What's wrong with my hydrangea leaves??
I got a new hydrangea plant less than a week ago and it's in a pot that's a bit too small for it. I intend to re pot it once it's used to it's new environment. I've been watering once a day since the pot is quite small. While watering today I noticed a dead leaf with black spots (2nd pic) and when I checked the plant I found that some of the bottom leaves had these black spots on them. What's going on here? Please help!!
