Can anyone hazard a guess as to what is wrong with this hydrangea
The soil I have is quite chalky so not sure if that is best suited to the hydrangea. I had been watering the plant every couple of days with about a litre of water. I am in Glasgow and weather hasn't been that warm. I don't think I was watering enough, so now I am filling a 10l watering can and watering every 2-3 days. Is this too much water? Not sure if plant is too far gone.
