won’t buy a house with viney walls because they dislike having their walls covered with vines. Resale may thus be a problem.

Some vines may not want to stop growing once they reach the eaves of a building, which can occasionally result in damage to the eaves, gutters, shingles, and/or youngsters who are moving slowly. Though it is not usually a problem with brick walls, the weight of vines can occasionally lead to structural failure.

As clinging vines will trap moisture on the wall and speed up the rotting of the siding, they should not be utilized on walls with wood or composite siding.

Insects, birds, reptiles, and other animals can live on vine-covered walls. Wasp nests during the summer are likely the main issue with creatures in vines.

On the bright side, a vine on a wall that faces south or west can significantly reduce the expense of air conditioning. On one of those walls, a deciduous vine will lower cooling expenses in the summer and permit sun penetration and lower heating expenditures in the winter. That is actually pretty cool.

Are vines damaging your home?

The main concern is how vines harm shingles or siding. Most vines use twining tendrils or clinging aerial roots to climb surfaces. Because their tiny immature tendrils will wrap around anything they can, twining vines can cause damage to gutters, roofs, and windows. However, as these tendrils become older and develop stronger, they can actually deform and distort brittle surfaces. Paint, stucco, and already-weakened brick or masonry can all be harmed by vines with clingy aerial roots.

Any vine will use tiny gaps or cracks to anchor itself to the surface it is growing on, whether it grows by twining tendrils or sticky aerial roots. This may result in siding and shingles being harmed by climbing vines. It is possible for vines to slither between the gaps in siding and shingles and eventually pull them away from the house.

The moisture that is produced between the plant and the house when vines are grown on siding is another issue. This moisture can cause damage and the growth of mold and mildew on the house itself. Additionally, it may cause bug infestations.

Does vegetation harm concrete?

The Himalayan-native anemone clematis (Clematis montana) is frequently used to decorate brick buildings, fences, and terraces. The vine can reach a length of 30 feet. The ideal conditions for clematis are full sun, nutrient-rich soil, and good drainage. Anemone clematis is a twining vine that needs assistance. It grows well in USDA plant hardiness zones 6 through 9.

The common periwinkle, also known as vinca vine, enhances the scenery of the home with its greenery and vivid blue blossoms. Periwinkle has low-growing, disease- and drought-tolerant, and simple-to-grow leaves that are deep green and glossy. Vinca vines (Vinca minor L.) can reach a height of 6 to 8 feet. April and May are when the plant blooms. Vinca vine won’t grow on brick, stone, or concrete when used as a foundation planting beneath bushes. In USDA plant hardiness zones 3 through 8, trailing periwinkle plants flourish.

According to Las Pilatas Nursery, the striking vine known as California grape, or Vitis californica ‘Russian River,’ is native to California and thrives in conditions resembling those in the Mediterranean. Use the vine to cover ugly fences, buildings, or landscape elements. The mortar in brick or stone walls or buildings is unaffected by the vine. California grape makes a good ground cover if no support is offered. Wisteria, bittersweet, and trumpet creeper are some other vines with twining stems.

Is it beneficial to grow plants on walls?

A fantastic method to soften the sharp edges of a garden is to grow plants up against a wall. Walls are obviously a necessary component of a home and are useful for seclusion, but they aren’t often that attractive.

Will hydrangeas that climb harm a wall?

The ideal environment for hydrangeas is dappled shade—not too bright or too dark. While Hydrangea petiolaris will thrive in the sun, the flowers’ longevity will be reduced. Avoid planting in a frost pocket and plant away from strong winds in the spring since young vegetation is vulnerable to frost damage.

The majority of soil types, including alkaline and acidic soil, are favorable for climbing hydrangeas. The optimum soil is wet and well-drained.

When to plant hydrangeas

Hydrangeas grow best in the spring or fall when the soil is warm and moist. It is possible to plant in the summer, but you must monitor the soil’s moisture content.

How to plant Hydrangea petiolaris

When handling Hydrangea petiolaris, use gloves because the leaf might hurt the skin. If your soil is thin, bulk it up with moisture-retaining organic matter before planting hydrangeas because they thrive in damp soil. A good hour or so before planting, thoroughly water the plant. A hydrangea should never be planted any deeper than it was in the pot. Well with water. Mulch after planting, preferably with leaf mold; if not, use compost or well-rotted manure. Throughout the plant’s first spring and summer, make sure it gets plenty of water.

Hydrangea petiolaris must first be trained onto galvanized wires or a trellis. You will need to assist them on their journey since after a season of growth, it will form self-clinging aerial roots and find its own way. Make sure the fence is solid if you wish to grow plants along it because mature climbing hydrangeas are hefty. Hydrangea petiolaris’ aerial roots shouldn’t harm a wall.

Does climbing ivy harm masonry?

It’s a common misconception that self-clinging climbers, especially ivy, can harm the walls of your home and garden. In actuality, there is no proof that ivy endangers sturdy brickwork.

Vine growth harms brick walls?

With the exception of leaving tendrils that can be challenging to remove, vines don’t significantly harm well-built brickwork on their own. Houses constructed prior to 1930, however, have the issue that the mortar might not include Portland cement, making it more likely to erode over time. Additionally, you might not see the structure if it is covered in ivy or vines.

Aggressive vines like English ivy can enter gaps and fissures when the mortar deteriorates. Additionally, if it were to ever be hauled away, the wall might also fall. Even while some structures with ivy covering have endured for more than a century, ultimately you have to question whether the ivy is actually supporting the building. Make smart decisions if you intend to add vines to an older house.

