Use hydrangea feed to create the maximum visual impact in your garden. Hydrangea feed contains the 3 major nutrients essential for healthy growth plus added magnesium and iron to encourage abundant vibrant flowers. Apply when planting and as a topdressing in the spring. Rake, hoe or fork into the top surface of the soil, and in dry weather, water well for maximum benefit. When planting mix between 70-140g with the infill, depending on the size of the plant. As a top dressing in spring apply 70g per square metre evenly over the area covered by the branch spread in early spring. Apply a second dressing after 6-8 weeks.
