Too late to prune Salvias and Penstemons?
Hi everyone, hope someone can throw some advice my way. I've been busy with work and other things so am running late with my gardening jobs. My salvia hot lips have just started their first flush of flowers but really need to prune them back as they've now taken oven and are huge, but am I too late to give them a hard prune, I really don't want to cut back if it's at the expense of losing flowers this year. Same goes for Penstemons, if I hard prune now will they still flower this year? Thanks in advance for any help
