Change hydrangea color. Unlike most flowering plants many varieties of lacecap and mophead hydrangeas can actually change color. Learning to change hydrangea color is easy. That is one of the many reasons why gardening with hydrangeas can be so much fun. You can actually change the color palette of your garden and determine the the shades and hues you want by manipulating the pH levels of the soil (acidity or alkalinity). Hydrangea colors can be endless, from vibrant pinks to frosty whites, to royal blues.
Hydrangeas will delight you with their immense mophead flower blooms which are formed from clusters of small flowers that help showcase the delicate and very elegant petals. Learn how to change the colors of hydrangeas by testing the soil pH, and by raising or lowering the levels of acidity or alkalinity in the garden soil. It is much easier to change a hydrangea from pink to blue than it is from blue to pink.
