Cuttings not rooting in water
I took some cuttings of salvias, dahlia, euonymus and aster around 4 weeks ago and only the dahlia is showing any sign of rooting (they're all in water as I've had no luck in vermiculite), what am I doing wrong? I dipped them in rooting hormone and change the water every 5-7 days. Even the dahlia only has very small white knobs which I'm not even sure are the beginnings of roots! Should I wait or pot them up anyway? Thanks!
