Good luck with your cuttings Gattina. This is not the time to feed anything as you don't want to encourage new vulnerable growth just before the weather turns cold, but do feed with a long lasting fertilizer in spring. Some people use blood, fish and bone, I throw slow release fertilizer pellets all round the garden in about April, mix it into compost for containers to be planted, poke holes in the compost of containers that are keeping their plants and dribble granules in. I find it works well.

The latin name is 'Argyranthemum' - but some people do call them Marguerites. I managed to keep one large plant over the winter in an unheated greenhouse, but it wasn't really worth it, because it went really woody, so cuttings are the way forward.

Thankyou, Spritz and Beattie. I wouldn't expect to feed them now, just trying to build up a little knowledge for following seasons. Maybe I should start keeping notes - the geriatric memory gets worse by the day.
I had a feeling there might be a "..anthemum" somewhere in the name. They make a wonderful display in early summer if you mass them in pots and tubs, and if you have the time to deadhead them EVERY day they keep going right through until October/November if the weather is kind. I'm off to do even more cuttings, I think, and won't even bother with overwintering the parent plants. Growing from seed hasn't really worked so far, and isn't worth the candle.
