Which air pollution-resistant plants to plant on an urban balcony this autumn?
Every day, atmospheric pollution is becoming more prevalent in cities. However, this doesn't mean that gardening enthusiasts can't bring greenery to their balconies, terraces, or urban gardens. It is crucial to choose plants that are resistant to air pollution in order to have a healthy and beautiful green corner. But how can you determine if the atmosphere in your outdoor space is polluted? Are there any symptoms of pollution that you need to be aware of? And what are the species that best resist pollution in cities? Deavita.fr has all the answers!
In urban areas, pollution caused by industry and human activities accumulates on the leaves of plants. While some species are able to resist this pollution, others struggle to survive. In dry weather conditions, without wind or sunlight, the accumulated chemicals form a barrier that hampers photosynthesis. As a result, plants that are less resistant to atmospheric pollutants are unable to assimilate carbon dioxide, leading to stunted growth. Therefore, choosing plants that are suitable for pollution is essential, especially if you live in a city.
The Virginia creeper – climbing plant
If you have a house with a small green garden in the city, you're in luck! The Virginia creeper is perfect for dressing up the fences and facades of your property. Not only does it provide privacy, but it also withstands atmospheric pollution and enhances the outdoor space. Additionally, it can hide unsightly areas of the house. Plant your Virginia creeper in autumn or spring, after the last frost, in partial shade or full sun, and in fertile soil. The only thing to keep in mind is that this climber is invasive and grows rapidly, so regular pruning is necessary. Ivy is another good option for cleansing your property.
Rudbeckia – perennial variety
If you're looking for a perennial plant to protect your urban balcony or terrace from atmospheric pollution, consider the rudbeckia. With its bright yellow petals, this plant is perfect for adding a touch of color to your outdoor space in October and November. It is remarkably easy to grow and thrives in all types of soil and sunny gardens. The yellow rudbeckia is not only resistant to pollution but also frost and drought. Plant it in well-aerated soil between September and October, water generously, and add compost if the soil is poor or clayey. Its beautiful yellow flowers will continue to bloom until the first cold weather.
The trumpet vine – flowering climber
Also known as Campsis, the trumpet vine is an exotic climber that adds vibrant colors to gardens, balconies, and terraces from April to late autumn. It is a vigorous plant that can reach a height of 8-9 meters with a solid support to climb on. However, for small outdoor spaces, the Summer Jazz Fire variety is more suitable. The trumpet vine is resistant to sun, drought, and atmospheric pollution in cities. It thrives in well-drained, cool, and chalky soils. It can tolerate dust from transportation and human activities, as well as temperatures as low as -15°C. By planting the trumpet vine, you can enjoy a green, flowering, and protected garden all year round.
Lilac – shrub resistant to atmospheric pollution
If you want to add fragrance to your urban garden and combat the atmospheric pollutants that settle there, lilacs are the way to go. These shrubs are known for their pleasant scent and their ability to resist pollution. Plant lilacs in your garden to create a fragrant and protected environment. They thrive in well-drained soils and prefer full sun. Lilacs are not only resistant to atmospheric pollution but are also hardy and able to withstand harsh conditions. They are an excellent choice for an urban garden.
