Many of my Shasta daisies have a similar problem, and I'm looking for help. Some of these plants were purchased early in the year, and they were blooming much earlier than those that came up naturally. They are different varieties; Becky, Banana Cream, Daisy May, and White Mountain.
Basically, the plant looks healthy with abundant blooms, but then the plant turns brown and dies back. I'll attach a photo, to give you an idea. If you look closely, you can see the new (green) growth at the soil line.
Is it possible that they have spent their blooms (because they were grown early for retail) and are just dying back?
I did fertilize them with milorganite, and wonder if perhaps that is the cause (?).
Thanks in advance for your help

All my varieties do that. I just cut them back to the new growth.

This is normal behavior for daisies. Once the leaves are unsightly, and there is no more signs of new flower buds on the stems, cut them down low, and fertilize the new growth.

Thanks to you both for the reply.

Our new(this year) daisies plant was doing well and blooming. Then the centre started to drop and go brown including young flowers. What should we do?

my daisy has healthy leaves on top but no flowers , the bottom of the stems are brown with no leaves! Any help as to what's going on?

I have never seen any of the die-back you are all talking about. My yard is in danger of being taken over by Shasta Daisies. East coast/west coast?

East Coast (Mid-Atlantic) Zone 6a. I had posted this some time ago and now accept it as normal behavior for my daisies. I cut back the foilage almost to the ground, fertilize and enjoy the new growth that forms at the base.
