I have two approx 20' hedges of 6-8' forsythia growing along a damp shady woodland border of my property. I neglected to prune them immediately after they finished blooming this year. (yeah, alright, and the past 2 years also) I was wondering just how much damage I'd do to next year's bloom if I hacked at them now? A very wise old gardener whom I learned much from as a child, told me the best time to prune is when your tools are sharp and you have the time. I recently replanted and neatened up the lowers growing borders between and adjacent to the forsythia so it's making the unruly shrubs look extra sloppy and overgrown. What do you think? Is it worth the risk of reducing next year's golden bells or would I still have a decent show of flowers?
Thanks for your info and opinions.
