shasta daisies

Question

Hello. I have been trying to grow shasta daisies for a number of years. I have had them in full sun and partial afternoon sun. However, they eventually tend to either shrivel and get yellow (like they havent had water, even though watered), or the lower part of the stems turns black and rots. I have tried fungal treatments, fertilized, but to no avail. The ones I planted for my mother though, in full sun but terrible clay soil, are doing great. Can you please advise?
Thank you.

Pruning and deadheading should help. Also make sure there is proper drainage.
