Vitax Rose Food is a top quality rose fertiliser containing the three major plant foods – nitrogen, phosphate and potash – together with iron and magnesium to ensure healthy green leaves and abundant blooms. It has an NPK of 5-5-10 with iron. Vitax Rose Food should be applied evenly around the base of the plant in early Spring, and watered in if the soil is dry. You can make a repeat application during the summer prior to a second flush of blooms. Vitax Rose Food can be mixed into the planting hole of new roses, or used as a top dressing on established rose beds. It can also be used on other flowering trees and shrubs to great effect.
