Penstemon - cut back now or in Spring?- UPDATE.....
Another of my woody plants it has become tall/overgrown & woody at the bottom. Should I prune it now or end of April? When I prune it, how low can I cut it off...to the base, the top or bottom of the wood or with some greenery left?
Thank you for such helpful replies. The reason my plant got so overgrown & woody was that I didn't know if/how/when to prune it in the first place. So I am excited about taking cuttings now & will try both the water & compost suggestions. But I don't know how exactly to prune it because I chopped off a previous plant in Spring (apart from 3 twigs) & obviously I got something wrong as it didn't grow anything else this year. So what is the correct way to prune it? I welcome your advice.
