Care
Watering
Keep the soil regularly moist, especially during the first weeks after sowing. During active growth, water once or twice a week depending on weather conditions. Reduce watering during heavy rain to prevent waterlogging.
Sunlight
Italian ryegrass prefers full sun exposure for optimal growth. It also tolerates partial shade, but its productivity and density will be reduced. Ensure good light to promote vigorous foliage.
Soil
Choose well-drained, fertile soil with sufficient organic matter. This grass adapts to most soil types but fears chronic waterlogging. Adding compost before sowing significantly improves results.
Cutting and mowing
Carry out a first cut when Italian ryegrass reaches 8 to 10 cm in height. Mow regularly at 4 to 6 cm to encourage tillering and thickening. Avoid cutting too short to preserve plant vigor.
Fertilizer
Apply a balanced nitrogen-rich fertilizer at the beginning of growth to stimulate leaf development. With intensive grazing, split nitrogen applications optimize productivity. Excess fertilizer can promote fungal diseases.
Diseases and pests
Italian ryegrass can be affected by fungal diseases such as rust or powdery mildew, especially in warm, humid conditions. Ensure good air circulation in the field and avoid excess moisture. Good crop rotation and regular mowing reduce risks.
Did you know?
Italian ryegrass has been a plant of choice in intensive agriculture since the nineteenth century: its ability to germinate and grow extremely quickly made it the ideal ally for European farmers to improve pasture yields. Its success is such that it ranks among the most widely sown forage grasses worldwide for both extensive and intensive livestock farming.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
