Blue hydrangeas will gradually turn pink if they are not grown in acid soils. To keep the flowers blue, even in neutral or alkaline soils, just feed them during the growing season with this specially formulated colourant - it really works! Dilute at 30g to 5 litres of water. One pack is enough for one large hydrangea for an entire season
