Broadleaf P4 Water Retention Granules 25kg

Broadleaf P4 Water Retention Granules 25kg are premium super-absorbent polymer crystals designed to improve soil moisture retention and reduce drought stress for trees, shrubs, bedding plants, container-grown crops, and green roofs. These highly efficient granules absorb and store hundreds of times their weight in water, releasing it slowly to plant roots as the soil dries, ensuring consistent hydration and promoting robust growth.

Ideal for landscape contractors, tree planting teams, green roof installers, horticulturists, and professional gardeners, Broadleaf P4 reduces watering frequency, protects plants during dry periods, and enhances transplant success. Perfect for use in sandy, free-draining, or drought-prone soils, these granules support strong root development, improve survival rates, and contribute to sustainable landscaping practices.

Broadleaf P4 is cost-effective, long-lasting, and easy to integrate into planting schemes, composts, and growing media, making it a trusted choice for both commercial projects and domestic gardens.
