Marguerite Daisy Dieback: Short‑Lived Perennial Woes

Marguerite daisy (Argyranthemum frutescens) is a short‑lived perennial that often dies out in the center after 2–3 years, regardless of soil, water, or fertilizer. Fungal infection or mineral imbalance may accelerate it. Contact your local UC Cooperative Extension (Santa Cruz County) for a diagnostic sample.

Workaround

• Take cuttings annually to maintain vigorous plants.
• Replace older plants with fresh starts.
• Ensure excellent drainage and avoid overhead watering.

Accept its short lifespan and propagate regularly.
