Hi Folks, I planted some Hydrangeas August 8th of this year and I am a little concerned about them. They get 6 hours morning sun, water from my drip line off my irrigation every 2 days for 45 minutes. They were Strawberry Vanilla Hydrangeas, They looked OK coming from the nursery but some of the flowers are turning brown and are crispy. Am I supposed to cut those off? I may have gotten some of my reading on them mixed up and I am scared to mess with them. I am also concerned about the yellow leaves and the brown spots. the yellow leaves are very minimal but the brown spots on the leaves are on every plant. Just looking for some good tips on caring for these plants going into the fall because I am a first timer with these.
