Slovenian gardeners advised on hydrangea leaf browning and calcium‑potassium balance

Hydrangeas can develop brown, brittle leaf edges when exposed to high temperatures, strong afternoon sun, and dry soil. The advice stresses checking soil moisture below the surface, watering deeply to reach 15‑20 cm, and avoiding both under‑ and over‑watering. Signs of disease such as fungal spots may mimic heat damage, so proper soil aeration and careful fertilisation are recommended.

In greenhouse vegetable production, the antagonistic relationship between calcium and potassium is highlighted. Maintaining the correct nutrient ratio improves plant resistance, fruit taste, and yield, especially after a cool May that slows root development. Precise fertilisation and regular watering are essential for healthy growth.
