Hydrangea macrophylla Magical Jade

To plant Hydrangea macrophylla, choose spring or early autumn for the best results. The plant prefers slightly shaded areas like those near an east-facing or northern wall. Be sure to shield it from cold, drying winds. Although it doesn't need ericaceous soil, hydrangeas thrive in deep, cool, and fertile soil. Consider enriching the soil with a good base fertiliser before planting. 

If the soil is dry near the base of the wall, plant the root ball at least 30-40 cm (11.8-15.7 in) away from it. Adding well-rotted compost will help retain coolness in the soil. Hydrangeas are very hardy and can withstand cold climates.

Pruning hydrangeas involves removing faded flowers on the first bud or a pair of buds below. Cut back a quarter or a third of the oldest stems to promote young shoots. This pruning should be done annually in March or April. Guide the young stems to distribute them, and they will naturally cling to a support.
