Apart from the three essential plant foods - nitrogen, phosphate and potash - it contains iron and magnesium to guard against nutrient deficiency and prevent premature leaf drop and discolouring. Toprose ensure your roses and shrubs are kept bright and beautiful, providing vibrant blooms and healthy foliage. The no mess granules are easy to apply. For established roses, just sprinkle around your roses and lightly hose. Only two applications are needed for a complete season?s feeding. When planting new roses, simply mix one handful of Toprose with the bottom soil near roots. Recommended by the Royal National Rose Society. NPK Fertiliser 5-6-12 with Magnesium and Iron.
