Gardens and other green spaces are highly sought after in urban settings right now. And drinking water is a precious resource that needs to be used efficiently and responsibly all around the world. Does the increasing need to economise clash with the desire for a garden that has to be properly looked after and watered? Luckily, there are smart solutions that can be used to align the needs of people and nature in a meaningful way.

More than half of the world’s population lives in towns and cities. In the European Union, that figure is currently standing at about 75 percent and looks set to keep on rising.1 Urban life is the way forward. This means that interactions with nature and time spent outdoors are becoming more and more precious, with gardens and green spaces improving the quality of life in cities more than anywhere else. Whether they’re in an urban or rural setting, though, green spaces are more than just somewhere for people to relax and unwind. Plants absorb CO2 and filter particulates and pollutants from their surroundings, improving the local climate and air quality. Flower beds, vegetable patches, shrubs and wildflower meadows provide a habitat for a host of animals and support biodiversity and the conservation of birds, mammals, and insects. Where there are plants, it is also easier for the soil to absorb and store water in the soil, which will prove incredibly important if extreme weather conditions do become more frequent as expected. Hot and dry spells are being followed by heavy rain more and more. If surfaces are sealed or spaces are covered with gravel to create low-maintenance gardens designed to save on water, the water struggles to soak away or cool and evaporate when it finally does rain.

Saving water with gardens
There are lots of benefits to gardeners introducing a variety of plants to their gardens, patios or balconies, but they need to take care of them and water them in return. At the height of summer, when plants are in desperate need of water, drinking water is increasingly likely to be scarce too. There is a call for water-saving measures at this point, which can impact upon gardens and green spaces depending on just how serious the water shortage is. But this is a tricky situation because gardeners who deprive their gardens of water will see the benefits for biodiversity and the microclimate vanish. Once soil has become hard and dry, it’ll struggle to absorb the water effectively when the next bout of heavy rain arrives. This can put pressure on the drainage system and cause flooding. So the answer is to apply a clever approach to green spaces and use resources sparingly.

Gardens are not the biggest factor contributing to water consumption in a household. And there are ways to reduce the amount of water and maintenance required in a garden too. For example, plants can be cleverly grouped together based on the amount of light and moisture they need and plants can be matched to the local conditions to start with. Other minor habit changes can help save resources and keep plants thriving. Examples include watering early in the morning when the water can be absorbed better by the soil and using collected rainwater.

Monitoring, measuring and controlling with smart systems
Drip irrigation can then be used to provide plants with exactly the amount of water they need right at their roots. And because fungal diseases are no longer able to settle on wet leaves, the plants are healthier too. This method ensures that the nutrients in the soil aren’t washed away into deeper soil layers or even into the groundwater. Another benefit is that the system deters weeds, as the available water is largely absorbed by the cultivated plants and flowers. Smart irrigation systems have sensors to measure the moisture content of the soil and local weather forecasts are factored into the schedule too, ensuring that the plants are only watered when they need to be.

Pragmatic, fast and convenient
There is no better way to describe the GARDENA Micro-Drip-System, which has been completely overhauled for 2023. Installation is even more straightforward and flexible now, with the option of having the system above or under the ground. Watering ornamental plants and crops with pinpoint accuracy is ideal for balconies and patios, vegetable and flower beds, raised beds and hedges. Sets are available for all use cases and size requirements and all the elements can be mixed and matched as desired. Another practical benefit is that the easily installed drip irrigation system can be disassembled or extended just as quickly if changes are being made to the plant arrangements for the following year.
