Second question: We have a fairly young Philadelphus coronarius, which has grown very strongly this year and I should like to propagate it. Are semi-ripe cuttings the way forward? I know it's only the beginning of July, and probably a bit early yet, but the new growth looks perfectly ready, and I should like to make sure the cuttings have as long as possible to establish themselves before winter hits us. Also - at the node, above or below the node, and rooting powder or not?
