iGrow Carpet Summer Advance 15-0-10 + 2% MgO A controlled-release summer fertiliser that keeps your lawn thick, dark green and growing steadily through the warmest months. Iron free, so no orange staining on paths or drives. Safe for kids and pets when used as directed. The science bit Nitrogen (15% N)Powers steady, lush green growth through summer. Drives photosynthesis and keeps your lawn looking its best when it's under the most pressure. Phosphorus (0% P)Deliberately excluded. Phosphorus moves slowly through soil and isn't needed by established grass in summer. We've left it out and focused on what your lawn actually uses. Potassium (10% K)Helps your lawn hold moisture during dry spells and recover quickly from drought stress, keeping colour vibrant for longer. Magnesium (2% MgO)Fuels chlorophyll production, giving you a deeper, richer shade of green without the staining you get from cheaper iron-based products.