Here are some pointers on how to utilize vines to enhance the appearance of an older house:

Examine Mortar: In most cases, vines don’t weaken solid masonry; instead, they only take advantage of existing flaws. Before you start, have a historic preservation expert evaluate your brickwork. Before you plant anything, contact someone who can recommend the proper repairs because current mortar feels and looks different from cementless mortar. To be able to monitor your mortar in the future, it would also be beneficial for you to know what kind of mortar you have and what kinds of damage to check for.
Think Permanent: It can be quite challenging to remove climbing vines afterwards, therefore it is best to think of them as a permanent installation. Ivy and climbing hydrangea are examples of self-adhering vines that you might not want to cover your brickwork with if you’re concerned that it will eventually need repairs. Before planting, take into account the worth of your home since vines may or may not appeal to potential buyers in the future.
Consider Less-Aggressive Vines: Instead of planting English ivy, which has aerial rootlets that not only cling to the brick but may also squeeze into cracks, think about more amiable vines that are less likely to cause harm. For older buildings, Boston ivy and Virginia creeper are attractive options because their adhesive suckers don’t attach as quickly as English ivy.
Consider Non-Attaching Vines: Planting vines that aren’t directly attached to the stonework is an additional option. Jasmine, clematis, climbing roses, and wisteria are some lovely vines that thread up supports as opposed to adhering to surfaces. The advantage of using trellis, lattice, or wire to support these vines is that you may take them away from the house to examine or fix the masonry behind them.

Climbing plants harm siding, right?

Everyone has heard the unsavory stories that ivy and other climbing plants may damage your home’s exterior. However, that isn’t always the case, according to landscape architect Kim Hoyt and a 2010 research by English Heritage and the University of Oxford. In actuality, it depends on your home’s location and the material used for the exterior. Hoyt frequently advises her clients that there shouldn’t be a problem if the plant is growing on brickwork where there is good sun exposure. Climbing plants, such as Boston ivy, suction onto surfaces with sticky pads, allowing them to go up and under the wood, collecting moisture, and eventually destroying the facade. Climbing plants are more prone to cause problems on wood siding and in humid locations.

In conclusion, as long as the circumstances are ideal, you are perfectly permitted to ignore the enchanted vegetation that is creeping up your walls. And it won’t just be lovely to look at. We now have compelling evidence that ivy lessens the risks of freeze-thaw, heating and cooling, wetting and drying, and associated salt weathering through its modulation of the wall surface microclimate, according to the English Heritage assessment.

You’ve only recently come to the conclusion that your house isn’t the ideal location for a climbing vine. Hoyt reminds us that there are alternative methods for achieving a comparable lush, classic appearance. The ideal option is to grow vines up a metal armature or screen in front of an outside wall to deceive onlookers.

Here are a few of our favorite exteriors with vibrant greenery, with the case of the climbing plants closed.

Are vines harmful to wood?

The kind of vine you can securely grow on your fence depends on the sort of fence you own. Even the gentlest vines attract moisture to the wooden fence components they contact. However, due to their greater durability and reduced susceptibility to environmental harm than wooden fences, aluminum and vinyl fences fare better against the majority of vines.

For Wooden Fences

The majority of vine species are likely to pose a threat to the longevity of your wooden fence if you have one. The majority of kinds of vines should be avoided since they can cause your wooden fence to rot, break, twist, and other structural damage.

Annual herbaceous (non-woody) vines are the most secure for wooden fences. The stems of these vines can encircle your wooden fence, but they won’t harm the fence’s structure the way woody vines will. You can direct these vines to grow around fence posts or along the higher support beams of your fence, which will give them plenty of light and keep them away from the more delicate slats of your fence.

For Vinyl Fences

Since vinyl fences are built of sturdy, weather-resistant material, they can endure nearly anything, therefore they are often exempt from the structural issues that wooden fence owners worry about while growing vines on their fences.

Vinyl fences are perfect for homeowners who want their climbing vines to increase the privacy of their rooms because of how durable they are. Perennial vines that can cling to plastic fences include coral honeysuckle and clematis. These plants can typically cover the height of your fence in one growing season and offer a lot of coverage in a short amount of time.

Although even woody vines resembling strongmen won’t significantly alter the structural integrity of your vinyl fence, the plant can nevertheless trap moisture against it, and moisture attracts a wide variety of species, from algae to bugs. Fortunately, there’s no need to worry if algae grows on your vinyl fence. Because vinyl is non-porous and does not allow stains, it is simple to keep clean.

On the other side, bugs might be a concern. A bushy vine’s robust structure, moisture content, and delectable plant matter could appear like a polite invitation to pests wishing to settle down, endangering the other plants in your yard. To keep the rest of your outdoor space secure, be sure to find out what pests, if any, enjoy your chosen vine and take the necessary precautions against bug infestation.

For Aluminum Fences

Of all fences, aluminum fences are possibly the easiest to beautify. Their sturdiness and open-lattice construction make them a great base for a “living fence.” Aluminum, which withstands moisture and resists rust, is unaffected by heavy, strong woody vines like wisteria, climbing hydrangea, rambling roses, and others that might topple other fences. On aluminum fences, even the grapevines flourish. Within a few growth seasons, these plants can completely cover your area while enhancing the flavor and color of the room. Some plants, like bougainvillea, have spiky stalks that may even deter burglars more!
