Change blue and purple flowers to pink, and maintain pink coloured hydrangeas with this rapid action, pinking tonic. The Yates Hydrangea Pinking Liquid Lime & Dolomite is an easy to use liquid formulation that supplies nutrients to produce pink blooms and magnesium for greener foliage.
It can also be used to sweeten acidic soils which are ideal for growing vegetables and sweet peas.
Keep in mind that soil PH affects the colour of hydrangea flowers.
- Acidic soil (pH 4.5 - 5.5) will produce blue flowers.
- Less acidic soil (pH 5.5 - 7) will produce pale, purplish flowers.
- Alkaline soil (pH 7 - 8.5) will turn flowers pink. You can make your soil more acidic with Yates Soil Acidifier.
