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 an attractive feature in the dappled shade of woodland gardens. Try to avoid hot, sunny areas and east-facing spots where cold 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.
