Osteospermum used to be treated as an annual in this country and was grown from seed. However, if buying one of the many ready-grown varieties, make sure you incorporate some grit for added drainage and water in well. Osteospermums look great planted in containers with grasses and other summer bedding plants.


How to propagate osteospermum

A tender perennial, ensure the survival of your favourite osteospermum by taking cuttings in spring or late summer. Select a non-flowering shoot and cut the tip off, strip the leaves and dip in hormone rooting powder. Plant several cuttings in well drained compost around the edge of a pot. Water well and pot on when roots have formed.

Osteospermum: problem solving

Osteospermums can attract aphids. Find out ways of dealing with aphids in our guide. Osteospermums can get downy mildew if not regularly watered.


How to care for osteospermums

Some varieties of osteospermum are tender or half-hardy, particularly in cooler areas. These can be grown as annuals or moved indoors in autumn to overwinter. Cut back hardy osteospermums in early spring or after flowering in autumn. All osteospermums need watering regularly – don’t allow them to dry out.

Feed weekly through the growing season with a general plant food to encourage continuous flowering and dead head as flowers fade.
