The shasta daisies and daylilies in my flower bed are about 4 years old. They started out fine this year, but during the past few weeks most of the flowers on them have died. The foliage still looks okay. This week I noticed that the flowers on the tickseed in the same bed have started dying. I water at least once a week. Why is this happening and how can I stop it? Thank you for any help you can offer.
If the summer heat has hit you may need to increase watering.
Have you inspected the plants for insects or disease?
You may want to treat with Neem Oil as if works as a insecticide and fungicide.
