Overwintering
Can anyone please advise me how best to care for Osteospermums over the cold winter period? I have several plants which are under cover, but still in flower! Should I consider cutting them down at this time wonder? Any help would be appreciated. Brian

As most Osteospermums can only be considered half hardy, it's always best to propagate new plants by taking cuttings each year. This is preferable to over-wintering large plants.
