Fixing Shasta Daisy Decline: Water Management and Sun Requirements

Shasta daisies yellowing and blackening from the bottom up usually signal water issues: either frequent sprinkler drift (causing fungal problems) or insufficient deep watering (causing drought stress).

• Water deeply with a soaker hose or sprinkler—hand watering is too shallow.
• Water in morning so foliage dries before night.
• Use organic fertilizer in spring; avoid synthetic hose-end sprayers (can burn).
• Ensure 5+ hours of sun, including noon hour, for good flowering.
