Hello everyone, I need urgent help with my Hydrangeas! We have one older hydrangea plant that seems to be doing quite well. However we recently bought two new ones, and they don’t seem to be having the same luck.
All of the flowers have turned brown, but they do not feel dry or brittle. The stems are still green and upright, but they seem to have tiny black spots. The leaves have turned very dark green, some seem to be blackening around the edges, and they look very droopy. My question is: have we been underwatering, overwatering, or is this some sort of disease?
Extra info: they were repotted recently. We used multi-purpose compost from GoodHome. When we first got them the weather was sunny and relatively warm, it has now become rather cold and cloudy. We’ve been watering roughly once a week. All other flowers we purchased are doing very well.
Any help would be greatly appreciated!
