Does anyone happen to know why it is that pinching out the very tip of
freesia and gladiolus flowers causes them to open more fully? It's of no
huge importance but I was doing it yesterday (wedding flower arranging) and
suddenly realised I do it but don't know why! There must be some
'mechanism' in the plant that's triggered, perhaps?
