Hi I grow lots of osteospermum
I have cuttings in a tray right now ....unheated greenhouse ..no fleece
Best kept fairly dry but don't let them dry out
They are hardier than pelargoniums
Cotty1000, do you increase your watering in march? maybe they get too wet. Do you pot on then and maybe overwater then? Did you take your cuttings too late?
Cuttings are best taken in September so that by early winter they have formed good roots and able to tick over until spring.
In cold areas cover with fleece.....in the greenhouse.
Here in Cornwall osteospermums usually grow and flower during the winter.
Varieties too vary in hardyness....Cannington Roy is prob hardiest. Treso Purple is less hardy but a wonderful colour. Cuttings from September will flower from following mid summer onwards
