Marguerites thrive in full sun conditions and need well-draining soil, ideally with added organic matter. They prefer consistent watering but are drought-tolerant once established. Temperature-wise, marguerites can handle some variation but should be protected from frost. In terms of challenges, marguerites might face issues like aphids, whiteflies, and fungal diseases. Seasonally, marguerites should be deadheaded to promote blooming in spring and summer, might require protection or moving indoors in winter, and should be trimmed back in autumn.
