For Shasta daisies, Illinois Extension recommends full sun to very light shade and moist, well-drained soil; avoid sites that remain wet in winter.

Water thoroughly, then allow the mix to dry between irrigations; avoid keeping it saturated, especially during cool, cloudy weather. In garden beds, maintain good drainage and remove spent flowers to encourage continued bloom.
