How to Grow and Care
Hydrangeas prefer a sunny or semi-shaded position in a cool area of the garden with shelter from cold, drying winds. For this reason, they are especially useful for brightening up shaded borders and make a lovely feature in the dappled shade of woodland gardens. Try to avoid hot, sunny areas and east-facing spots where colds winds can damage the spring growth.
Grow Hydrangea plants in any rich fertile, moist soil. It's a good idea to work in some well-rotted manure or compost before planting Hydrangeas, and they will always appreciate a mulch of organic matter in spring to help conserve moisture at their roots and feed them up for them for the coming growing season. On light soils, it is a good idea to feed Hydrangeas with an ericaceous fertilizer. See more at How to Grow and Care for Hydrangeas.
