Risks and benefits of growing ivy on the facade

Often considered a weed because of its aggressiveness, ivy raises concerns about potential damage to buildings and the environment. However, with proper control, it can be grown with benefit. UAportal has prepared the advantages and disadvantages of planting this plant near the house.

Why ivy is so disliked

There is a widespread belief that ivy should be eradicated because of its potential harm to buildings and the environment. This is true, as it can spread rapidly, suppressing weaker plants and demonstrating resistance to various external factors.

However, if cultivated wisely, pruned regularly, and controlled, ivy can bloom without causing damage. By limiting the length of the shoots, you can enjoy the beauty of lush green foliage throughout the year.

Eliminating negative consequences

Ivy has strong adventitious roots that cling to cracks, but it is important to note that it does not directly damage facades. Instead, the existing cracks serve as an entry point for the roots.

The damage can also be explained by the weight of the ivy. Still, ivy can play a beneficial role as a natural insulation for buildings. By creating a protective layer, it reduces the summer heat absorbed by the walls and provides insulation against winter frosts.

Myths about ivy

Contrary to popular belief, ivy does not retain moisture in the walls. In fact, the dense foliage protects the wall from rain by minimizing water absorption. One should also remember that it can be difficult to remove ivy completely due to its tightly attached aerial roots. Moreover, even after removal, the remains of torn off fragments may remain visible.

Benefits of ivy

Despite some negative effects, ivy can contribute to the comfort of occupants by providing insulating properties. In summer, its foliage acts as a shield, preventing direct sunlight from heating the facade.

In addition, the dense foliage cools the surrounding air near the wall, with a temperature difference of 3 to 4 degrees Celsius. This cooling effect is influenced by the evaporation process, which decreases as the outside temperature decreases.
