Gaura - do you deadhead to prolong?
Hi there - I have had some great clumps of Gaura this year, all grown from seed. It never seems to stop flowering but sometimes, some of the long stems go bare. Should I cut those back down and expect more flowers? Also - do I need to cut it right back in the autumn, or wait until spring, or not cut it back at all?? Thanks for any help you can give
