Matthew Pottage, curator at RHS Wisley said: “Hydrangeas like reliable moisture in the summer, so don’t plant them in a dry position.”
Avoid a south-facing spot, and ensure there is some protection from frosts and shade from the blazing afternoon sun.
Some species of hydrangea tolerate full sun, but if yours is more sensitive, it will become stressed by drought in the summer.
Once you have chosen a good new spot, it’s important to get the ground ready before digging up the plant.
Leigh advised: “In light soil, add in some organic matter at planting to help with moisture.”
