Adjusting hydrangea flower colour
Some of the hydrangea varieties we sell will not change colour when planted in different soils (EG: White form) while others do.
Many of hydrangea varieties have their flower colour determined by the acid/alkaline pH levels in the soil.
Many people are content to plant them straight into their chosen positon without adding anything to the soil and letting the natural soil condition determine their own colours, whilst other people want a specific hue and will work on their soil to influence the flower colours.
Much of Australia has acidic soil, which means that flower colours of many of the moptop hyrdangea tend towards blue.
Hydrangeas need aluminum sulfate to colour blue.
This becomes accessible in acidic soil.
Also if you add aluminum sulphate it will help increase acidity in the soil.
To obtain the pinks and reds you will need to increase the alkalinity of the soil. Adjusting the pH levels of your soil.
“Making it Happen”
Increasing the pH level.
Powdered lime is the most popular way to (increase your pH) make your soil more alkaline.
You can also use wood ash or powdered shell. Reducing the pH level.
You can lower the pH by adding any of the following to your soil at the recommended rates given on the packaging: Ferrous sulphate, aluminum sulphate, Sulphur and also the addition of organic matter will reduce the pH as it decomposes.
Pine tree needles will also work well.
