The Content Of The Article:

Almost everyone has it in the garden and almost everyone finds it beautiful. We're talking about the ivy. Especially on a facade, he cuts a fine figure. But is it even a good idea to green a facade with it?

Ivy grows well almost everywhere

Ivy is a popular and very fast-growing climbing plant that is often used for greening of the facade. In principle, this does not contradict anything, at least if you follow some instructions. Although ivy does not form roots that can cause great damage to the façade, in many cases it can be better if you decide against the greening of the façade with ivy.

Benefits of greening with ivy

✔ Ivy grows in the shade and on bad soil:

Shady locations, barren soils - these facts that kill other plants do not bother the ivy. Originally known as a forest plant, the tendril copes well with low light conditions and has a root system that absorbs nutrients even from bad soil.

✔ Ivy is very easy to care for:

In addition, ivy is very easy to clean and only needs a pruning. The plant forms single shoots with sticky roots, which firmly cling to the house wall and do not lose their hold. You do not need to water the plant, do not fertilize it, just cut it.

Disadvantages of greening with ivy

✘ a regular pruning is necessary:

Basically, you can fall back on ivy and give your house wall a fresh green. However, you should be aware that you will have to do an annual pruning. Otherwise, the plant will obscure windows and thus prevent daylight from shining into the house.

✘ Cracks in the plaster can be a problem:

However, older house façades are a bigger problem. Cracks in the plaster or if the plaster breaks up in some places, moisture settles here. Now if ivy grows over the places, not enough air gets to the plaster, so that it can dry off. As a result, mold forms. It is even more dangerous if the adhesive roots seek a way through the cracks and settle in flaws. Although they do not blow up the façade, they lead to greater damage when violently detached. Therefore, you should always inspect the façade for cracks and repair them before you start greening.

✘ Ivy can get heavy and raise roof tiles:

The vine plant is also problematic in the roof area. The shoots find their way and entwine along gutters. If the roots of the roots dissolve in the lower part of the façade, the weight of the tendril can damage the gutter. In addition, individual shoots grow well under the roof tiles. Here, the removal of the ivy is particularly important, because the shoots are thicker and more extensive, they raise the bricks and damage the roof.

✘ Spiders feel comfortable between the ivy:

Other problems can be caused by insects. Spiders feel very well between the dark tendrils of the ivy. What is a disadvantage on the one hand, however, also represents an advantage. The spiders have excellent insect protection and are henceforth plagued by fewer mosquitoes. Nevertheless, the spiders through the windows also like to come into the house, which does not like everyone.

Ivy does not grow on every facade

Even if ivy is very easy to care for and even thrives on bad soil, it does not grow on every facade:

  • fresh concrete masonry is unsuitable
  • bright facades are shunned
  • older facades with cracks should not be greened

In particular, bright facades are often rejected by ivy. Although the plant grows on the ground, it does not adhere to the facade. This is mainly due to the fact that the bright color reflects the sunlight in such a way that the adhesive roots detach from the masonry.

Conclusion:

If you want to green the façade of your house with ivy, then think twice. You have to be a bit behind and reach the roof and all the windows to keep them free of ivy. In addition, the facade must be in perfect condition. Only if you can guarantee all that, the greening of the façade with ivy is a good idea.
