I have several blue/purple hardy geraniums (Not Johnsons Blue) After flowering, should I just cut off the seed heads or be more severe. Will they flower again this year. Several grow along the base of a stone wall and some others are in borders. I do cut them right back in late Autumn
Thank you for that, I think I'll just leave it as is with the seed heads off for now.
Our weather here is awful, so much rain, and not much sun, puts you off working in the garden.
