From David Paul Morgan
Michael Strawson asks if adding aspirin to water for cut flowers can prevent
them from drooping
(20 October, p 62).
Cut flowers in the supermarket already come with a sachet containing powder
that is added to the vase water. It contains mostly salicylic
acid—aspirin. “Rooting powder” for cuttings also contains salicylic acid.
It looks like this use is quite common.
