Hydrangeas bear flowers in shades of pink, white or blue. Some varieties – particularly mophead and lacecap varieties – are known for their ability to change colour in different soils. This colour change is due to the soil pH – hydrangeas growing in acid soil tend to have blue flowers, while those growing in alkaline soil tend to have pink flowers. For the best flower colour, choose cultivars that give the best colours for you soil’s pH. Always check the plant type before pruning hydrangeas as different types are pruned in different ways.
