I got my hydrangea for about 2 weeks now. I put it in a spot where it gets morning sun until 2pm. It was doing ok for a while, but on Sunday, it got seriously sunburn. The huge leaves just became crispy dry. I don't get it, the soil is still moist, the sun didn't sudenly beame stronger on the same spot. How could it happen?
Now, I moved it under the balcony where it gets full shade.
