During the summer, lawns endure greater stress and wear. By utilizing advanced products and following some simple practices, we can maintain the health and appearance of our grass while promoting its resilience.

General Principles
The primary goal is to protect the root system from intense sunlight and minimize stress on the leaf system.

Cutting Height

No matter the lawn's purpose (whether for sports or decoration), it’s advisable to increase the cutting height during summer. Raising the height to 45-50 mm for recreational lawns and 30-35 mm for ornamental lawns helps to shade the crown and roots, protecting them from sunburn and excessive water loss. Extend the interval between cuts to 7-8 days, and avoid removing more than 1/3 of the leaf length per cut to prevent matting.

The Role of Irrigation

Excess water can be more damaging than a lack of it. In summer, we often overwater the lawn, inadvertently encouraging fungal diseases and soil compaction. The soil's ability to absorb and store water depends on its structural characteristics. Watering should be based on these characteristics, as well as factors like outdoor temperature, seed mixture, and sun exposure.

Water should penetrate at least 15-20 cm into the soil with each watering. Water in the early morning or late afternoon to prevent prolonged wetness. A sprinkler irrigation system is recommended.

Fungal and Weed Control
Lawn diseases appear in patches, often causing sudden yellowing within 2-3 days. By avoiding prolonged leaf wetness, you can reduce the spread of diseases. For persistent issues, use specific plant protection products and seek expert advice.

Weeds compete with the lawn for water, especially in summer. If weeds are widespread, consider using selective weedkillers during this period.

Fertilisation

Potassium (K) is crucial for lawn health, second only to Nitrogen (N) in the amount absorbed annually. Potassium influences carbohydrate, amino acid, and protein synthesis and translocation. It regulates stomatal opening and closing, which controls respiration rates and water consumption. Combined with Phosphorus, Potassium enhances rhizome and stolon elongation, improving rooting, resistance to trampling, and overall resilience.

Pre-summer fertilisation with high Potassium is important to counteract environmental stresses like extreme temperatures, fungal diseases, and wear. KB Evergreen Antistress is a specific fertilizer for summer and fall, high in Potassium and Magnesium, with Nitrogen released over 2-3 months.

By following these tips, you can maintain a healthy, vibrant lawn throughout the summer.
