Toprose (5-6-12 + Magnesium & Iron)Toprose is much more than an ordinary fertiliser. 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.Established roses: Apply evenly to the soil around the plants and hoe in lightly. Keep off stems and leaves. Water if the soil is dry.First Feed: Spring – Apply 28g (1oz) (approx. one handful) around each plant when active growth starts.Second Feed: Summer – Apply 28g (1oz) (approx. one handful) around each plant after the first flush of flowers has faded.New Roses: You can put in bare-rooted plants between late October and March. The ground must be neither frozen nor waterlogged. Container-grown plants can be put in at any time of the year provided the soil condition is suitable.Barerooted plants: Dig a hole which is wide enough and deep enough to allow the roots to spread out fully. Average size is 60cm across and 25cm deep. Mix one handful of toprose with the bottom soil. Bud union should be 2.5cm (1 inch) below the soil level when planting is completed.Container Grown Plants: Water thoroughly before planting or removing the container. Cut down the side of the container when stood on the base of the hole. Remove this cover very carefully. Mix one handful of Toprose with the bottom soil.
