I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
You can shear the brown blooms off and then fertilize them and water it in well. This should invigorate the plants and make them stronger. If so you may get a good rebloom.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
