Pruning Pinks and Penstemons

Not much time today so just did a bit of deadheading and weeding/tidying. I haven't had this Pink and Penstemon long. The Pink has flowered well throughout the summer with me just pinching the dying buds off; the Penstemon hasn't but there are a few new buds appearing now. Have tried removing some of the stems as well as dead flowers so will see if that works better.
