The weather has been very hot (low 90's) and humid. Several plants like the ferns in the deep shade seemed to have exploded in growth during this period. I thought these ferns were killed off by the heavy rains earlier this year but they look very good right now.

However...

The peonies have developed what appears to be powdery mildew. Almost overnight. It wasn't there a few days ago and now the plants are covered with the stuff. I'll be trying several things this weekend to retard or eliminate that.
