My hydrangeas do well in April and early May but come June they wilt. I have covered them with pine straw and water them daily in the morning preferably. Please advise what can be done. They are two years old and under shade but get some sun. You think I have overwatered them? Will removal of pine straw help or does it need fertilizer?

It may be overwatered. Check the soil and make sure that it is damp, but not soaked. Allow it to dry out some between waterings. It should also have good drainage. Root rot also may have set in if it was overwatered in the past.
