Do Osteospermun flower a second year,my last years plants are still green and I was wondering if its best to discard them and buy new ones.
Thanks Verdun,I think they were called Voltage.
Osteospermum voltage yellow is a tender perennial.If you cut it down now, it will bush and reflower this summer.It is usual to take cuttings off tender perennials to overwinter in a frost free place, but this winter is so mild,I think many will have overwintered safely in sheltered positions.
If they are in a pot, I would repot into next size up and feed it.
Thanks Fidgetbones,will do.
