Planted Hydrangea macrophylla early summer, was thriving for first 6-8 weeks but now some of the leaves are looking burnt and a bit dried out, but more distressingly all the flowers are fading in colour and turning brown, soil is moist I’m sure it doesn’t need water but I have no idea what is happening to it.
