German municipalities impose strict garden watering bans as summer heatwave hits
A severe summer heatwave is prompting German cities to enforce strict garden‑watering restrictions. In Munich, homeowners, allotment and small‑garden owners may only water before 9 a.m. and after 7 p.m.; private lawns are prohibited entirely. Violations can attract fines of up to €50,000. Similar rules apply in Hannover, where sprinklers and irrigation systems are banned between 11 a.m. and 5 p.m. on days above 27 °C. The Bavarian Garden Academy advises deep, infrequent watering – roughly 15–20 litres per square metre per week – and recommends early‑morning irrigation to reduce evaporation. Experts also warn that midday watering can cause leaf burn on hairy or hydrophobic foliage. Gardeners are encouraged to use simple tools such as a small glass to gauge water output from sprinklers. Despite water scarcity, demand for irrigation equipment is rising; Swiss retailer Galaxus reported a 75 % increase in sprinkler sales in June‑July 2026, with related products also climbing sharply. The University of Budapest’s research confirms that smooth, hairless leaves do not burn under water droplets, while hairy leaves are more vulnerable. Across Austria and Germany, advice emphasizes watering the soil, not the foliage, mulching to retain moisture, and avoiding over‑watering that promotes fungal disease.
