My osteo has gone mad and I really need to cut it back.  I'm not sure how to tackle it, so any help would be greatly appreciated 

I take it your osteospurmum is a ground covering hardy type? Mine is spreading quite a bit,I have trimmed some of it back already. I wasn't shy. And it is ok. I would do it when it isn't too hot. Try not to cut too much of the old woody bit.

Osteospermums benefit from being cut back now.  Lift  those straggly stems and trim back quite severely.  Look out for stems that may have rooted....often they do.  And take cuttings too...they root easily now in gritty compost.

Osteospermums in Cornwall are like  bread and butter.  They grow everywhere here.

Perfect timing! I have two osteo planted last year (ground cover on a slope) which are now spreading beautifully. We did take cuttings in the autumn which are now decent sized plants, but I hadn't thought about cutting back (even though that's actually my favourite job!).

Thanks for the info!

they are really easy to pull out as the roots don't seem to be very deep. I removed some and found that it was like a hotel for slugs underneath! Never seen so many in one spot before....or since!

I pulled mine out from last year and grew new ones from seeds, blue and white. Everyone germinated and are now good sized plants. Rather treat them as annuals and grow new each year.

I agree with tootles about the slugs, they dont eat them just live there.

Or, you could pin those spreading stems into the ground....nick them first ...and still cut back a little.  They will readiy form new plants and thicken out beautifully
