How to Grow Marguerite Daisy
Argyranthemum frutescens
Marguerite daisies are half-hardy sub-shrubs grown as summer bedding in the UK. Buy as plug plants in spring or take cuttings from overwintered stock. Plant out after the last frost in full sun and well-drained compost. Feed weekly and deadhead regularly for non-stop flowers from May to October. Not frost-hardy — take cuttings in August or bring plants under cover before first frost.
When to Start
Best started from plugs, corms, or slips. Pot up indoors 6 weeks before last frost, then plant out once soil reaches 10°C.
