Just a thought for those of us subjected to deluges recently. I have always found it beneficial to lift up sodden stems of perennials ( and shrubs), and give them a gentle shake to rid them of the extra weight burden of water. They spring back better, not always quite as before the wetting, but better than leaving them prostrated. It won't prevent all those nasties which lurk around in wet and humid conditions but it gives everything a fighting chance. Lifting with the tines of a border fork rather than by hand eliminates a personal dowsing. It is a summer version of removing heavy snow during the winter! Strategic use of Y-stakes can assist too. Sorry no before and after photos available. I only thought of posting after my remedial trip round the garden.
