This high-quality Screened Peat is carefully processed to achieve a consistent particle size, making it well suited for a wide range of horticultural applications. Peat improves soil structure by increasing moisture retention while maintaining adequate aeration for healthy root development. Its high organic matter content helps create a stable growing environment and supports plant establishment. Peat is also commonly used to lower soil pH, making it particularly beneficial for acid-loving plants and specialised growing media blends.
