CARING for HYDRANGEAS
CLIMATE Cool to temperate.
ASPECT
Partial shade – preferably sun in the morning and shade in the afternoons.
WATER
They’re party plants, so love a regular drink. Keep your soil moist.
SOIL Hydrangeas love a well-drained growing medium, either in a pot or a garden bed. If you have clay soil, dig in rich organic matter to improve drainage.
FOOD
For a flourish of flowers, feed soil in spring or early summer with rich organic matter and add controlled-release fertiliser during flowering.
PRUNING
Pick flowers for indoor display in summer, then deadhead in autumn and prune back stems in late winter or early spring to about the lowest two buds. Remove old wood.
