This year I have grown Castle of Mey sweet peas and hope
to show them at the local show next Saturday.
Problem is, they don't very nice after the first day.
As staging is the night before the show has anyone any tips for
keeping them looking good. I have tried sugar, drop of bleach and
a coin in the water. None of these work. Hope you can help.

This is not something I have tried with show plants so don't know if it will
work. But what I do with all cut flowers is put 6 drops of Bach Rescue
Remedy in the water and it does make them last longer.
