Dying lilies of the valley

Asked July 10, 2019, 7:44 PM EDT

My Lilies have been dying off starting in late June for the past three years. I have tried a pesticide for grubs but no change noted. I am enclosing a picture. What do I have to do?

This is not uncommon in our area for lily of the valley to go dormant once it has bloomed. Mine is doing the same at the moment.
You can tidy them up a bit by removing dead or dying leaves and putting them in the trash.
