I have been following your advice and have taken some cuttings from geraniums which have got long and straggly. I have put them into a jam jar of water on the sill of the kitchen window. Should I have dipped them into rooting powder and put them into compost or are they ok as they are? Where should I keep them over winter? I could have about 15 cuttings, each about 2″long.
Geranium cuttings are best rooted in potting compost, or a peat and sand mixture. Rooting powder helps but geranium cuttings can root without it. Fifteen cuttings in small pots can be easily accommodated on a window sill indoors with good light, potting them up in spring to grow on.
