Watering bans in the garden: When thirst becomes the norm

The watering ban in many regions includes a ban on water abstraction, watering between 10 am and 7 pm, and watering in private households. These measures are intended to conserve scarce drinking water supplies but can have unintended consequences for gardens and plants. Green spaces act as natural air conditioning systems and filter particulate matter, provide habitats for animals and support biodiversity. Furthermore, healthy soils act as water reservoirs, gradually releasing water or allowing it to seep away during heavy rain. To ensure they can fulfil this vital function even during dry spells, they require targeted watering. 

Why we must not let our gardens dry out 

But how can we comply with the restrictions whilst still supporting our plants?  

• If tap water cannot be used, collected rainwater should be used instead. Careful use of this precious resource is key. With drip irrigation, the correct amount of water is delivered drop by drop directly where it is needed: to the roots.  

• If watering is only permitted at restricted times, an automatic watering system is helpful. Smart controllers such as the GARDENA smart Dual Water Control allow two areas of the garden to be watered separately and automatically. As the watering schedules can be adjusted, watering within the permitted time is straightforward.  

 Regardless of local regulations, there are simple ways to manage your water supply sensibly:

• Loosen the soil & mulch: Loosened soil and a layer of mulch help retain moisture in the soil for longer – so you don’t need to water as often. 

• Water the most important plants first: prioritise young plants, vegetables and delicate species, as their roots do not yet reach deep into the soil. 

• Water infrequently but thoroughly: If you water thoroughly and vigorously once every few days, the plants will develop deeper root systems. This allows them to draw water from deeper layers of soil.  

• Water early: Watering about an hour before sunrise allows the still-cool soil to absorb the water more effectively.  

• Automated drip irrigation: Irrigation becomes even smarter and more precise when combined with a smart sensor. This measures the moisture in the soil. If the soil is moist enough, the next watering cycle is suspended, avoiding unnecessary watering. 

• Collecting rainwater: Barrels or cisterns reduce drinking water consumption and provide plant-friendly, soft water. 

“Water is a precious resource that must not be wasted. However, in times of water scarcity, blanket watering bans can have serious long-term consequences – such as soil drying out, plants dying and green spaces being lost permanently. We all have a responsibility to use water precisely – with solutions that preserve green spaces even in dry times.” – GARDENA
