dear all, rooting hormone compound: how important is this for cuttings? just seen article where it says unless it's fresh don't bother (Bunny G.in DT, I think), but just been to a local meeting where I was told it's vital for success (though not where to get it in France!). Never seriously tried cuttings before (my summer bought pelargoniums now struggling would be my first ones). Any advice? Have no greenhouse but I have an unheated but light guest-bedroom (!) (Wisely no one visits in winter).
